WARNINGS,
CAUTIONS, & NOTES
WARNING: Navigation and terrain separation must NOT be predicated upon the use of the terrain function.
The G1000 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 altitude calculated by G1000 GPS receivers is geometric height above Mean Sea Level and could
vary significantly from the altitude displayed by pressure altimeters, such as the GDC 74A Air Data Computer,
or other altimeters in aircraft. GPS altitude should never be used for vertical navigation. Always use pressure
altitude displayed by the G1000 PFD or other pressure altimeters in aircraft.
WARNING: Do not use outdated database information. Databases used in the G1000 system must be updated
regularly in order to ensure that the information remains current. Pilots using any outdated database do so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 G1000 Multi Function Display 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: Use of the Stormscope is not intended for hazardous weather penetration (thunderstorm penetration).
Stormscope information, as displayed on the G1000 MFD, is to be used only for weather avoidance, not
penetration.
WARNING: GDL 69 Weather should not be used for hazardous weather penetration. Weather information
provided by the GDL 69 is approved only for weather avoidance, not penetration.
WARNING: NEXRAD weather data is to be used for long-range planning purposes only. Due to inherent delays
in data transmission and the relative age of the data, NEXRAD weather data should not be used for short-range
weather avoidance.

190-00384-08 Rev. A
WARNINGS,
CAUTIONS, & NOTES
WARNING: The Garmin G1000, as installed in Cessna Nav III aircraft, 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 G1000. 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: For safety reasons, G1000 operational procedures must be learned on the ground.
WARNING: 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 G1000 utilize GPS as a precision electronic
NAVigation AID (NAVAID). Therefore, as with all NAVAIDs, information presented by the G1000 can be misused
or misinterpreted and, therefore, become unsafe.
WARNING: To reduce the risk of unsafe operation, carefully review and understand all aspects of the G1000
Pilot’s Guide documentation. Thoroughly practice basic operation prior to actual use. During flight operations,
carefully compare indications from the G1000 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.
WARNING: The illustrations in this guide are only examples. Never use the G1000 to attempt to penetrate
a thunderstorm. Both the FAA Advisory Circular, Subject: Thunderstorms, and the Aeronautical Information
Manual (AIM) recommend avoiding “by at least 20 miles any thunderstorm identified as severe or giving an
intense radar echo.”
WARNING: Lamp(s) inside this product may contain mercury (HG) and must be recycled or disposed of according
to local, state, or federal laws. For more information, refer to our website at www.garmin.com/aboutGarmin/
environment/disposal.jsp.
WARNING: Because of anomalies in the earth’s magnetic field, operating the G1000 within the following areas
could result in loss of reliable attitude and heading indications. North of 70° North latitude and south of 70°
South latitude. An area north of 65° North latitude between longitude 75º West and 120º West. An area south
of 55° South latitude between longitude 120º East and 165º East.
CAUTION: The PFD and MFD 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.
Garmin G1000 Cockpit Reference Guide for the Cessna Nav III 190-00384-08 Rev. A
WARNINGS,
CAUTIONS, & NOTES
CAUTION: The Garmin G1000 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.
NOTE: When using Stormscope, there are several atmospheric phenomena in addition to nearby thunderstorms
that can cause isolated discharge points in the strike display mode. However, clusters of two or more discharge
points in the strike display mode do indicate thunderstorm activity if these points reappear after the screen has
been cleared.
NOTE: All visual depictions contained within this document, including screen images of the G1000 panel and
displays, are subject to change and may not reflect the most current G1000 system and aviation databases.
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: The GDU 1040 and GDU 1044B PFD/MFD may require a warm-up time of up to 30 minutes when exposed
to -40˚C for an extended period. A warm-up time of up to 15 minutes may be required when exposed to -30˚C
for an extended period.
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: Interference from GPS repeaters operating inside nearby hangars can cause an intermittent loss of
attitude and heading displays while the aircraft is on the ground. Moving the aircraft more than 100 yards
away from the source of the interference should alleviate the condition.
NOTE: Use of polarized eyewear may cause the flight displays to appear dim or blank.

