WARNING: Navigation and terrain separation must NOT be predicated

upon the use of the terrain function. The GTN 725/750 Terrain Proximity

feature is NOT intended to be used as a primary reference for terrain

avoidance and does not relieve the pilot from the responsibility of being

aware of surroundings during ﬂight. The Terrain Proximity feature is only

to be used as an aid for terrain avoidance and is not certiﬁed for use in

applications requiring a certiﬁed terrain awareness system. Terrain data

is obtained from third party sources. Garmin is not able to independently

verify the accuracy of the terrain data.

WARNING: The displayed minimum safe altitudes (MSAs) are only advisory

in nature and should not be relied upon as the sole source of obstacle and

terrain avoidance information. Always refer to current aeronautical charts

for appropriate minimum clearance altitudes.

WARNING: The Garmin GTN 725/750 has a very high degree of functional

integrity. However, the pilot must recognize that providing monitoring

and/or self-test capability for all conceivable system failures is not

practical. Although unlikely, it may be possible for erroneous operation

to occur without a fault indication shown by the GTN 725/750. It is thus

the responsibility of the pilot to detect such an occurrence by means of

cross-checking with all redundant or correlated information available in

the cockpit.

WARNING: The altitude calculated by GPS receivers is geometric height

above Mean Sea Level and could vary signiﬁcantly from the altitude

displayed by pressure altimeters, such as the output from the GDC 74A/B

Air Data Computer, or other altimeters in aircraft. GPS altitude should never

be used for vertical navigation. Always use pressure altitude displayed by

pressure altimeters in the aircraft.

WARNING: Do not use outdated database information. Databases used

in the GTN 725/750 system must be updated regularly in order to ensure

that the information remains current. Pilots using an outdated database

do so entirely at their own risk.

WARNING: Do not use basemap (land and water data) information for

primary navigation. Basemap data is intended only to supplement other

approved navigation data sources and should be considered as an aid to

enhance situational awareness.

WARNING: Trafﬁc information shown on the GTN 725/750 is provided as

an aid in visually acquiring trafﬁc. Pilots must maneuver the aircraft based

only upon ATC guidance or positive visual acquisition of conﬂicting trafﬁc.

WARNING: Do not use data link weather information for maneuvering in,

near, or around areas of hazardous weather. Information contained within

data link weather products may not accurately depict current weather

conditions.

WARNING: Do not use the indicated data link weather product age to

determine the age of the weather information shown by the data link

weather product. Due to time delays inherent in gathering and processing

weather data for data link transmission, the weather information shown by

the data link weather product may be signiﬁcantly older than the indicated

weather product age.

WARNING: For safety reasons, GTN 725/750 operational procedures must

be learned on the ground.

WARNING: To reduce the risk of unsafe operation, carefully review and

understand all aspects of the GTN 725/750 Pilot’s Guide. Thoroughly

practice basic operation prior to actual use. During ﬂight operations,

carefully compare indications from the GTN 725/750 to all available

navigation sources, including the information from other NAVAIDs, visual

sightings, charts, etc. For safety purposes, always resolve any discrepancies

before continuing navigation.

CAUTION: The United States government operates the Global Positioning

System and is solely responsible for its accuracy and maintenance. The

GPS system is subject to changes which could affect the accuracy and

performance of all GPS equipment. Portions of the Garmin GTN 725/750

utilize GPS as a precision electronic NAVigation AID (NAVAID). Therefore,

as with all NAVAIDs, information presented by the GTN 725/750 can be

misused or misinterpreted and, therefore, become unsafe.

CAUTION: The Garmin GTN 725/750 does not contain any user-serviceable

parts. Repairs should only be made by an authorized Garmin service center.

Unauthorized repairs or modiﬁcations could void both the warranty and

the pilot’s authority to operate this device under FAA/FCC regulations.

CAUTION: The GTN displays use a lens coated with a special anti-reﬂective

coating that is very sensitive to skin oils, waxes, and abrasive cleaners.

