CAUTION

The Global Positioning System is operated by the United States government, which

is solely responsible for its accuracy and maintenance. The system is subject to changes

which could affect the accuracy and performance of all GPS equipment. Although the

GARMIN GNS 430 is a precision electronic NAVigation AID (NAVAID), any NAVAID

can be misused or misinterpreted and therefore become unsafe.

Use the GNS 430 at your own risk. To reduce the risk of unsafe operation,

carefully review and understand all aspects of this Owner’s Manual and the Flight

Manual Supplement, and thoroughly practice basic operation prior to actual use. When

in actual use, carefully compare indications from the GNS 430 to all available navigation

sources, including the information from other NAVAIDS, visual sightings, charts, etc.

For safety, always resolve any discrepancies before continuing navigation.

The altitude calculated by the GNS 430 is geometric height above mean sea level

and could vary significantly from altitude displayed by pressure altimeters in aircraft.

GPS accuracy may be degraded by the U.S. Department of Defense-imposed Selective

Availability (SA) program. With “SA” on, GPS altitude may be in error by several hun-

dred feet. Never use GPS altitude for vertical navigation.

GPS receivers operate by receiving and decoding very low power radio signals

broadcast by satellites. It is possible that in some situations other radio equipment or

electronic equipment used in close proximity to a GPS receiver may create electromag-

netic interference (EMI) which may affect the ability of the GPS receiver to receive and

decode the satellite signals. In such event, the interference may be reduced or eliminat-

ed by switching off the source of interference or relocating equipment.

The Jeppesen database incorporated in the GNS 430 must be updated regularly in

order to ensure that its information is current. Updates are released every 28 days. A

database information packet is included in your GNS 430 package.

Pilots using an out-of-date database do so entirely at their own risk.

NOTE: This device complies with Part 15 of the

FCC limits for Class B digital devices. This equip-

ment generates, uses, and can radiate radio fre-

quency energy and, if not installed and used in

accordance with the instructions, may cause harm-

ful interference to radio communications.

Furthermore, there is no guarantee that interfer-

ence will not occur in a particular installation.

If this equipment does cause harmful interfer-

ence, the user is encouraged to try to correct the

interference by relocating the equipment or connect-

ing the equipment to a different circuit than the

affected equipment. Consult an authorized dealer or

other qualified avionics technician for additional help

if these remedies do not correct the problem.

Operation of this device is subject to the follow-

ing conditions: (1) This device may not cause harm-

ful interference, and (2) this device must accept

any interference received, including interference

that may cause undesired operation.

The GARMIN GNS 430 does not contain any

user-serviceable parts. Repairs should only be made

by an authorized GARMIN service center.

Unauthorized repairs or modifications could void

your warranty and authority to operate this device

under Part 15 regulations.

TAKEOFF TOUR

Power On

The GARMIN GNS 430 provides you accurate navigational data and communi-

cation capability, along with non-precision and precision approach certification in

the IFR environment. The Takeoff Tour is designed to familiarize you with the

operation of the GNS 430 — including powering up the unit, changing frequen-

cies, entering data, performing a simple direct-to, selecting IFR procedures and

provides a limited introduction to using flight plans. In addition, this section briefly

covers the default navigation, map and frequency pages available as part of the

NAV page group. These pages will be used for most of your in-flight navigation.

The Takeoff Tour assumes that the unit and antennas have been properly

installed and you have not changed any of the GNS 430’s default settings. If you

have changed any of the factory default settings (position format, units of measure,

selectable fields, etc.), the pictures shown here may not exactly match what you see

on your GNS 430. Prior to using your GNS 430 for the first time, we recommend

that you taxi to a location that is well away from buildings and other aircraft so the

unit can collect satellite data without interruption.

Powering up the GNS 430

The GNS 430’s power and COM volume are controlled using the

(power/

volume) knob at the top left corner of the unit. Rotating it clockwise will turn unit

power on and increase the COM radio volume. After turning the unit on, a

welcome page will be displayed while the unit performs a self test, followed by the

the land data page.

The database confirmation page will appear next, which shows the current data-

base information on the NavData card (with the valid operating dates, cycle num-

ber and database type indicated). The database is updated every 28 days, and must

be current for approved instrument approach operations. Information on database

subscriptions is available inside your GNS 430 package.

To acknowledge the database information, press the

key.

The database confirmation page shows the

effective and expiration dates of the Jeppesen

database on the NavData Card.

The welcome page appears when the GNS

430 is turned on. During the time this screen

is displayed, the GNS 430 performs a self-test

to ensure proper operation.

430MANF.qxd 7/24/00 4:43 PM Page 4

TAKEOFF TOUR

Instrument Panel

Self-Test

Once the database has been acknowledged, the instrument panel self-test page will

appear. To ensure that your GNS 430 and any connected instruments are working

properly, check for the following indications on your CDI/HSI , RMI, external annun-

ciators and other connected instruments:

• Course deviation - half left / no flag • Glideslope - half up / no flag

• TO/FROM flag - TO • Time to destination - 4 minutes

• Bearing to destination - 135° • Desired track - 149.5°

• Distance to dest. - 10.0 nautical mi. • Ground speed - 150 knots

• All external annunciators (if installed) - on

The instrument panel self-test page indicates the currently selected OBS course,

fuel capacity (CAP), fuel on board (FOB) and fuel flow (FF). The fuel capacity, fuel on

board and fuel flow may be manually entered if your installation does not include con-

nection to sensors which automatically provide these figures.

To enter fuel capacity, fuel on board or fuel flow figures (if not provided by sensors):

1. Rotate the large right knob (

) to select the CAP, FOB or FF field.

2. Rotate the small (

The instrument panel self-test page includes selections to set fuel on board

(FOB) to full capacity and access the checklists page. This allows you to quickly set

fuel to full limits and display any checklists you’ve entered, such as start up or take-

off checklists.

To set fuel on board to full (if not provided by sensor):

1. Rotate the large right knob (

) to highlight Set Full Fuel?.

2. Press

and verify that fuel on board (FOB) now matches the fuel capacity (CAP)

figure. Fuel on board will now be reduced, over time, based on the fuel flow (FF) figure.

To view the checklists page:

1. Rotate the large right knob (

) to highlight Go To Chklist? and press

2. Rotate the large (

) right knob to select the desired checklist, then follow the steps on

page 147 to execute each step in the selected checklist.

3. Once you complete the desired checklist(s), press the small right knob (

) to return to

the checklists page. Press the small right knob (

) again to return to normal operation

on the satellite status or map pages.

Once you’ve verified instrument operation with the instrument panel self-test

page displayed, press the

key.

The satellite status page will appear as the GNS 430 begins to collect satellite

information. An ‘Acquiring’ status will be displayed on the satellite status page, and

the signal strength of any satellites received will appear as “bar graph” readings.

This is a good indication that you are receiving signals and a position fix will be

determined. Following the first-time use of your GNS 430, the time required for a

position fix will vary—usually from one to two minutes.

Select “Set Full Fuel?” to set fuel on board

(FOB) to full capacity.

Select “Go To Chklist?” to display the check-

list page and any available checklists. The

GNS 430 can hold up to nine checklists with

up to 30 entries in each checklist.

If the unit can only obtain enough satellites for 2D navigation (no altitude), the

unit will use the altitude provided by your altitude encoder (if one is connected).

If the GNS 430 has not been operated for a period of six months or more, it may

have to ‘Search the Sky’ to collect new data. This means the unit is acquiring satel-

lite data to establish almanac and satellite orbit information, which can take 5 to 10

minutes. The satellite status page will display a ‘Search Sky’ status, and the

message annunciator (MSG), above the

key, will also flash to alert you of a

system message, ‘Searching the Sky’.

To view a system message, press

The message page will appear and display the status or warning information

applicable to the receiver’s current operating condition.

To return to the previous page after viewing a message, press

again.

The satellite status page shows the ID num-

bers for the satellites and the relative signal

strength of each satellite received (as a “bar

graph” reading.

‘Search Sky’ indicates that satellite almanac

data is not available or has expired (if the

unit hasn’t been used for six months or more).

The data will be recollected from the first

available satellite.