SECTION 1: SYSTEM OVERVIEW
The purpose of this Cockpit Reference Guide is
to provide the pilot a resource with which to find
operating instructions on the major features of the
G1000 system more easily. It is not intended to be a
comprehensive operating guide. Complete operating
procedures for the complete system are found in the
Garmin G1000 Pilot’s Guide for the Cessna Nav III (190-
00498-03).
This guide gives the pilot abbreviated operating
instructions for the Primary Flight Display (PFD), Multi
Function Display (MFD), and the GMA 1347 Audio Panel
System.
NOTE: The pilot should read and thoroughly
understand the Cessna Pilot’s Operating
Handbook (POH) for limitations, procedures and
operational information not contained in this
Cockpit Reference Guide. The Cessna POH always
takes precedence over the information found in
this guide.

SECTION 1
SYSTEM OVERVIEW
1.5 VERTICAL NAVIGATION
One of two altitude sources is used by the G1000 when
giving vertical navigation guidance. WAAS GPS altitude
is used when giving guidance for a WAAS approach after
the Final Approach Fix. Baro corrected altitude is used
when vertical guidance is given in all other situations and
in non-WAAS systems.
The G1000 system can use altitude constraints
associated with lateral waypoints to give guidance for
vertical navigation. These altitudes are, depending on the
specific instance, entered by the pilot or retrieved from the
published altitudes in the navigation database.
The navigation database only contains altitudes
for procedures that call for “Cross at” altitudes. If the
procedure states “Expect to cross at,” then the altitude
is not in the database. In this case the altitude may be
entered manually.
NOTE: All arrival procedure altitudes contained in
the navigation database are for turbojet aircraft only.
Alter or enter altitudes as desired to comply with the
ATC clearance.
When activating or loading an arrival or approach
procedure into an active flight plan, the VNV ‘ALT’ fields
are populated with any altitudes that can be retrieved
from the navigation database.
Since altitudes loaded with an arrival procedure are
published only for turbojet aircraft, the altitudes are
displayed as white text indicating that the altitudes are
displayed for reference only. An arrival waypoint altitude
may be used (or “designated”) as is, or changed to a
different altitude. An altitude is designated by pressing the
FMS Knob and turning the large FMS Knob to place the
cursor on the desired altitude and pressing the ENT Key or
entering a different value and pressing the ENT Key. The
altitude is now displayed as light blue text, indicating that
the altitude is now designated to give vertical speed and
deviation guidance.
Approach waypoint altitude constraints are automatically
designated when the approach is loaded. These altitudes
are also displayed as light blue text. Waypoint altitude
constraints designated up to, but not including the FAF.
The FAF is always a “reference only” altitude and cannot be
designated, unless the selected approach does not provide
vertical guidance. In this case, the FAF altitude can be
designated manually.
Altitudes that have been designated for use in vertical
guidance may also be made “non-designated” by placing the
cursor over the desired altitude and pressing the CLR Key.
Other displayed altitudes may change due to re-calculations
or rendered invalid as a result of manually changing an
altitude to a non-designated altitude.
To help interpret the meanings of how the altitudes are
presented, keep the following points in mind:
• When the altitude is displayed in light blue,
the system is using that altitude (designated) to
determine vertical speed and deviation guidance.
• When the altitude is displayed in white, it is not being
used by the system (non-designated) to determine
the vertical speed and deviation guidance.
• An altitude displayed as small text is an altitude that
is published in the navigation database.
• Altitudes displayed as a light blue subdued text
cannot be used in the current vertical navigation
calculations.