CLEANERS CONTAINING AMMONIA WILL HARM THE ANTI-REFLECTIVE

COATING. It is very important to clean the lens using a clean, lint-free cloth and

an eyeglass lens cleaner that is speciﬁed as safe for anti-reﬂective coatings.

NOTE: Do not rely solely upon data link services to provide Temporary Flight

Restriction (TFR) information. Always conﬁrm TFR information through

ofﬁcial sources such as Flight Service Stations or Air Trafﬁc Control.

NOTE: All visual depictions contained within this document, including

screen images of the GTN bezel and displays, are subject to change and

may not reﬂect the most current GTN software. Depictions of equipment

may differ slightly from the actual equipment.

NOTE: This device complies with part 15 of the FCC Rules. Operation is

subject to the following two conditions: (1) this device may not cause

harmful interference, and (2) this device must accept any interference

received, including interference that may cause undesired operation.

NOTE: This product, its packaging, and its components contain chemicals

known to the State of California to cause cancer, birth defects, or reproductive

harm. This notice is being provided in accordance with California’s Proposition

65. If you have any questions or would like additional information, please

refer to our web site at www.garmin.com/prop65.

NOTE: Canadian installations: In accordance with Canadian Radio

Speciﬁcations Standard 102 (RSS 102), RF ﬁeld strength exposure to

persons from an antenna connected to this device should be limited to 60

V/m for controlled environment and 28 V/m for uncontrolled environment.

NOTE: Do not use SafeTaxi or Chartview functions as the basis for

ground maneuvering. SafeTaxi and Chartview functions have not been

qualiﬁed to be used as an airport moving map display (AMMD). SafeTaxi

and Chartview are intended to improve pilot situational awareness

during ground operations should only be used by the ﬂight crew to

orient themselves on the airport surface.

NOTE: The FAA has asked Garmin to remind pilots who ﬂy with Garmin

database-dependent avionics of the following:

• It is the pilot’s responsibility to remain familiar with all FAA regulatory

and advisory guidance and information related to the use of databases in

the National Airspace System.

• Garmin equipment will only recognize and use databases that are

obtained from Garmin or Jeppesen. Databases obtained from Garmin

or Jeppesen are assured compliance with all data quality requirements

(DQRs) by virtue of a Type 2 Letter of Authorization (LOA) from the FAA. A

copy of the Type 2 LOA is available for each database and can be viewed

at http://ﬂy.garmin.com by selecting "Type 2 LOA Status."

• Use of a current Garmin or Jeppesen database in your Garmin equipment

is required for compliance with established FAA regulatory guidance, but

does not constitute authorization to ﬂy any and all terminal procedures

that may be presented by the system. It is the pilot’s responsibility to

operate in accordance with established AFM(S) and regulatory guidance

or limitations as applicable to the pilot, the aircraft, and installed

equipment.

NOTE: The pilot/operator must review and be familiar with Garmin’s

database exclusion list as discussed in SAIB CE-14-04 to determine what

data may be incomplete. The database exclusion list can be viewed at

www.ﬂygarmin.com by selecting "Database Exclusions List."

NOTE: The pilot/operator must have access to Garmin and Jeppesen

database alerts and consider their impact on the intended aircraft

operation. The database alerts can be viewed at www.ﬂygarmin.com by

selecting "Aviation Database Alerts."

NOTE: If the pilot/operator wants or needs to adjust the database, contact

Garmin Product Support.

NOTE: Garmin requests the ﬂight crew report any observed discrepancies

related to database information. These discrepancies could come in the

form of an incorrect procedure; incorrectly identiﬁed terrain, obstacles and

ﬁxes; or any other displayed item used for navigation or communication in

the air or on the ground. Go to FlyGarmin.com and select "Aviation Data

Error Report."

Welcome

Welcome to the GTN era of navigation. The Garmin GTN supports airway

navigation and ﬂexible ﬂight planning, including arrival and departure

procedures and precision approaches. All of these advanced features are easily

accessed with an easy-to-use touchscreen display, another ﬁrst for general

aviation. You can be conﬁdent in knowing that this product has been designed

to meet or exceed industry performance standards and is supported through a

global network of Garmin Aviation Distributors.