The ‘INTEG’ annunciator (bottom left corner

of the screen) indicates that satellite coverage

is insufficient to pass built-in integrity moni-

toring tests. In the example above, not enough

satellites are being received to determine a

position.

Selecting COM and

VLOC Frequencies

While the GNS 430 is acquiring a position, let’s take a minute to dial in the

active and standby frequencies you’ll be using for the first phase of your flight. The

GNS 430’s display is divided into separate ‘windows’ (or screen areas), including a

COM window, VLOC window and the GPS window (the right 3/4 of the display).

Pushing the small left knob (

) activates the tuning cursor in the desired fre-

quency window. To select the active frequency, you must first enter the frequency in

the standby field, and use the

(or

) key to move it to the active field.

To change the standby communication frequency:

1. Press the small left knob (

) if needed, to move the tuning cursor to the COM window.

2. Rotate the large left knob (

) to select the MHz, and the small left knob (

) to select

the kHz of the desired frequency.

Flight Plans

The GNS 430 lets you create up to 20 flight plans, with up to thirty-one way-

points in each flight plan. Flight plans are created, edited and activated using the

key. The FPL page group includes two pages: the active flight plan page and

the flight plan catalog. The active flight plan page provides information and editing

features for the flight plan currently in use (referred to as “flight plan 00”). The

flight plan catalog serves as the main page for creating new flight plans, as well as

editing or activating previously created flight plans.

Since using flight plans is arguably one of the more complex features of the GNS

430, we’ll only discuss it briefly here — focusing on creating a new flight plan and

activating it to use for navigation. After reading through this brief introduction,

answers to additional questions you may have about flight plans can be found in the

reference section, starting on page 54.

Auto Squelch

Section 1

Communicating with the GNS 430

The GNS 430 features a digitally-tuned VHF COM radio that provides a seam-

less transition from communication to navigation, bringing the two most important

functions in flying together in one panel-mounted unit. The GNS 430’s COM radio

operates in the aviation voice band, from 118.000 to 136.975 MHz, in 25 kHz steps

(default). For European operations, a COM radio configuration to allow for 8.33

kHz steps is also provided (see pages 160-161).

Volume

COM radio volume is adjusted using the

knob. Rotate the

knob clock-

wise to increase volume, or counterclockwise to decrease volume.

Squelch

The COM radio features an automatic squelch, providing maximum sensitivity

to weaker signals while rejecting many localized noise sources. You may wish to

override this automatic squelch function when listening to a distant station or when

setting the desired volume level. The

knob allows you to disable the automatic

squelch and keep the COM audio open continuously.

To override the automatic squelch, press the

knob momentarily. Press

again to return to automatic squelch operation.

Press the kknob momentarily to override

the automatic squelch. Note the “RX” receive

indication when receiving a station.

“TX” appears at the upper right corner of the

screen while transmitting.

5COM Window and Tuning

Communication frequencies are selected with the tuning cursor in the standby

COM frequency field, and using the small (

) and large (

) left knobs to dial in

the desired frequency. The standby frequency always appears below the active fre-

quency. The active frequency is the frequency currently in use for transmit and

receive operations.

A frequency may also be quickly selected from the database by simply highlight-

ing the desired frequency on any of the main pages and pressing the

key. This

process is referred to as auto-tuning. Once a frequency is selected in the standby

field, it may be transferred to the active frequency by pressing the

key.

While receiving a station, an “RX” indication appears in the upper right corner

of the COM window — to the immediate right of “COM”. A “TX” indication

appears at this location while you are transmitting.

Emergency Channel

The GNS 430’s emergency channel select provides a quick method of selecting

121.500 MHz as the active frequency in the event of an in-flight emergency. The

emergency channel select is available whenever the unit is on, regardless of GPS or

cursor status, or loss of the display.

To quickly tune and activate 121.500, press and hold

for approximately two

seconds.

Stuck Microphone

As mentioned earlier, whenever the GNS 430 is transmitting, a ‘TX’ indication

will appear in the COM window. If the microphone is stuck or accidentally left in

the keyed position, or continues to transmit after the key is released, the COM

transmitter will automatically timeout (or cease transmitting) after 35 seconds of

continuous broadcasting. You’ll also receive a “COM push-to-talk key stuck” mes-

sage as long as the stuck condition exists.

Default NAV Page

The first NAV page is the default NAV page. This page may be quickly selected

from ANY page by using the

key.

To select the NAV group and display the default NAV page, press and hold

The default NAV page displays a graphic course deviation indicator (CDI) across

the top of the page. Unlike the angular limits used on a mechanical CDI coupled to

a VOR or ILS receiver, full scale limits for this CDI are defined by a GPS-derived

distance (0.3, 1.0 or 5.0 nm), as indicated at both ends of the CDI. By default, the

CDI scale will automatically adjust to the desired limits based upon the current

phase of flight: en route, terminal area or approach. You may also manually select

the desired scale setting as outlined on pages 153 and 155.

The graphic CDI shows your position at the center of the indicator, relative to

the desired course (the moving course deviation needle). As with a traditional

mechanical CDI, when you’re off course simply steer toward the needle. The

TO/FROM arrow in the center of the scale indicates whether you are heading to

(an up arrow) the waypoint or if you have passed the waypoint (a down arrow).

Directly below the CDI appears the active leg of your flight plan, or the direct-to

destination when using the

key. This will automatically sequence to the next leg

of your flight plan as you reach each interim waypoint. If no flight plan or direct-to

destination has been selected, the destination field will remain blank.

Selecting Desired On-Screen Data

At the bottom of the default NAV page you’ll find six user-definable fields which

display the data you’ll need as your flight progresses. By default these fields display:

distance to destination (DIS), desired track (DTK), bearing to destination (BRG),

ground speed (GS), ground track (TRK) and estimated time en route (ETE).

However, each of these fields can be custom-tailored to your preferences by

selecting a different data item. Available data items include:

• Bearing to destination (BRG) • Course to steer (CTS)

• Distance to destination (DIS) • Desired track (DTK)

• En route safe altitude (ESA) • Estimated time of arrival (ETA)

• Estimate time en route (ETE) • Ground speed (GS)

• Minimum safe altitude (MSA) • Track angle error (TKE)

• Ground track (TRK) • Vertical speed required (VSR)

• Cross track error (XTK)

If no flight plan or direct-to destination has been selected only speed, track, alti-

tude and minimum safe altitude data may be displayed. All other data types will

appear as blank lines—on the default NAV page—until a destination is selected.

To select a different data item for any data field:

1. Starting with the default NAV page, press the

key to display an options menu.

2. The Change Fields? option is already highlighted, so press

An autozoom feature is available which will automatically adjust from an en

route scale of 2000 through each lower scale, stopping at a scale of 1.0 as you

approach your destination waypoint. The autozoom feature is turned on/off from the

map setup page described on page 36.

The map page also displays a background map showing lakes, rivers, coastlines,

highways, railways and towns. When a map scale is selected below the lower limit

at which the map detail was originally created, an “overzoom” indication will appear

on the map display, below the scale reading. “Overzoom” indicates that the detail at

this scale may not accurately represent actual conditions. If you continue to zoom in

to lower scale settings, “overzoom” will be replaced with “no map” and the geo-

graphic detail is removed from the map display (but, the airport and navaid detail

will remain).

The “Setup Map?” option (described on page 35) allows you to define the maxi-

mum scale at which each map feature will appear. This provides you with complete

control to minimize screen clutter. You can also quickly remove items from the map

using the

key.

To quickly declutter the map display, press the

key momentarily (as often as

needed) to select the desired amount of map detail.

The right-hand side of the map page includes four user-selectable data fields. By

default, the displayed data is: destination waypoint name (WPT), desired track

(DTK), distance to destination waypoint (DIS) and ground speed (GS). Any of these

data fields may be changed to display a different data type, as outlined on page 37.

You may also remove the four data fields from the map to show a larger map image,

as described on page 37.

Satellite Status Page

The satellite status page (the fifth NAV page) provides a visual reference of GPS

receiver functions, including current satellite coverage, GPS receiver status and

position accuracy. The satellite status page is helpful in troubleshooting weak (or

missing) signal levels due to poor satellite coverage or installation problems.