Equipment section of the pilot’s guide.
1.8 DATABASE UPDATES
The G1000 System uses Secure Digital (SD) cards to
load and store various types of data. For basic flight op-
erations, SD cards are required for database storage as well
as Jeppesen aviation and ChartView database updates.
The following procedures pertain to updating the
G1000 system with SD cards as outlined in Appendix B of
the G1000 Cessna Nav III Pilot’s Guide.
Jeppesen Aviation Database
NOTE: After the aviation database is installed,
the card may be removed after loading the
update to each LRU.
Updating the Jeppesen aviation database:
1)
With the G1000 System OFF, insert the SD card
containing the aviation database update into the
top card slot of the PFD to be updated (Label of SD
card facing left).
2)
Turn the G1000 System ON. A prompt similar to
the following is displayed in the upper left corner
of the PFD:
Figure 1-11 Database Update Prompt

SYSTEM OVERVIEW
Figure 1-12 Database Update Confirmation
4)
After the update completes, the PFD starts in normal
mode.
5)
Turn the G1000 System OFF and remove the SD
card.
6)
Repeat steps 1 through 4 for the MFD. The MFD
and PFD databases are now updated. Remove the
SD card when finished.
7)
Verify that the correct update cycle is loaded during
startup of the MFD.
Garmin Databases
Since these databases are not stored internally in the
MFD or PFD, a Supplemental Data Card containing iden-
tical database versions must be kept in each display unit.
NOTE: The data contained in the terrain and
obstacle databases comes from government
agencies. Garmin accurately processes and
cross-validates the data, but cannot guarantee
the accuracy and completeness of the data.
1)
Insert one SD card in the bottom card slot of the
MFD and one in the bottom card slot of the PFD.
The SD card containing the ChartView or FliteCharts
database must be inserted into the bottom slot on
the MFD.
2)
Apply power to the G1000 System. View the MFD
power-up splash screen. Check that the databases
are initialized and displayed on the scrolling
window of the splash screen. When updating the
terrain and FliteCharts databases, an ‘in progress’
message may be seen. If this message is present,
wait for the system to finish loading before verifying
the correct databases are initialized, then proceed
to step 3.

NOTE: The LOW ALT annunciation is only available
in G1000 systems configured with WAAS-capable
GPS. Also, the LOW ALT annunciation is not
available when the G1000 is configured with
TAWS (Terrain Awareness & Warning System),
unless TAWS is inhibited.
When the Final Approach Fix (FAF) is the active
waypoint in a GPS WAAS approach using vertical guidance,
a LOW ALT (Low Altitude) annunciation may appear if
the current aircraft altitude is at least 164 feet below the
prescribed altitude at the FAF. The annunciation initially
flashes. After a few seconds the flashing stops and the
annunciation is displayed as shown in Figure 2-10.

information for performing engine leaning.
From the Lean Display, the pilot can utilize the CYL
SLCT and ASSIST softkeys to obtain information about
specific cylinders. Pressing the CYL SLCT (Cylinder
Select) Softkey cycles through the cylinders (i.e., changes
the cylinder indicated on the bar graphs in light blue).
This softkey is disabled when the ASSIST Softkey is
pressed or when a cylinder experiences a caution or
warning condition; the softkey remains disabled until the
temperature returns to normal.