About This Guide

Take a little time to review the various sections of this guide to familiarize

yourself with it. First, read this section and the Getting Started section as an

introduction to quickly get you started with the GTN. The other sections are

not meant to necessarily be read in order, but provide detailed information

on the subject they contain as you need them. Do take the time to review the

information before using the product to assist you in getting the most out of

your avionics.

Generally, a feature will be described in a section that provides a brief

description, a graphic functional diagram, and step-by-step procedures. If read

cover-to-cover sequentially, the information may seem repetitive. The guide is

designed as a reference and learning tool where you will generally skip around

the document learning about a particular feature or function after becoming

familiar with the unit.

Electronic Document Features

Versions of this guide are saved in the Adobe Portable Document Format

(pdf) and have features that help the user navigate more easily through the

document. The cover icons, Table of Contents, Index, and side tabs (i.e., FPL,

Map, Trafﬁc, etc.) are hyperlinks that will take you directly to the selected item.

Versions of aviation products in the pdf format are available at www.garmin.

com/manuals.

1.1 Model Descriptions

This guide covers the operation of the GTN 725 and 750. In general, all

models will be referred to as the GTN 7XX, except where there are physical or

operational differences. The GTN units are 6.25 inches wide and 6 inches high.

The display is a 708 by 600 pixel, 6.9 inch diagonal color LCD with touchscreen

controls. The units include one removable SD data card for the databases and

software upgrades.

The GTN 7XX simpliﬁes your workload with an easy-to-use touch panel that

provides a visual display of both controls and functions. The required controls

are displayed for the selected function. Keys on the display allow you to access

and control their functions by a simple touch on the interactive display.

The GTN 7XX can integrate a variety of avionics that will not only simplify

operation, but also save panel space. The GTN 725 and 750 have their own

GPS/SBAS navigator and ﬂight planning functions. The GTN 750 adds VHF

Com and VHF Nav radios. Selected optional external equipment allows you

to display and control active trafﬁc systems, XM Entertainment Radio, XM

Weather, audio panel, and a Mode S transponder directly from the GTN 7XX

1.1.1 GTN 725

The GTN 725 has a GPS/SBAS engine and is TSO C146c certiﬁed for

primary domestic, oceanic, and remote navigation including en route, terminal,

and non-precision approaches, and approaches with vertical guidance, such

as LPV and LNAV/VNAV. The GTN 725 can simultaneously give aviators vital

approach information and weather and trafﬁc data in relation to their position

on a large, color moving map display. Thanks to a high-contrast color display,

the information can be easily read from wide viewing angles even in direct

sunlight. Its color moving map features a built-in database that shows cities,

highways, railroads, rivers, lakes, coastlines, and a complete Jeppesen database.

The Jeppesen database (that can be updated with a front-loading data card)

contains all airports, VORs, NDBs, Intersections, FSSs, Approaches, DPs/STARs,

and SUA information.

1.5.3 Dual GTN Installations

Dual GTN units when connected in the aircraft may be set up to communicate

and share information by “Crossﬁlling” or synchronizing information between

the two units.

The following Crossﬁll information is always synchronized between both

GTN units:

• User Waypoints

• Flight Plan Catalog

• Alerts (trafﬁc pop-up acknowledgement, missed approach waypoint pop-

up acknowledgement, altitude leg pop-up acknowledgement)

• External sensors (transponder status and commands, synchro heading)

• System setup:

– User-deﬁned NAV frequencies to store favorites

– Date/Time convention

– Nearest airport criteria

– Units (Nav angle, Fuel, and Temperature)

– User-deﬁned COM frequencies to store favorites

– CDI Scale setting

– ILS CDI Capture setting

This data is crossﬁlled only if crossﬁll is turned on by the pilot:

• Active navigation (ﬂight plan)

NOTE: In dual GTN installations with crossﬁll on, the OBS course will only

be updated in real time on the GTN that is receiving the new OBS course.

The course will be transferred to the other GTN when OBS is exited.

NOTE: There is an installer option to turn on a system message that will

be provided anytime crossﬁll is turned off to alert the pilot that ﬂight plans

are not being crossﬁlled.