As the GPS receiver locks onto satellites, a signal strength bar will appear for

each satellite in view, with the appropriate satellite number (01-32) underneath

each bar. The progress of satellite acquisition is shown in three stages:

• No signal strength bars— the receiver is looking for the satellites indicated.

• Hollow signal strength bars— the receiver has found the satellite(s) and is col-

lecting data (see illustration at center left).

• Solid signal strength bars— the receiver has collected the necessary data and

the satellite(s) is ready for use (see illustration at bottom left).

The sky view display (at top left corner of the page) shows which satellites are

currently in view, and where they are. The outer circle of the sky view represents

the horizon (with north at top of the page); the inner circle 45° above the horizon;

and the center point directly overhead.

Each satellite has a 30-second data transmission that must be collected (hollow

signal strength bar) before the satellite may be used for navigation (solid signal

strength bar). Once the GPS receiver has determined your position, the GNS 430

will indicate your position, track and ground speed on the other navigation pages.

The GPS receiver status field (see preceding page) will also display the following

messages under the appropriate conditions:

• Searching Sky— The GPS receiver is searching the sky for ANY visible satel-

lites. You will also be informed of this status with a

“Searching the Sky” message.

• Acquiring Sat— The GPS receiver is acquiring satellites for navigation. In this

mode, the receiver uses satellite orbital data (collected contin-

uously from the satellites) and last known position to deter-

mine which satellites should be in view.

• 2D Navigation— The GPS receiver is in 2D navigation mode. Altitude data

will be provided by an altitude serializer.

• 3D Navigation— The GPS receiver is in 3D navigation mode and will compute

altitude using satellite data.

• Poor Coverg— The GPS receiver cannot acquire sufficient satellites for

navigation.

• Rcvr Not Usbl— The GPS receiver is unusable due to incorrect initialization or

abnormal satellite conditions. Turn the unit off and on again.

• AutoLocate— The GPS receiver is looking for any available satellite. This

process can take up to five minutes to determine a position.

430MANF.qxd 7/24/00 4:43 PM Page 45

PROCEDURES

Approach Examples

The satellite status page also indicates the accuracy of the position fix, using

Estimated Position Error (EPE) and Dilution of Precision (DOP) figures. DOP

measures satellite geometry quality (i.e., number of satellites received and where

they are relative to each other) on a scale from one to ten. The lowest numbers are

the best accuracy and the highest numbers are the worst. EPE uses DOP and other

factors to calculate a horizontal position error, in feet or meters.

Vertical Navigation Page

The GNS 430’s vertical navigation page (the last NAV page) allows you to create

a three-dimensional profile which guides you from your present position and

altitude to a final (target) altitude at a specified location. This is helpful when you’d

like to descend to a certain altitude near an airport or climb to an altitude before

reaching a route or direct-to waypoint. Once the profile is defined, message alerts

and additional data on the default NAV and map pages will keep you informed of

your progress.

Approaches, Departures & Arrivals

The GNS 430 allows you to fly non-precision and precision approaches to airports

with published instrument approach procedures. All available approaches are stored

on your Jeppesen NavData® card, and are automatically updated when you replace

the card with a new one. Subscription information for NavData cards is included in

your GNS 430 package.

The procedures page (shown at top left) is displayed by pressing the

key. The

procedures page provides direct access to approaches, departures and arrivals—based

upon the active flight plan or direct-to destination. In either case, the departure and

destination airports must have published procedures associated with them.

To select an approach, departure or arrival:

1. Press the

key to display the procedures page.

2. Rotate the large right knob (

) to highlight Select Approach?, Select Departure? or

Select Arrival? and press

3. A window will appear listing the available procedures. Rotate the large right knob (

) to

highlight the desired procedure and press

. (When a direct-to destination is selected,

departures are offered for the nearest airport.)

4. A second window will appear listing the available transitions. Rotate the large right knob

(

) to highlight the desired transition waypoint and press

. (The approach Vectors

option assumes you will receive vectors to the final course segment of the approach and will

provide navigation guidance relative to the final approach course.)

5. Rotate the large right knob (

Approaches 5

Not all approaches in the database are approved for GPS use. As

you select an approach, a “

GPS

” designation to the right of the

procedure name indicates the procedure can be flown using the

GPS receiver. Some procedures will not have this designation,

meaning the GPS receiver may be used for supplemental navigation guidance only.

ILS approaches, for example, must be flown by tuning the VLOC receiver to the

proper frequency and coupling the VLOC receiver to the external CDI (or HSI).

Once an approach is selected, it may be activated for navigation from the proce-

dures page. Activating the approach overrides the “enroute” portion of the active

flight plan, proceeding directly to the “approach” portion (for a full approach, directly

to the initial approach fix). Activating the approach also initiates automatic CDI scal-

ing transition as the approach progresses.

To activate an approach:

1. Press the

key to display the procedures page.

2a. Rotate the large right knob (

) to highlight Activate Approach? and press

Another procedures page option allows you to activate the final course segment of

the approach. This option assumes you will receive vectors to the final approach fix

(FAF) and guides you to intercept the final course, before reaching the FAF.

To activate the approach, with vectors to final:

1. Press the

key to display the procedures page.

2b. Rotate the large right knob (

) to highlight Activate Vector-To-Final? and press

In many cases, it may be easiest to “Load” the full approach while still some dis-

tance away, enroute to the destination airport. Later, if vectored to final, use the steps

above to select “Activate Vector-To-Final”—which makes the inbound course to the

FAF waypoint active. Otherwise, activate the full approach using the “Activate

5Basic Approach Operations

The GNS 430 provides non-precision approach guidance using its built-in GPS

receiver. The GPS receiver can also be used as a supplemental aid for precision

approaches, but the localizer and glideslope receivers MUST be used for primary

approach course guidance.

Approaches designed specifically for GPS are often very simple and don’t

require overflying a VOR or NDB. Currently, many non-precision approaches have

“GPS overlays” to let you fly an existing procedure (VOR, VOR/DME, NDB,

RNAV, etc.) more accurately using GPS. To date, there are over 2,400 GPS-only

approaches and over 2,900 GPS overlay approaches.

Many overlay approaches are complex (in comparison to GPS-only approaches).

The GNS 430 displays and guides you through each leg of the approach—automati-

cally sequencing through each of these legs, up to the missed approach point

(MAP). Approaches may be flown “as published” with the full transition — using

any published feeder route or initial approach fix (IAF) — or may be flown with a

vectors-to-final transition.

Approach operations on the GNS 430 will typically begin with the same basic

steps:

1. Select the destination airport using the

key, or as the last waypoint in the active flight plan.

2. Choose the Select Approach? option from the procedures page (see page 66) or from the active

flight plan options (see page 61).

3. Load the approach (often while enroute) in anticipation of its future use. This places the

approach in the active flight plan, but retains course guidance in the enroute section until the

approach is activated.

4. Activate the full approach or vectors-to-final, as appropriate. In some scenarios, you may find it

more convenient to immediately activate the approach and skip the Load process outlined above

in step #3. The GNS 430 provides both options.

Approaches with Procedure Turns

The procedure turn portion of an approach is stored as one of the legs of the

approach. For this reason, the GNS 430 requires no special operations from the

pilot — other than flying the procedure turn itself — beyond what is required for

any other type of approach.

This example uses the VOR

Runway 03 approach for Lynchburg

(Virginia) Regional Airport, KLYH,

and assumes a departure from

Frederick (Maryland) Municipal

Airport, KFDK. The steps required to

set up and fly the approach are

detailed below:

1. Prior to departing KFDK, the destination

(KLYH) is selected using the

key or by

creating a flight plan terminating at

Lynchburg Regional.

2. While enroute to KLYH, some 40-50 nautical

miles away, you select the ATIS frequency to

monitor airport conditions and runway usage.

This is accomplished by selecting the NAV-

COM page (see page 39) and selecting the

ATIS frequency from the list. This places the

frequency on standby. Use the

key to

make the ATIS frequency active.

From ATIS you learn that runway 03 is in use and plan your approach accordingly. Press the

key and select the VOR 03 approach using the steps outlined on page 66. From the transitions

window, select LYH VOR (the IAF). Also, select Load? to load (but not activate) the approach.