The ASSIST Softkey aids in the leaning process by
identifying the peak of the first cylinder whose temperature
falls. If the temperature of the peaked cylinder exceeds
the peak value, the peak value is not updated. Press the
ASSIST Softkey to stop peak monitoring.
Normally-aspirated Aircraft
For normally-aspirated aircraft, when a cylinder peaks,
its peak is represented by a hollow block on the EGT Bar
Graph. The EGT readout for the peaked cylinder, indicat-
ed on the bar graph in light blue, appears directly beneath
the bar graph. The system automatically switches to the
first peak obtained and displays the temperature deviation
from peak (∆PEAK) in degrees Fahrenheit (°F) below the
EGT readout.
Turbocharged Aircraft
Leaning for turbocharged aircraft is done with refer-
ence to the Turbine Inlet Temperature (TIT). When the
temperature peaks, the numeric readout (∆PEAK) appears
below the TIT Indicator and displays the difference be-
tween peak and current TITs, in degrees Fahrenheit (°F).
If a peak is not displayed, underscores are shown until
one is established.
3.3 SYSTEM DISPLAY
NOTE: Fuel calculations do not use the aircraft
fuel quantity indicators and are calculated from
the last time the fuel was reset.
NOTE: The pilot should refer to the Pilot’s
Operating Handbook (POH) for fuel values and
limitations. The displayed fuel remaining can be
adjusted up to 53 gal (Models 172R, 172S) or 87
gal (Models 182T, T182T, 206H, T206H).
The System Display is accessed by pressing the
ENGINE Softkey followed by the SYSTEM Softkey and
shows critical engine, fuel, and electrical parameters.
Fuel calculations are based on the fuel flow totalizer
and the displayed fuel remaining, adjusted by the pilot
using the following softkeys:
• RST FUEL – Resets totalizer-based fuel remaining
(GAL REM) to zero and the fuel used (GAL USED)
to zero
• GAL REM – Gives access to softkeys for adjusting
the amount of fuel remaining for purposes of fuel
calculations
Fuel remaining can be adjusted in one or ten-gallon
increments using the appropriate softkeys. Softkeys also
allow entering the full tank quantity for the aircraft or the
tab quantity, which is 35 gallons (Models 172R and 172S)
or 64 gallons (Models 182T, T182T, 206H, and T206H).

CONTROL
NOTE: The Aircraft Flight Manual (AFM) always
supersedes the information in this guide. This
section only applies to the GFC 700 Automatic
Flight Control System (AFCS).
6.1 AFCS CONTROLS
The following dedicated AFCS keys are located on the
bezels of the PFD and MFD:
Figure 6-1 Dedicated AFCS Controls
The following AFCS controls are located in the cockpit
separately from the MFD:
• AP DISC Switch (Autopilot Disconnect)
Disengages the autopilot and interrupts pitch trim
operation. The red AP DISC Switch is located
forward of the MET Switch on the pilot’s control
wheel left grip. This switch may be used to
acknowledge an autopilot disconnect and mute the
associated aural tone.
•
CWS Button (Control Wheel Steering)
Momentarily disengages the autopilot and
synchronizes the flight director’s Command Bars
with the current aircraft pitch (if not in Glideslope
Mode) and roll (if in Roll Hold Mode).
The CWS
Button is located on the top of the pilot’s control
wheel right grip. Upon release of the CWS
Button, the flight director may establish new
reference points, depending on the current
pitch and roll modes.
• GA Switch (Go-Around)
Disengages the autopilot, selects flight director Go-
Around Mode, and activates the missed approach.
The GA Switch is located on the instrument
panel above the throttle.
•
MET Switch (Manual Electric Trim)
The MET Switch is located on the pilot’s control
wheel left grip. This composite switch is split
into left and right sides. The left switch is the
ARM contact and the right switch controls the DN
(forward) and UP (rearward) contacts. The MET
ARM switch can be used to disengage the autopilot
and to acknowledge an autopilot disconnect alert
and mute the associated aural tone. Manual trim
commands are generated only when both sides of
the switch are operated simultaneously. If either
side of the switch is active separately for more than
three seconds, MET function is disabled and ‘PTRM’
is displayed as the AFCS Status Annunciation on the
PFD. The function remains disabled until both sides
of the switch are inactivated.

6.2 FLIGHT DIRECTOR OPERATION
With the flight director activated, the aircraft can be
hand-flown to follow the path shown by the Command
Bars. Maximum commanded pitch (+20°/-15°) and bank
(22°) angles, vertical acceleration, and roll rate are limited
to values established during AFCS certification. The flight
director also provides commands to the autopilot.
Activating the Flight Director
Pressing the FD or AP Key (when the flight director is
not active) activates the flight director in default pitch/roll
modes. Pushing the GA Switch or any flight director mode
key activates the flight director in the respective mode(s).