1.10 Dead Reckoning

Dead reckoning is a feature that enables the GTN to provide limited navi-

gation using the last known position and speed after a loss of GPS navigation

while on an active ﬂight plan.

CAUTION: Navigation using dead reckoning is only an estimate and

should not be used as the sole means of navigation. Use other means of

navigation, if possible.

Dead reckoning becomes active after a loss of GPS position while navigating

using an active ﬂight plan and the ﬂight phase is either En Route (ENR) or

Oceanic (OCN).

“DR” will be overlayed on the ownship icon. The To/From ﬂag is removed

from the CDI. The Dead Reckoning annunciator (DR) appears on the lower

left side of the map display and will replace ENR or OCN when a GPS position

is unavailable and the unit is in Dead Reckoning mode. All external outputs

dependent on GPS position are ﬂagged.

Terrain will be noted as not available and new terrain advisory pop-ups will

not occur. Trafﬁc and StormScope information will not be shown on the Map

page, but will continue to be available on their own dedicated pages. XM weather

will still be available on the Map page.

Dead Reckoning mode will continue until GPS position is restored, when GPS

navigation is restored Dead Reckoning mode is exited. The DR annunciations

will be removed and GPS information will be used to compute navigation related

information for the current ﬂight phase.

Dead Reckoning is only allowed in En Route and Oceanic phases of ﬂight.

If the unit is in a Terminal or Approach phase of ﬂight when Dead Reckoning

takes place, “No GPS Position” will be displayed on the map pages and all

navigation data will be dashed. If you are operating in Dead Reckoning mode

and a transition to Terminal or Approach phases of ﬂight would occur from the

projected Dead Reckoning position, Dead Reckoning mode will be discontinued.

“No GPS Position” will be displayed on the map pages and all navigation data

will be dashed.

1.11 FastFind Predictive Waypoint Entry

FastFind provides the pilot with a shortcut to the nearest waypoint with an

identiﬁer that starts with the typed letters. As a result, the GTN can predict the

pilot's entry within as little as one key press.

FastFind predictions are shown in the top right-hand corner of the keypad

display. Touching the FastFind ﬁeld will select the predicted waypoint. If the

FastFind prediction is not what the pilot is looking for, keep typing until the

desired waypoint is displayed.

1.11.2 FastFind With A Flight Plan

When creating a new ﬂight plan or searching for a waypoint, the GTN

will search for waypoints closest to the current GPS position. When adding

waypoints in the middle of the ﬂight plan, the GTN will search halfway between

the previous and next waypoints. When adding waypoints at the end of the

ﬂight plan, the GTN will search for waypoints closest to the last waypoint in the

ﬂightplan.

1. When the aircraft is located in KSLE, and the last waypoint in

the ﬂight plan is "DRK", the GTN will search for waypoints

nearest "DRK".

2. Typing K, will result in "KPRC" being displayed as the FastFind

prediction because it is the nearest waypoint to "DRK" that

starts with "K".

2.1.10 GDL 88 ADS-B Reporting

The GDL 88 is a remote-mount ADS-B transceiver that sends ADS-B out

messages to ATC and other aircraft and communicates ADS-B In data to panel-

mounted avionics for the display of trafﬁc and weather. Reference the GDL

88 Pilot Guide for a full description of GDL 88 functions. When a GTN is

interfaced to a GDL88 transceiver for ADS-B Out functions the GTN can control

some aspects of the ADS-B Out message and the GTN may provide position

information to the GDL88. The display and control of the information sent

depends on the equipment installed and how it is conﬁgured. Some installations

allow control by the pilot of the information sent, while others do not.

The Anonymous Mode, when armed, will replace the identifying information

in the ADS-B Out message with a temporary randomized number for privacy

while the position information will still be provided. The call sign will be sent as

"VFR." To enable Anonymous Mode, the Squawk Code must be set to the VFR

code (based on the GDL 88 conﬁguration) and the Anonymous key must be

selected.