Load? (or Activate?, if already cleared

for the approach).

3. Within 30 nautical miles of KTOP, the

GNS 430 will switch from enroute mode

to terminal mode and the CDI scale will

transition from 5.0 to 1.0 nautical miles,

full scale deflection.

4. If you havent already activated the

approach (in step #2 above), be sure to

do so when cleared for the approach. See

page 69, step #4 for a description of this

operation.

5. As you approach the IAF (D258G), a

approaches zero, the alert is replaced by

a turn advisory (TURN TO 353°).

6. Follow the arc, keeping the CDI needle centered. When using an autopilot, the course select on the

CDI (or HSI) must be periodically updated with the desired track (DTK) to ensure proper tracking

through the arc. Whenever the course select setting and desired track differ by more than 10°, a

Set course to # # # ° message will appear on the message page.

7. The next point in the approach is an intermediate fix, labeled D025G. As you approach this inter-

Vectors-To-Final

Approach Example

Vectors to Final

Let’s take a second look at the “VOR 22” approach into Billard Municipal. Instead

of following the DME arc, ATC tells you to expect vectors onto the final approach

course. There are several ways to select “vectors to final” with the GNS 430. The first

two options below will normally require the least workload to accomplish:

•

When the approach is first selected, choose “VECTORS” from the transitions

window.

• Load a full approach — including the IAF from the transitions window — as

described on page 66. When cleared, press

and select “Activate Vectors-

To-Final?”. (See page 67.)

• Load the full approach as described on page 66. Use the

key (by pressing

it twice) from the active flight plan page to select the desired leg of the

approach. (See page 65.)

To select “VECTORS” from the transitions window:

1. Select Billard Municipal (KTOP) as your destination, using the

key, or as the last

waypoint in a flight plan.

2. Press the

key and select the VOR 22 approach using the steps outlined on

page 66.

3a. From the transitions window, select VECTORS.

4a. Select Load? (or Activate?, if already cleared for the approach).

To activate vectors-to-final from the procedures page:

1. Select Billard Municipal (KTOP) as your destination, using the

key or as the last

waypoint in a flight plan.

2. Press the

key and select the VOR 22 approach using the steps outlined on

page 66.

5Flying the Vectors Approach

With “vectors to final” selected,

the CDI needle will remain off center

until you’re established on the final

approach course. With the approach

activated, the map page will display

an extension of the final approach

course in magenta (remember,

magenta is used to depict the active

leg of the flight plan) and “VTF” will

appear as part of the active leg on the

default NAV page (as a reminder that

the approach was activated with vec-

tors-to-final). In this example, we’ll

assume ATC vectors result in a rec-

tangular course to intercept final, as

follows:

1. Within 30 nautical miles of KTOP, the

GNS 430 will switch from enroute mode

to terminal mode and the CDI scale will

transition from 5.0 to 1.0 nautical miles,

full scale deflection.

2. If you havent already done so, activate the approach (with vectors-to-final). This allows the GNS

430 to guide you to the final approach course. (See page 79.)

3. ATC instructs you to turn left to a heading of 025°. This places you parallel to the final approach

course in the opposite direction. CDI needle deflection is to the left.

4. ATC instructs you to turn right to a heading of 115°.

5. ATC instructs you to turn right to a heading of 175° to intercept the final approach course. As you

converge with the final approach course the needle moves toward the center. (In the illustration at

left, the needle has not yet returned to the on-screen CDI, since your current position is still 1.7 nm

right of the final approach course.) {continued}

5Course From Fix Flight Plan Legs

Certain approach, departure, and arrival procedures in the Jeppesen database

contain course from fix flight plan legs. The GNS 430 is able to load these legs into

the flight plan along with the rest of the procedure data, and to provide navigation

along these legs.

There are three different types of course from fix legs:

TYPE 1: Course from fix to distance, or Course from fix to DME distance

Course from fix to distance legs will appear in the flight plan like normal way-

points, but the destination

name will always begin

with a "D", followed by a

distance in tenths of nau-

tical miles from the way-

point fix. This example

uses the VOR/DME

RWY 25 approach into

Palmdale, California

(KPMD) and includes a

teardrop course reversal.

1. As you reach the initial approach fix (PMD), a waypoint alert (NEXT DTK 070°) will appear in the

lower right corner of the screen. As the distance to the IAF approaches zero, the alert is replaced

by a turn advisory (TURN TO 070°). Dial the outbound course into the CDI (or HSI) using the

OBS knob and initiate a standard rate turn to this course heading.

2. Fly the outbound course, keeping the CDI needle centered. You are now on the course from fix to

distance leg, as shown on the active flight plan and default NAV pages. Note the magenta line in

the bottom figure, which represents the currently active leg of the approach. The distance (DIS)

displayed on the above screens is TO the D13.0 point. The flight plan will automatically

sequence to the next leg upon reaching D13.0.

3. At 13.0 nm from the FAF, a waypoint alert (NEXT DTK 265°) will appear in the lower right corner

of the screen. Make a standard rate turn to the right to intercept the final approach course and

watch for the CDI needle to begin to center.

Make any necessary course adjustments.

5. Within 2.0 nautical miles of the FAF (THERO), the GNS 430 will switch from terminal mode to

approach mode. (APR will appear in the lower left corner of the screenreplacing TERM.)

CDI scaling will be tightened from 1.0 to 0.3 nautical mile, full scale deflection.

6. As you approach the FAF, NEXT DTK 265° will appear in the lower right corner of the screen.

7. As you cross the FAF, the destination sequences to the MAP (MA25). With the CDI needle cen-

tered, fly toward the MAP, observing the altitude minimums dictated by the approach plate.

8. As you approach the MAP, a waypoint alert (APPRCHING WPT) will appear in the lower right

corner of the screen.

9. As you cross the MAP, SUSP will appear above the

key, indicating that automatic

sequencing of approach waypoints is suspended at the MAP. If a missed approach is required,

use the

key to initiate the missed approach sequence, as outlined below.

TYPE 2: Course from fix to altitude

Course from fix to altitude legs will show the specific target altitude on the

active flight plan and default NAV pages. The missed approach sequence for the

Palmdale VOR/DME RWY 25 approach includes a course from fix to altitude leg.

In this instance, the leg corresponds to the initial phase of the missed approach,

which reads “Climb to 5000’ outbound via PMD VOR R-282”.

After crossing the MAP, press the

key. The missed approach sequence is automatically

offered, starting with the course from fix to altitude leg. The NEXT DTK 282° alert appears in the

lower right corner of the screen. Follow the missed approach procedures, as published on your

approach plate, for proper climb and heading instructions.

2. Note that within a few seconds of pressing

to release suspend mode and start the

approach sequence, SUSP re-appears above the

key as the GNS 430 returns to sus-

pend mode. This is normal when flying a course from fix to altitude leg and indicates that auto-

matic leg sequencing is suspended.

5ILS Approaches

Precision approaches can be performed with the GNS 430's built-in VLOC

(VOR/localizer/glideslope) receivers. The GPS receiver can be used for guidance

prior to reaching the final approach fix, but once there, the proper frequency must

be selected on the VLOC window (left side of screen) and the CDI output set to

"VLOC".

The GNS 430 can be set to automatically switch the external CDI output from

GPS to VLOC as you intercept the final approach course. When the ILS approach

is activated, the GNS 430 will automatically switch within 1.2 nautical miles left or

right of the final approach course. This switch can take place anywhere from 2.0 to

15.0 nautical miles from the FAF.

The illustration at left shows multiple locations along the approach path and

which CDI selection you can expect: GPS or VLOC. Within the area of the shaded

box, the automatic switch from GPS to VLOC should occur.

The automatic switch from GPS to VLOC is not immediate, but instead occurs

gradually to prevent abrupt CDI changes when coupled to an autopilot. The CDI

selection can also be changed manually by pressing the

key. Once the

switch from GPS to VLOC has occurred, either automatically or manually, it will

not automatically switch again until the approach is reactivated or another

approach is selected. To prevent automatic ILS CDI selection, choose the "Manual"

ILS CDI setting, as described on page 155. (The factory default setting is "Auto",

which enables the automatic switch to VLOC.)