AFCS Status Box
Flight director roll modes are shown on the left and
pitch on the right. Armed modes are annunciated in
white and active in green. Autopilot status is displayed in
the center of the AFCS Status Box.
6.3 FLIGHT DIRECTOR MODES
Flight director modes are normally selected
independently for the pitch and roll axes. Unless
otherwise specified, all mode keys are alternate action
(i.e., press on, press off). In the absence of specific mode
selection, the flight director reverts to the default pitch
and/or roll mode(s).
Armed modes are annunciated in white and active in
green in the AFCS Status Box. Under normal operation,
when the control for the active flight director mode is
pressed, the flight director reverts to the default mode(s)
for the axis(es). Automatic transition from armed to active
mode is indicated by the white armed mode annunciation
moving to the green active mode field and flashing for ten
seconds.
A flashing yellow mode annunciation and annunciator
light indicate loss of sensor (AHRS, ADC, IAU) or
navigation data (VOR, LOC, GPS, VNAV, WAAS) required
to compute commands. When such a loss occurs, the
system automatically begins to roll the wings level or
maintain the pitch angle, depending on the affected axis.
The flashing annunciation stops when the affected mode
key is pressed or another mode for the axis is selected.
If after ten seconds no action is taken, the flashing
annunciation stops and the flight director enters the
default mode for the affected axis.
Figure 6-4 Loss of VOR Signal
If the information required to compute a flight director
mode becomes invalid or unavailable, the flight director
automatically reverts to the default mode for that axis.
The flight director is automatically disabled if the attitude
information required to compute the default flight director
modes becomes invalid or unavailable.

Pitch Hold Mode (PIT)
When the flight director is activated (the FD Key is
pressed), Pitch Hold Mode is selected by default. Pitch
Hold Mode is indicated as the active pitch mode by the
green annunciation ‘PIT’. This mode may be used for
climb or descent to the Selected Altitude (shown above
the Altimeter), since Selected Altitude Capture Mode is
automatically armed when the mode is activated.
In Pitch Hold Mode, the flight director maintains a
constant pitch attitude, the pitch reference. The pitch
reference is set to the aircraft attitude at the moment
of mode selection. If the aircraft pitch attitude exceeds
the flight director pitch command limitations, the flight
director commands a pitch angle equal to the nose-up/
down limit.

Selected Altitude Capture Mode (ALTS)
Selected Altitude Capture Mode arms automatically
when the flight director is in Pitch Hold, Vertical Speed,
Flight Level Change, or Go Around Mode. This mode
is also armed automatically under Vertical Path Tracking
Mode when the Selected Altitude is to be captured
instead of the VNAV Target Altitude. The white ‘ALTS’
annunciation indicates Selected Altitude Capture Mode is
armed (see Figure 6-5 for example).
The ALT Knob is used to set the Selected Altitude,
shown above the Altimeter until Selected Altitude Capture
Mode becomes active.
As the aircraft nears the Selected Altitude, the flight
director automatically transitions to Selected Altitude
Capture Mode with Altitude Hold Mode armed (Figure
6-7). This automatic transition is indicated by the green
‘ALTS’ annunciation flashing for up to ten seconds and the
appearance of the white ‘ALT’ annunciation. The Selected
Altitude is shown as the Altitude Reference beside the
‘ALTS’ annunciation.
At 50 ft from the Selected Altitude, the flight director
automatically transitions from Selected Altitude Capture
to Altitude Hold Mode and holds the Selected Altitude
(shown as the Altitude Reference). As Altitude Hold Mode
becomes active, the white ‘ALT’ annunciation moves to the
active pitch mode field and flashes green for ten seconds
to indicate the automatic transition.