Viewing the ADS-B Control Panel Without Integrated Transponder Control

1. Touch the Transponder window to view the ADS-B control

panel.

2.2.4 3D Audio

Advanced processing adjusts audio in the headset to mimic how the human

ear normally hears and registers sounds in space. This 3-D Audio feature makes

it seem as though different audio sources are coming from different directions

around you. Now it’s much easier to focus on and understand one particular

source from among many. For example, COM 1 will seem to be coming from

the left while COM 2 will seem to be coming from the right. When 3D Audio is

disabled, balance is restored.

NOTE: The stereo/mono headsets must be in the stereo position in order

for 3D audio to function.

Touch the 3D Audio key to toggle the 3D Audio function on

and off.

This is currently done such that audio sources will either be 30 degrees

to your left (330 degrees), 30 degrees to your right, and directly in front (0

degrees). The following table details the left/right balance of the audio level

depending on the selected Com:

2.3.2 Co-Pilot is Passenger

When the GTN 7XX is installed with a GMA 35, the GTN can place the GMA

into "Co-Pilot is Passenger" mode. While in this mode, the GMA 35 treats the

copilot headset as a passenger headset and the co-pilot only hears what the other

passengers hear. This applies to intercom audio, alerts (if conﬁgured for the

passengers), selected audio (if conﬁgured for passengers), and music/telephone

distribution. "Co-Pilot is Passenger" mode allows simpler audio control for the

pilot when the co-pilot is just a passenger and not involved in ﬂying the aircraft.

1. To activate "Co-Pilot is Passenger" mode, open the Intercom

Setup page and touch Intercom.

2. Touch Menu, to display the Intercom Menu, and then touch

Group Co-Pilot with Passenger to enable "Co-Pilot is

Passenger" mode.

Figure 2-23 Set Co-Pilot as a Passenger in Intercom

NOTE: This feature should not be used for multi-crew aircraft. When the

co-pilot is treated as a passenger, co-pilot position may not hear audio

alerts or radios.

NOTE: While this mode is active, the co-pilot intercom and audio controls

are unavailable because the co-pilot intercom/audio is controlled by the

passenger controls. Split mode is also unavailable.

2.4 Telligence™ Voice Command

Garmin's Telligence Voice Command voice recognition feature allows

the pilot (and optionally copilot) to control the GTN 7XX connected

to a GMA 35 using spoken commands. To activate Voice Recognition,

push and hold the Push-to-Command (PTC) button while speaking a

command. When the Push-to-Command button is released, the GTN

7XX and/or the audio panel will respond.

If a command is understood by the GMA, a positive acknowledgement

chime will be played, and the relevant information will be displayed to

reﬂect the change (if applicable). The pilot should verify that the correct

response has occurred.

If a command is not understood by the GMA or the GTN is unable

to complete the requested action, a negative acknowledgement tone will

be played. The pilot should repeat the command by using the Push-to-

Command button, or by manually using the GTN 7XX touch screen. In

the event of any abnormal Voice Recognition operation, the front panel

controls and touch screen may be used to override Voice Recognition and

manually control the GTN 7XX.

NOTE 1: If Telligence Voice Command malfunctions and needs to be

disabled, remove power to the GMA 35 audio panel. This will force the

audio panel into the fail-safe mode. The pilot will be able to communicate

using the COM 2 radio only.

The following table lists the available Voice Recognition commands, the

associated actions, and the voice response if applicable:

3.3 Com Window and Tuning

Communication frequencies are selected by using the large and small right

knobs or by touching the value in the standby

Com

frequency ﬁeld and using

the displayed keypad. The standby frequency always appears below the active

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

and receive operations.

Once a frequency is selected in the standby ﬁeld, it may be transferred to the

active frequency by touching the active frequency ﬁeld.

NOTE: The Com window is normally active for adjustment, unless the NAV

window is made active by pressing the small right knob. The active state

automatically returns to the Com window after 30 seconds of inactivity.

To select a Com frequency using the small and large right knobs:

1. If the tuning cursor is not currently in the Com window,

press the small right knob momentarily. The Standby Com

frequency will be highlighted to indicate that it is active for

editing.