1. Within 30 nautical miles of KFLG, the

GNS 430 will switch from enroute

mode to terminal mode and the CDI

scale will transition from 5.0 to 1.0

nautical miles, full scale deflection.

2. If you havent already activated the approach (in steps on previous page), be sure to do so when

cleared for the approach. See page 69, step #4 for a description of this operation.

3. As you approach the IAF (SHUTR), a waypoint alert (NEXT DTK 030°) will appear in the lower

Points to Remember for ALL Approaches

• The GNS 430 is designed to complement your printed approach plates and

vastly improve situational awareness throughout the approach. However, you

must always fly an approach as it appears on the approach plate.

• The active leg (or the portion of the approach currently in use) is depicted in

magenta on the Map Page. As you fly the approach, the GNS 430 will automati-

cally sequence through each leg of the approach unless "SUSP" appears above

the OBS key. "SUSP" indicates that automatic sequencing of approach way-

points is suspended on the current leg and normally appears at holding patterns

and upon crossing the missed approach point (MAP).

Points to Remember for Localizer-based Approaches

• The default factory setting will allow the CDI output to automatically switch

from the GPS receiver to the VLOC receiver. If the "ILS CDI Capture" setting

is changed to "Manual", you must determine when to select "GPS" or "VLOC"

guidance during the approach. Remember, "VLOC" is required for the final

course segment from final approach fix (FAF) to MAP.

• If the CDI output has not automatically switched from GPS to ILS by 2.0 nauti-

cal miles prior to the FAF, you must manually switch to the VLOC receiver by

pressing

. Verify that "VLOC" is displayed directly above the

key.

• Automatic switching of CDI output is available for ILS, localizer, SDF and

LDA approaches. Automatic CDI switching is not available for backcourse

approaches.

• When flying an approach with the autopilot coupled, you must monitor system

functions at all times and verify that the autopilot and external CDI (or HSI)

switches to the VLOC receiver with sufficient time to capture and track the

approach course. Switching to "VLOC" late in the approach may not provide

the autopilot enough time to respond and intercept the approach course prior to

the FAF (depending upon the performance characteristics of your autopilot and

aircraft). In such cases, you should manually fly the approach or refer to the

documentation provided with your autopilot. 91

430MANF.qxd 7/24/00 4:44 PM Page 91

• When an ILS approach is first selected and "loaded" (or "activated"), the ILS

frequency is automatically placed in the standby field. In order to fly the final

course segment of the ILS approach, you must place the ILS frequency in the

active frequency field by pressing

. If you forget to do this, a "Select appro-

priate frequency for approach" message will appear within 3.0 nautical miles

of the FAF.

• When flying a localizer-based approach (other than backcourse) with automat-

ic CDI switching enabled:

1. "GPS" guidance is used while flying outbound and on the initial portion of the procedure

turn.

2. "VLOC" guidance is used on the remainder of the approach from the time you turn

inbound on the procedure turn.

3. The localizer frequency must be active to use "VLOC" guidance.

• When flying a localizer-based approach with automatic CDI switching disabled:

1. You may select "VLOC" guidance at any point on the approach prior to reaching the

FAF.

2. The localizer frequency must be active to use "VLOC" guidance.

provides information for the thousands of airports, VORs, NDBs, intersections, run-

ways, frequencies and procedures stored on your Jeppesen NavData® card. A WPT

page is also provided to display information for up to 1,000 user-created waypoints.

To quickly select a WPT page:

1. From any page, press and hold

Please note that your GNS 430 uses ICAO

identifiers for all airports. All U.S. airport

identifiers which contain only letters use the

prefix ‘K’. For example, Los Angeles

International is KLAX under the ICAO stan-

dard. Other airports, such as Otten Memorial

(3VS), that contain numbers in the identifier,

do not require the ‘K’ prefix. Many foreign

countries use two letter prefixes. For more

NOTE

Not all approaches in the database are approved for GPS use. As

you select an approach, a “GPS” designation to the right of the pro-

cedure name indicates the procedure can be flown using the GPS

receiver. Some procedures will not have this designation, meaning

the GPS receiver may be used for supplemental navigation guidance

only. ILS approaches, for example, must be flown by tuning the

VLOC receiver to the proper frequency and coupling the VLOC

receiver to the external CDI (or HSI).

NOTE

The GNS 430 allows you to create a new user waypoint at a defined radial

and distance from your present position. To reference your present position,

follow the steps above, but press

in step #4. “P.POS” will appear in

the reference waypoint (REF WPT) field to indicate that radial and dis-

tance information will reference your present position.

The second reference waypoint field (REF WPT) is a temporary reference

only—not a reference that will be stored with the user waypoint. By

default, this field will display a radial from the nearest VOR. However, you

can select any waypoint—by identifier—to use as a reference in this field.

Your GNS 430 can store user-defined waypoints which are generated

from other equipment in your panel. For example, an EFIS equipped

with joystick inputs can be used to create user waypoints which will (if

your installation supports this) automatically transfer to your GNS 430.

Nearest Airspace Page

The last page in the NRST group, the nearest airspace page, will alert you to as

many as nine controlled or special use airspaces near or in your flight path. Alerts are

provided according to the following conditions:

• If your projected course will take you inside an airspace within the

next ten minutes, the alert message “Airspace ahead -- less than 10

minutes” will appear. The nearest airspace page will show the airspace

as “Ahead”.

• If you are within two nautical miles of an airspace and your current

course will take you inside, the message “Airspace near and ahead”

will appear. The nearest airspace page will show “Within 2nm of

airspace”.

• If you are within two nautical miles of an airspace and your current

course will not take you inside, the message “Near airspace less than

2nm” will appear. The nearest airspace page will show the airspace as

“Ahead < 2nm”.

• If you have entered an airspace, the message “Inside Airspace” will

appear. The nearest airspace page will show “Inside of airspace”.

Note that the airspace alerts are based on three-dimensional data (latitude, longi-

tude and altitude) to avoid nuisance alerts. The alert boundaries for controlled air-

space are also sectorized to provide complete information on any nearby airspace.

Once one of the described conditions exists, the message annunciator will flash, alert-

Trip Planning— allows the pilot to view desired track (DTK), distance (DIS),

estimated time en route (ETE), enroute safe altitude (ESA) and estimated time

of arrival (ETA) information for a direct-to, point-to-point between two specified

waypoints or for any programmed flight plan.

Density Alt / TAS / Winds— indicates the theoretical altitude at which your air-

craft will perform depending upon several environmental conditions, including

indicated altitude (IND ALT), barometric pressure (BARO) and total air temper-

ature (TAT; the temperature, including the heating effect of speed, read on a

standard outside temperature gauge). This menu option computes true airspeed

(TAS), based upon the factors above and the calibrated airspeed (CAS). Also, this

menu option determines winds aloft—the wind direction and speed—and a

head wind/tail wind component, based upon the calculated density altitude

(DEN ALT), true airspeed, aircraft heading (HDG) and ground speed.

Crossfill— allows the pilot to transfer the active flight plan, any stored flight

plan, a user waypoint or all user waypoints between two 400-Series GARMIN

units (GNS 430/GNC 420/GPS 400) in a dual-unit installation.

Scheduler— displays reminder messages (such as “Change oil”, “Switch fuel

tanks”, “Overhaul”, etc.). One-time, periodic, and event-based messages are

allowed. One-time messages will appear once the timer expires and will reap-

pear each time the GNS 430 is powered on, until the message is deleted.

Periodic messages will automatically reset to the original timer value, once the

message is displayed. Event-based messages do not use a timer, but rather a

specific date and time. 137

RAIM Prediction—

predicts if GPS coverage is available for your current loca-

tion or at a specified waypoint at any time and date. Receiver Autonomous

Integrity Monitoring performs checks to ensure that the GNS 430 will have ade-

quate satellite geometry during your flight. RAIM availability will be near 100%

in Oceanic, En route and Terminal phases of flight. Because the FAA’s TSO

requirements for non-precision approaches specify significantly better satellite

coverage than other flight phases, RAIM may not be available when flying some

approaches. The GNS 430 will automatically monitor RAIM during approach

operations and warn you if RAIM is not available. In such cases, use the GNS

430’s VLOC receiver instead for many of the non-precision and precision

approaches stored on your Jeppesen NavData® card. RAIM prediction will help

you plan for a pending flight to confirm GPS operation during an approach.

Sunrise / Sunset—

allows you to calculate the time of sunrise and sunset at any

waypoint or your present position for a specified date.

Software / Database Ver.—

provides software version information for the oper-

ating software within the GPS receiver, COM transceiver, VOR/localizer receiver,

glideslope receiver and main processor board. The software / database version

Setup 1 Page

The setup 1 page provides access (via “menu options”) to airspace alarms, CDI

scale adjustment, an arrival alarm, units of measure settings, position formats, map

datums and settings for local or UTC time display. When a menu option is selected,

the corresponding page will appear providing access to the various unit settings.

To select a menu option from the setup 1 page:

1. Press the small right knob (

) momentarily, to activate the flashing cursor.

2. Rotate the large right knob (

) to select the desired menu option, and press

The following menu options are available:

Airspace Alarms—

allows you to turn the controlled / special-use airspace mes-

sage alerts on or off. This will not affect the alerts listed on the nearest airspace

page or the airspace boundaries depicted on the map page. It will simply turn

on/off the warning provided when you are approaching or near an airspace.

An altitude buffer is also provided which “expands” the vertical range above or

below an airspace. For example, if the buffer is set at 500 feet, and you are more

than 500 feet above or below an airspace, you will not be notified with an alert

message; if you are less than 500 feet above or below an airspace and projected to

enter it, you will be notified with an alert message. The default is 200 feet.

CDI / Alarms—

allows you to define the scale for the GNS 430’s on-screen course devia-

tion indicator. The scale values represent full scale deflection for the CDI to either side.

The default setting is “5.0 nm”. At this setting, the CDI scale is set to 5 nm during the

enroute phase of flight. Within 30 nm of your destination airport the CDI scale gradually

ramps down to 1.0 nm (terminal area). Likewise when leaving your departure airport the

CDI scale is set to 1.0 nm and gradually ramps UP to 5 nm beyond 30 nm (from the

departure airport).

During approach operations the CDI scale gradually ramps down even further, to 0.3 nm.

This transition normally occurs within 2.0 nm of the final approach fix (FAF). If a lower

CDI scale setting is selected (i.e., 1.0 nm or 0.3 nm) the higher scale settings will not be

selected during ANY phase of flight. For example, if 1.0 nm is selected, the GNS 430 will

use this for the enroute and terminal phase and ramp down to 0.3 nm during an

approach. Note that the Receiver Autonomous Integrity Monitoring (RAIM) protection

limits listed below follow the selected CDI scale and corresponding modes:

CDI Scale RAIM Protection

+/-5.0 nm or Auto (en route) 2.0 nm

+/-1.0 nm or Auto (terminal) 1.0 nm

+/-0.3 nm or Auto (approach) 0.3 nm

An “auto” ILS CDI selection allows the GNS 430 to automatically switch the external

CDI from the GPS receiver to the VLOC receiver, when established on the final

approach course. (See page 86.) Or, select “manual” to manually switch the external CDI

connection, as needed.

An arrival alarm, provided on the CDI / alarms page, may be set to notify you with a mes-

sage when you have reached a user-defined distance to the final destination (the direct-to

waypoint or the last waypoint in a flight plan). Once you have reached the set distance

(up to 99.9 units), an “Arrival at [waypoint]” message will be displayed.

Units / Mag Var—

allows you to configure the displayed data to standard or metric units

of measure. This setting applies to distance, speed, altitude, fuel, pressure and tempera-

ture. Also provides three magnetic variation (heading) options: True, Auto or User-

defined. If “Auto” is selected, all track, course and heading information will be corrected

to the magnetic variation computed by the GPS receiver. The “True” setting will refer-

ence all information to true north, and the “User” setting will correct information to an

user-entered value.

430MANF.qxd 7/24/00 4:44 PM Page 153

Position / Map Datum— configures position readout information to the desired

position format and datum. The NavData® card contains over 100 map datums

to adjust your position reading, making it conform to specific paper charts. If

you are using a chart based on another datum, you must set the GNS 430 to use

the same datum. Using a map datum that does not match the charts you are

using can result in significant differences in position information. If you are

using the paper charts for reference only, the GNS 430 will still provide correct

navigation guidance to the waypoints contained in the database, regardless of

the datum selected.

Date / Time—

provides settings for time format (local or UTC; 12- or 24-hour)

and time offset. The time offset is used to define current local time. UTC (also

called “GMT” or “zulu”) date and time are calculated directly from the GPS

satellites’ signals and cannot be changed. If you prefer to use local time, simply

designate the offset by adding or subtracting the correct number of hours.

Messages

The GNS 430 uses a flashing “MSG” annunciator at the bottom of

the screen (directly above the

key) to alert you of any important

information or warnings. While most messages are advisory in

nature, warning messages may require your intervention.

Whenever the “MSG” annunciator flashes, press the

key to

display the message. Press

again to return to the previous page.

The following is a list of available messages and their meanings:

Airspace ahead -- less than 10 minutes—Your GPS-calculated

course is projected to enter a special use airspace within 10 minutes.

This message is automatically disabled within 30 nautical miles of an

arrival airport, when an approach is loaded.

Airspace near and ahead—Your GPS-calculated position is within

2 nautical miles of the boundary of a special use airspace and your

course is projected to enter the airspace within 10 minutes. This

message is automatically disabled within 30 nautical miles of an

arrival airport, when an approach is loaded.

Altitude input failure—The GNS 430 is configured to receive

altitude serializer data (Icarus, Rosetta or Shadin) and it is not being

received. Or, the data was being received, but has been interrupted.

If a grey code altitude input is available, it will be used instead. If

the problem persists, contact your GARMIN dealer and check the

installation and installation settings. When this message occurs, no

pilot action is required if enough satellites are available for a 3D

position fix (provided no RAIM warnings are present). However, if

only a 2D position fix is possible, the pilot should maintain the GPS

altitude within 1,000 feet of pressure altitude—by entering the

altitude on the position page.

Approach is not active—The approach could not transition to

“active”, at 2 nautical miles or closer to the FAF. Verify that “SUSP”

DOES NOT appear directly above the

key, indicating the auto

waypoint sequencing is suspended. This message also appears if

Receiver Autonomous Integrity Monitoring (RAIM) has determined

that sufficient GPS satellite coverage DOES NOT exist for the phase

of flight you are currently in (along with a “RAIM not available from

FAF to MAP” message).

Approaching target altitude—

The current GPS-computed alti-

tude is within 500 feet of the final Vertical Navigation target altitude.

Approaching VNAV profile—You are within one minute of reach-

ing the initial Vertical Navigation descent, or climb, point.

Check unit cooling—The GNS 430 has detected excessive display

backlighting temperature. The backlighting has been automatically

dimmed to reduce the temperature. Check for adequate ventilation or

check cooling air flow. Contact your GARMIN dealer for assistance.

COM has failed—The GNS 430 has detected a failure in its com-

munications transceiver. The COM transceiver is not available and

the unit should be returned to your GARMIN dealer for service.

COM is not responding—Internal system-to-system communica-

tion between the main processor and the COM transceiver has

failed. Operational status of the COM transceiver is unknown and

the unit should be returned to your GARMIN dealer for service.

COM needs service—The GNS 430 has detected a failure in its

COM transmitter power has been reduced—The GNS 430 has

detected excessive unit temperature and/or an insufficient voltage

level. The COM transceiver transmit power has been automatically

reduced to compensate for the condition. For excessive temperatures,

check for adequate ventilation or

check cooling air flow. If the mes-

sage persists, contact your GARMIN dealer for assistance.

Data card failure—The GNS 430 has detected a problem with the

NavData® card. The data is not usable and the card should be

returned to Jeppesen or your GARMIN dealer.

Data transfer cancelled (crossfill is busy)—An attempt to trans-

fer flight plan data during a unit-to-unit crossfill was cancelled. The

host unit is busy or unable to communicate. Wait until any previous

crossfill operation is complete, before re-attempting the transfer.