2. Turn the large right knob to select the desired megahertz

(MHz) value. For example, the “118” portion of the frequency

“118.30”.

3. Turn the small right knob to select the desired kilohertz

(kHz) value. For example, the “.30” portion of the frequency

“118.30”.

number is pressed that is not valid for the cursor location, the pilot is presented

with a conﬁrmation pop-up upon selecting the typed frequency. Frequency

entry can be accomplished by typing every digit in the frequency or by leaving

off the leading one and/or trailing zero(s). The frequency that will be entered is

always displayed in the cursor window.

3.3.4 Emergency Frequency

The GTN 750’s emergency frequency select provides a quick method

of selecting 121.50 MHz as the active frequency in the event of an in-ﬂight

emergency. The emergency frequency select is available whenever the unit is on,

regardless of GPS or cursor status, or loss of the display.

To quickly tune and activate 121.50, press and hold volume

knob or the remote Com ﬂip-ﬂop key for approximately

two seconds.

NOTE: Pressing and holding the remote Com FLIP/FLOP key for

approximately two seconds, on units so conﬁgured, will lock the COM

board, preventing further changes in Com frequency until the Com board is

unlocked, by pressing the remote Com FLIP/FLOP key again for two seconds.

The following message will notify the pilot that the Com board has been

locked: “COM LOCKED TO 121.5 MHZ. HOLD REMOTE COM TRANSFER

KEY TO EXIT.”

NOTE: Under some circumstances if the Com system loses communication

with the main system, the radio will automatically tune to 121.50 MHz for

transmit and receive regardless of the displayed frequency.

3.3.5 Stuck Microphone

Whenever the GTN 750 is transmitting, a “TX” indication appears in the

Com

window. If the push-to-talk key on the microphone is stuck or accidentally

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

the

Com

transmitter automatically times out (or ceases to transmit) after 30

seconds of continuous broadcasting. You will also receive a “

Com

push-to-talk

key stuck” message as long as the stuck condition exists.

3.3.6 Remote Frequency Selection Control

On units conﬁgured for remote Com frequency Recall, pressing the remote

recall switch will load the next preset Com frequency into the unit’s Standby

frequency box. The remote recall switch can be pressed multiple times to scroll

the entire preset frequency list through the Standby frequency box (the list will

“wrap” from the bottom of the list back up to the top, skipping any empty preset

positions).

The standby frequency isn’t activated until a Com FLIP/FLOP switch (either

bezel-mounted or remote (COM RMT XFR) is pressed. Remote Frequency Selection

only functions on units conﬁgured for a remote Com Frequency recall switch.

NOTE: For software prior to version 5.00, frequencies must be stored in

the User Frequency List prior to utilizing the remote channel select switch.

3.3.7 Reverse Frequency Look-Up

When the Reverse Frequency Look-Up feature is enabled in System-Setup,

the identiﬁer and frequency type will be shown for the selected Com and Nav

frequencies for the nearest stations that are in the aviation database when the

unit is receiving a valid position input. Station Identiﬁers with a “+” sign will

have more stations associated with this frequency than just the type displayed.

3.5.2 Nav Tuning Window

Nav frequencies are selected with the tuning cursor in the standby Nav

frequency ﬁeld, and using the small and large right knobs to dial in the desired

frequency. The keypad may also be used for frequency entry after touching

the Standby window. The standby frequency always appears below the active

frequency. The active frequency is the frequency currently in use. The GTN will

automatically decode Morse code and display the Ident for the active frequency

above it. The RFL (reverse frequency lookup) Identiﬁer is displayed below the

frequency and is only dependent on GPS position and database information.

NOTE: Tuning is normally active in the Com window, unless placed in the

Nav window by pressing the small right knob. When the tuning cursor is

in the Nav window, it automatically returns to the Com window after 30

seconds of inactivity. The active frequency in either window cannot be

accessed directly — only the standby frequency is active for editing.

To select a VOR/localizer/ILS frequency:

1. Touch the small right knob momentarily to make the Nav

Standby frequency value active for editing. The window will

be highlighted momentarily.

2. Turn the large right knob to select the desired megaHertz

(MHz) value. For example, the “117” portion of the frequency

“117.80”.

3. Turn the small right knob to select the desired kiloHertz

(kHz) value. For example, the “.80” portion of the frequency

“117.80”.

4. Touch the Nav active (top) frequency to make the standby

frequency.

5. The Active (top) and Standby frequencies will switch.

NOTE: The Chart feature provides a digital representation of a paper

chart and provides no vertical or lateral course guidance. Flight Plan and

Procedures are separate from Charts, and do provide vertical and lateral

course guidance for the loaded route or procedure shown on the Flight

Plan page. The term “Chart Unavailable” means that the chart cannot be

viewed on the Charts due to either a chart not being published, or an error

in the Chart database, but does not preclude its availability or inclusion of

the procedure in the Flight Plan or Procedures portion of the system. The

absence of a chart for a particular Departure, Arrival, or Approach does

not preclude its availability or inclusion in the Flight Plan or Procedures

portion of the system. The absence of a particular Departure, Arrival, or

Approach under the Flight Plan or Procedures portion of the system does

not preclude the ability to view the Chart for that procedure under the

Chart feature.

4.3.1 Store Flight Plan

A ﬂight plan must be saved to the Catalog to be used in future ﬂights. The

Store Flight Plan function will save the Active Flight Plan to the Catalog.

NOTE: If a ﬂight plan that includes a procedure that has been modiﬁed

by the pilot is saved into the ﬂight plan catalog, the GTN cannot check the

accuracy of that procedure when that ﬂight plan is used on a later ﬂight. It

is recommended that ﬂight plans with modiﬁed procedures not be saved

in the ﬂight plan catalog.

1. While viewing the Active Flight Plan page, touch the Menu

key. The Flight Plan Menu will be displayed.

2. Touch the Store key to store the current Active Flight Plan into

the Catalog. The ﬂight plan will be named by the beginning

and ending waypoints.

3. When a duplicate ﬂight plan is created, a warning dialog will

appear and the ﬂight plan will be saved with a numeral at the

end of the destination waypoint.

4.3.2 Invert Flight Plan

The Invert Flight Plan option allows you to reverse the Active ﬂight plan and

use it for navigation guidance back to your original departure point. The original

ﬂight plan stored in the catalog is not affected.

1. While viewing the Active Flight Plan page, touch the Menu

key. The Flight Plan Menu will be displayed.

2. Touch the Invert key to invert the current Active Flight Plan.

4.3.3 Parallel Track

Parallel Track allows you to create a parallel course offset of 1 to 99 NM to

the left or right of your current ﬂight plan. After setting a parallel track to your

current ﬂight plan, a magenta parallel track line will be drawn offset from the

original by the selected distance. The original course line will be drawn in grey.

The aircraft will navigate to the parallel track course line and external CDI/HSI

guidance will be driven from the parallel track.

When you reach the end of the ﬂight plan, a message will state, “Parallel

offset terminating in X seconds.” The message will be given when the aircraft

reaches the offset distance from the end of the parallel track. This will give the

pilot sufﬁcient time to intercept the original course.

Figure 4-38 Parallel Track Description

NOTE: Parallel track will be cancelled when graphically editing a ﬂight

plan.

4.4 Graphically Editing a Flight Plan

The Active Flight Plan may be edited graphically on the Map page. See

Section 9.3.3 for details.

4.5 Import Flight Plans with Connext

When the GTN is interfaced with a compatible Flight Stream device, ﬂight

plans can be wirelessly imported into the GTN from supported Apps (i.e.

Garmin Pilot). The imported ﬂight plans can then be activated or stored to the

ﬂight plan catalog once they are previewed by the pilot.

NOTE: Flight plans over 99 waypoints long are truncated at 99 waypoints

and the last waypoint in the imported/uploaded ﬂight plan may not be the

destination airport.

NOTE:

Flight plan information and user waypoints included as part of a

ﬂight plan will not necessarily retain their names when the ﬂight plan is

transferred from the portable device to the GTN via a Flight Stream device.