Data transfer cancelled (data invalid)—An attempt to transfer a

single user waypoint during a unit-to-unit crossfill was cancelled. No

waypoint was specified on the crossfill page. Select a user waypoint

and re-attempt the transfer.

Data transfer cancelled (version mismatch)—An attempt to

transfer data during a unit-to-unit crossfill was cancelled. The

database versions of the two GNS 430s are not identical. If

necessary, update the database(s) so they match. Contact Jeppesen or

your GARMIN dealer for assistance.

Data transfer error, please re-transmit—An error was detected

during unit-to-unit crossfill of user data (user waypoints and/or flight

plans). The data transfer should be re-attempted.

Data transfer is complete—The unit-to-unit crossfill of user

waypoint data has finished.

Database changed, validate user modified procedures—You

have modified one or more approaches, departures or arrivals from

their original published form. When the NavData® card is replaced

(database update), you must manually verify your changes in the new

database. This message will occur each time a flight plan containing a

modified procedure (generated from a prior database version) is acti-

vated. To eliminate the message, re-create the flight plan from the

new database, then make the desired modifications.

Degraded accuracy—GPS position accuracy has been degraded

and RAIM is not available. Poor satellite geometry (or coverage) has

resulted in a horizontal DOP greater than 4.0. Additional cross-

checking using another navigation source is required to verify the

integrity of the GPS position.

Display backlight failure—The GNS 430 has detected a failure in

the display backlighting. The unit should be taken to your GARMIN

FPL has been truncated—The flight plan (FPL) was truncated

because not enough room existed to insert an approach, departure or

arrival. This may occur upon power up when a database change

increases the number of waypoints within an instrument procedure.

FPL is full - remove unnecessary waypoints—An attempt has

been made to add more than 31 waypoints to a flight plan (FPL).

The GNS 430 will not allow more than 31 waypoints per flight plan.

FPL leg will not be smoothed—The upcoming flight plan (FPL)

leg is too short for smooth waypoint transitions. Expect a rapid

change in the CDI.

FPL waypoint is locked—At least one flight plan (FPL) waypoint

is locked because the waypoint has been removed from the current

NavData® card (database change), the data card is missing, or the

data card has failed.

FPL waypoint moved—The position data for one or more flight

plan (FPL) waypoints moved at least 0.33 arc minutes in the current

NavData® card (database change).

FPL waypoint was deleted—At least one flight plan (FPL) way-

point is no longer available when a new NavData® card was

installed (database change).

Heading input failure—The heading selection on the external

HSI’s (or CDI’s) OBS course selector cannot be read properly. Your

GARMIN dealer may need to check the installation.

Inside airspace—Your GPS-calculated position lies within the

boundaries of a special use airspace. This message is automatically

disabled within 30 nautical miles of an arrival airport, when an

approach is loaded.

Invalid closest pt of FPL—A closest point cannot be created from

the waypoint entered on the “Closest point of flight plan” window.

This occurs when the selected waypoint is beyond the limits of all

legs in the flight plan, too far away, or when a unique waypoint name

for the closest point cannot be created.

Invalid FPL modification—An attempt was made to modify the

final course segment (FAF to MAP) of an instrument approach. The

GNS 430 will not allow the modifications.

Invalid waypoint ident—An attempt was made to create a user

waypoint with an invalid name. The GNS 430 will not allow spaces

between characters in the waypoint name.

MAIN processor requires service—The GNS 430 has detected a

failure in the main system processor. The GNS 430 is not usable and

should be taken to your GARMIN dealer for service.

Memory battery low—The internal battery that sustains user

memory is low and should be replaced by a GARMIN dealer as soon

as possible. Failure to do so may result in loss of stored data, includ-

ing flight plans, user waypoints, unit settings and satellite data.

Near airspace -- less than 2 nm—Your GPS-calculated position is

within 2 nautical miles of a special use airspace boundary, but you

are not projected to enter the airspace. This message is automatically

disabled within 30 nautical miles of an arrival airport, when an

approach is loaded.

Need altitude - display position page—The GPS receiver needs

altitude input in order to start and/or continue 2D navigation. Select

the position page and verify the altitude reading. If the altitude is in

error by more than 500 feet, enter the current altitude as accurately

as possible. An inaccurate altitude will directly translate into inaccu-

rate position information.

No altitude input is being received—No altitude data is being

received from RS-232 (Serializer: Icarus, Rosetta or Shadin) or grey

code inputs. If the problem persists, contact your GARMIN dealer

and check the installation and installation settings. When this mes-

sage occurs, no pilot action is required if enough satellites are avail-

able for a 3D position fix (provided no RAIM warnings are present).

However, if only a 2D position fix is possible, the pilot should main-

tain the GPS altitude within 1,000 feet of pressure altitude—by

entering the altitude on the position page.167

confirmation page. If the NavData card is removed during operation, a “Data card

removed-Unit will restart in 30 seconds” warning. A counter will begin to count

down and, if the card is not replaced within 30 seconds, the GNS 430 will automati-

cally reinitialize. You may also reinitialize the unit manually by pressing

To insert the NavData card:

1a. Place the card into the NavData card slot, with the label facing to the left and the swing

arm handle at the bottom front.

2a. Press the NavData card into place until it seats on the internal connector and the front of

the card is flush with the face of the GNS 430 unit.

3a. If the swing arm handle is up, gently lower the handle and push it into placeflush with

the face of the GNS 430 unit.

To remove the NavData card:

1b. Gently press on the tabusing a slight upward motionat the front center of the

NavData card. This will partially deploy the swing arm handle.

2b. Rotate the swing arm handle upward (and outward) until it locks into place, perpendicular

to the face of the GNS 430 unit.

3b. Grasp the top and bottom surfaces of the swing arm handle, between your thumb and

forefinger, and pull directly away from the face of the GNS 430 unit to unseat the con-

nector and remove the NavData card. 177

Appendix D: Troubleshooting Q & A

This section is designed to answer some of the common questions regarding the GNS 430’s

capabilities and operation. If you have a problem operating the unit, read through this appendix

and refer to the reference section noted. If you don’t find answers to your particular question here,

use the index to find the appropriate section elsewhere in this manual. If, after reading through the

appropriate reference section, you still haven’t found the answer to your question, please see your

authorized dealer or contact GARMIN directly at the address or phone numbers listed on page iv.

GARMIN is dedicated to supporting its products and customers.

What is RAIM, and how does it affect approach operations?

RAIM is an acronym for Receiver Autonomous Integrity Monitoring, a GPS receiver function that performs a consistency check on all

tracked satellites. RAIM ensures that the available satellite geometry will allow the receiver to calculate a position within a specified protection

limit (2 nautical miles for oceanic and en route, 1 nm for terminal and 0.3 nm for non-precision approaches).

During oceanic, en route and terminal phases of flight, RAIM will be available nearly 100% of the time. Because of the tighter protection

limit on approaches, there may be times when RAIM is not available. The GNS 430 automatically monitors RAIM and will warn you with an

alert message (see Section 10) when it is not available, and the INTEG annunciator ( ) will appear at the bottom left corner of the

screen. If RAIM is not available when crossing the FAF, the pilot must fly the missed approach procedure. The GNS 430’s RAIM prediction

function (see page 146) will also allow you to see whether RAIM will be available for a specified date and time.

181

TROUBLE-

SHOOTING

APPENDIX

NOTE

If RAIM is not predicted to be available for the final approach course, the approach will not become active—as indicated by an

“Approach is not active” message, a “RAIM not available from FAF to MAP” message and the INTEG annunciator.

430MANF.qxd 7/24/00 4:44 PM Page 181

Why arent there any approaches

available for my flight plan?

Approaches are available for the final destination

airport in a flight plan or as a direct-to (keep in

mind that some VOR/VORTAC identifiers are simi-

lar to airport identifiers). If a destination airport

does not have a GPS approach, the GNS 430 will

indicate “NONE” for the available procedures—as

listed on the airport approach page. For more information on selecting an approach, see page 66.

What happens when I select an approach? Can I store a flight plan with an approach, departure or arrival?