Whenever a User Waypoint is imported, it is compared to the existing User

Waypoint catalog. If it matches locations with an existing User Waypoint, the

waypoint will utilize the name saved in the GTN for that waypoint. If there is

not a location match, the waypoint is imported but without the name label

that the import software may have used. Therefore all new User Waypoints

will come in as USR### where the number is the lowest open User Waypoint

slot in the catalog.

If an imported ﬂight plan contains any errors, pop-up messages will be

displayed alerting the pilot of the issues and the resulting changes to the ﬂight

plan.

When the imported ﬂight plan is too long, the GTN will truncate the ﬂight

plan to the correct length. The pilot should be aware that waypoints are missing

from the end of the ﬂight plan, including the destination waypoint.

Figure 4-62 Pop-Up Message Reporting Flight Plan Errors

When the imported ﬂight plan contains waypoints (non-user waypoints),

procedures, or airways that are not found in navigation database, the GTN will

replace those waypoints with locked (lockd) waypoints. These locked waypoints

must be resolved prior to activating the ﬂight plan to provide navigation along

the ﬂight plan.

When more than one error occurs during the ﬂight plan import, the pilot

will need to cycle through the errors by touching the Next key on the pop-up.

4.6 Import Flight Plans with an SD Card

Flight plans can be created on a computer using compatible ﬂight planning

software and saved to the SD card to be imported into the GTN. The imported

ﬂight plans can then be activated or stored to the ﬂight plan catalog once they

are previewed by the pilot.

NOTE: Flight plans over 99 waypoints long are truncated at 99 waypoints

and the last waypoint in the imported/uploaded ﬂight plan may not be the

destination airport.

NOTE:

This feature is available in software version 5.10 and later.

NOTE:

The ﬂight plan ﬁle format used by the GTN is different than the ﬁle

2. If an imported flight plan contains any errors, pop-up

messages will be displayed alerting the pilot of the issues

and the resulting changes to the ﬂight plan. These pop-ups

are presented the ﬁrst time that the ﬂight plan is viewed on

the Flight Plan Preview page.

When the imported ﬂight plan is too long, the GTN will truncate

the ﬂight plan to the correct length. The pilot should be aware

that waypoints are missing from the end of the ﬂight plan.

Figure 4-72 Flight Plan Import Issue - Flight Plan Too Long

3. When the imported ﬂight plan contains waypoints (non-user

waypoints), procedures, or airways that are not found in

navigation database, the GTN will replace those waypoints

with locked waypoints. These locked waypoints must be

resolved prior to activating the ﬂight plan.

When more than one error occurs during the ﬂight plan import,

the pilot will need to cycle through the errors by touching the

Next key on the pop-up.

5 DIRECT-TO

The GTN 7XX Direct-To function can quickly set a course to any waypoint.

If the pilot selects Direct-To to a waypoint that is in the ﬂight plan, waypoint

sequencing in the ﬂight plan will resume upon reaching that waypoint. If the

pilot selects Direct-To for a waypoint that is not in the ﬂight plan, the ﬂight

plan will no longer be active but remains available. There are some ﬁxes within

procedures for which if a Direct-To is selected then the approach will not be

active. For example, if you activate a Direct-To course to a waypoint between

the FAF and the MAP and go Direct-To to that waypoint then approach guidance

will not become active.

5.1 Direct-To Navigation

1. Press the Direct-To key on the right side of the unit.

Figure 5-1 Direct-To Wpt Page

2. Select Waypoint, FPL, or NRST APT from the Direct-To

window by touching the desired tab.

3. If a speciﬁc course is desired, touch the Course To key.

6 PROCEDURES

The GTN 7XX 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

the card’s ﬁles have been updated. Approach procedures are not the same as the

approach plates available in ChartView, which is a separate database. Subscription

information for NavData cards is included in your GTN 7XX package.

The Procedures Page is displayed by touching the PROC key on the Home

page. The Procedures Page provides access to approaches, departures and

arrivals. Selections are also shown to: Activate Approach, Vectors to Final, and

Activate Missed Approach.