Whenever you load an approach, departure or arrival into the active flight plan, a set of

approach, departure or arrival waypoints is inserted into the flight plan—along with a header line

describing the instrument procedure you selected. The original en route portion of the flight plan

will remain active, unless you “Activate” the instrument procedure; which may be done when the

procedure is loaded or at a later time.

Flight plans can also be stored with an approach, departure or arrival. Keep in mind that

the active flight plan is erased when the unit is turned off and overwritten when another flight

plan is activated. When storing flight plans with an approach, departure or arrival, the GNS 430 will use the waypoint information from the

current database to define the waypoints. If the database is changed or updated, the GNS 430 will automatically update the information if the

procedure has not been modified. If an approach, departure or arrival procedure is no longer available, the flight plan will become locked until

the procedure is deleted from the flight plan or the correct database is installed. For information on loading an approach, departure or arrival,

see page 66. See page 57 for instructions on saving and copying flight plans.

Can I file slant Golf (/G) using my GPS?

Yes, you may file your flight plan as /G if your GNS 430 is a certified A1 or A2 installation. If you are flying en route, you may fly /G with an

expired database only after you have verified all route waypoints. Non-precision approaches may not be flown with an expired database. See

your approved Airplane Flight Manual Supplement for more information.

430MANF.qxd 7/24/00 4:44 PM Page 182

What does the

key do and when do I use it?

The

key is used to select manual (OBS mode) or automatic sequencing of waypoints.

Activating OBS mode (as indicated by an annunciation directly above the

key)

holds your current ‘active to’ waypoint as your navigation reference and prevents the GPS from

sequencing to the next waypoint. When OBS mode is cancelled, automatic waypoint sequencing is

selected, and the GNS 430 will automatically select the next waypoint in the flight plan once the

aircraft has crossed the present active-to waypoint.

NORMAL (no “OBS” annunciator) OBS

Automatic sequencing of waypoints Manual sequencing- ‘holds’ on selected waypoint

Change in HSI does not affect CDI deflection Manually select course to next waypoint from HSI

Always navigates ‘TO’ the active waypoint Will indicate ‘TO’ or ‘FROM’ waypoint

Must be in this mode for final approach course Cannot be set for final approach course or published holding patterns

Whenever OBS mode is active, the GNS 430 allows you to select the desired course to/from a waypoint using the HSI (much like a VOR) and

display a to/from flag for the active-to waypoint. If an external course input is not available, you may select the OBS course on-screen, via a “Select

OBS Course pop-up window. With OBS mode cancelled, the CDI will always display a ‘TO’ indication for the next waypoint once you’ve crossed

the active waypoint (provided the active waypoint is not the last waypoint). Refer to page 72 for an example using the

key.

One application for the

key is holding patterns. The

key is used to suspend waypoint sequencing and select the desired course along

the waypoint side of the hold. For many approach operations, setting and resetting of waypoint sequencing is automatic. Holding patterns that are

part of an approach will automatically disable waypoint sequencing, then re-enable waypoint sequenc-

ing after one time around the holding pattern. A “SUSP” annunciation will appear directly above the

key (see illustration left) to indicate that automatic waypoint sequencing is temporarily suspend-

ed and course selection is not available. If more than one trip around the holding pattern is desired,

press the

key to again suspend waypoint sequencing. An example of this operation is an

approach which begins with a

holding pattern at the initial approach fix (IAF). See page 73 for more

information on the “SUSP” annunciation and approaches with holding patterns.

SHOOTING

APPENDIX

430MANF.qxd 7/24/00 4:44 PM Page 183

When should I use the

key to

return to auto sequencing, and what

happens when I do?

The most common application for using the

key is the missed approach. The GNS 430 will sus-

pend automatic waypoint sequencing (indicated by

a “SUSP” annunciation directly above the

key;

see right) when you cross the missed approach point

(MAP). This prevents the GNS 430 from automatically sequencing to the missed approach holding

point (MAHP). If a missed approach is required, press the

key to return to automatic way-

point sequencing and sequence the approach to the MAHP. See page 72 for more information on missed approaches.

Why wont my unit automatically sequence to the next waypoint?

The GNS 430 will only sequence flight plan waypoints when automatic sequencing is enabled (i.e., no “OBS” or “SUSP” annunciation

directly above the

key). For automatic sequencing to occur, you must also cross the “bisector” of the turn you are navigating. The bisector

is a perpendicular line between two flight plan legs which crosses through the waypoint common to both legs.

How do I skip a waypoint in an approach, departure or arrival?

The GNS 430 allows you to manually select any approach, departure or arrival leg as the

active leg of your flight plan. This procedure is performed from the active flight plan page by

highlighting the desired waypoint and pressing

twice, then

to approve the selection

(see illustration right). The GPS will then provide navigation along the selected flight plan leg, so

be sure you have clearance to that position. See page 65 for more information.

How do I fly the GPS with an autopilot and DG heading bug?

If you do not have an HSI, you should make your course selections on the external CDI’s OBS knob and the DG heading bug.

APPENDIX

430MANF.qxd 7/24/00 4:44 PM Page 184

When does turn anticipation begin, and what bank angle is expected?

The GNS 430 will smooth adjacent leg transitions based upon a nominal 15º bank angle (with

the ability to roll up to 25º) and provide three pilot cues for turn anticipation: 1) A waypoint alert

(“NEXT DTK ###°”) will flash in the lower right corner of the screen 10 seconds before the turn

point. 2) A flashing turn advisory (“TURN TO

###°”) will appear in the lower right corner of the

screen when you are to begin the turn. Set the HSI

to the next DTK value and begin the turn. 3) The

To/From indicator on the HSI (or CDI) will flip

momentarily to indicate that you have crossed the

midpoint of the turn. For more information on waypoint alerts and turn advisories, see section 5.

When does the CDI scale change, and what does it change to?

The GNS 430 will begin a smooth CDI scale transition from the 5.0 nm (enroute mode) to the 1.0 nm (ter-

minal mode) scale 30 nm from the destination airport (see left). The CDI scale will further transition to 0.3

nm (approach mode) at 2 nm prior to the FAF during an active approach. If you are in a missed approach

situation, and would like to return the CDI to the 1 nm scale, activate the

missed approach sequence by pressing the

key, as described on

page 72. The CDI scale will also be 1.0 nm (terminal mode) within

30 nm of the departure airport.

Why does my CDI not respond like a VOR when OBS

mode is active?

Unlike a VOR, the CDI scale used on GPS equipment is based on the

cross-track distance to the desired course, not an angular relationship to

the destination (see right). Therefore, the CDI deflection on the GPS will

be constant regardless of the distance to the destination, and will not

become less sensitive when you are further away from the destination.

For more information on the CDI scale, see page 153.

What is the correct missed approach procedure? How do I select the

missed approach holding point?

To comply with TSO specifications, the GNS 430 will not automatically sequence past the

MAP. The active-to waypoint will sequence to the first waypoint in the missed approach proce-

dure, whenever the

key is pressed AFTER crossing the MAP. All published missed

approach procedures must be followed, as indicated on the approach plate.

To execute the missed approach procedure prior to the MAP (not recommended), select the

active flight plan page and use the

key (by pressing it twice) to activate the missed approach

portion of the procedure, as described on page 65.

How do I re-select the same approach or activate a new approach after a missed approach?

After flying all missed approach procedures, you may reactivate the same approach for another attempt from the procedures page. Once you

have been given clearance for another attempt, activate the approach from the procedures page by highlighting “Activate Approach?” and then

pressing

. The GNS 430 will provide navigation along the desired course

to the waypoint and rejoin the approach in sequence from that

point on. See page 65 for information on activating a specific flight plan leg.

To activate a new approach for the same airport, select the new procedure from the procedures page. To view the procedures page, press

and rotate the large right knob (

) to highlight “Select Approach?”. Press

and rotate the large right knob (

) to highlight the new

approach you want to fly. Press

to select the approach, then select the desired transition. Finally, highlight “Activate?” at the bottom right

corner of the screen and press

to activate the new approach.

To activate a new approach to a different airport, press

and select the desired airport using the small (

) and large (

) right knobs.

Press

to accept the selected airport, then follow the steps in the preceding paragraph to select an approach for the new airport. See sec-

tion 5 for more information on selecting and activating approaches.