NOTE: Pressing the CWS Button while in Selected
Altitude Capture Mode does not cancel the
mode.
Use of the ALT Knob to change the Selected Altitude
while Selected Altitude Capture Mode is active causes the
flight director to revert to Pitch Hold Mode with Selected
Altitude Capture Mode armed for the new Selected
Altitude.
Altitude Hold Mode (ALT)
Altitude Hold Mode can be activated by pressing the
ALT Key; the flight director maintains the current aircraft
altitude (to the nearest ten feet) as the Altitude Reference.
The flight director’s Altitude Reference is shown in the
AFCS Status Box and is independent of the Selected
Altitude, displayed above the Altimeter. Altitude Hold
Mode active is indicated by a green ‘ALT’ annunciation in
the AFCS Status Box.
Altitude Hold Mode is automatically armed when
the flight director is in Selected Altitude Capture Mode.
Selected Altitude Capture Mode automatically transitions
to Altitude Hold Mode when the altitude error is less than
50 ft. In this case, the Selected Altitude becomes the flight
director’s Altitude Reference.
Changing the Altitude Reference
NOTE: Turning the ALT Knob while in Altitude
Hold Mode changes the Selected Altitude, but
not the flight director’s Altitude Reference and
does not cancel the mode.
With the CWS Button depressed, the aircraft can be
hand-flown to a new Altitude Reference. When the CWS
Button is released at the desired altitude, the new altitude
is established as the Altitude Reference.

Mode activation. Vertical Speed Mode does not consider
the relative position of the Selected Altitude in relation to
the current aircraft altitude at the time of mode activation,
so it is possible to use Vertical Speed Mode while not
climbing/descending to the Selected Altitude.
Vertical Speed Mode is activated by pressing the VS

Flight Level Change Mode (FLC)
NOTE: The Selected Altitude should be set before
selecting Flight Level Change Mode.
Flight Level Change Mode is selected by pressing the
FLC Key. When Flight Level Change Mode is active, the
flight director continuously monitors Selected Altitude,
airspeed, and altitude. This mode acquires and maintains
the Airspeed Reference while climbing or descending to
the Selected Altitude (shown above the Altimeter). The
Airspeed Reference is set to the current airspeed upon
mode activation. Flight Level Change Mode is indicated
by an ‘FLC’ annunciation beside the Airspeed Reference
in the AFCS Status Box. The Airspeed Reference is also
displayed directly above the Airspeed Indicator, along
with a bug corresponding to the Airspeed Reference along
the tape.
Engine power must be adjusted to allow the autopilot
to fly the aircraft at a pitch attitude corresponding to the
Airspeed Reference and the desired flight profile (climb or

Vertical Navigation Modes (VPTH, ALTV)
NOTE: Pressing the CWS Button while Vertical
Path Tracking Mode is active does not cancel
the mode. The autopilot guides the aircraft back
to the descent path upon release of the CWS
Button.
NOTE: VNAV flight director pitch modes are
available only in conjunction with GPS roll
modes.
NOTE: The Selected Altitude takes precedence
over any other vertical constraints.
Vertical Navigation (VNAV) flight control is available
for enroute/terminal cruise and descent operations when
VNAV has been enabled and a VNAV flight plan (with at
least one vertical waypoint) or direct-to with a vertical
constraint has been activated. Refer to the Navigation
section for more information on VNAV flight plans. The
flight director may be armed for VNAV at any time, but no
target altitudes are captured during a climb.
The Command Bars provide vertical profile guidance
based on specified altitudes (entered manually or loaded
from the database) at waypoints in the active flight plan
or vertical direct-to. The appropriate VNAV flight control
modes are sequenced by the flight director to follow the
path defined by the vertical profile. Upon reaching the
last waypoint in the VNAV flight plan, the flight director
transitions to Altitude Hold Mode and cancels any armed
VNAV modes.
Vertical Path Tracking Mode (VPTH)
NOTE: If another pitch mode key is pressed while
Vertical Path Tracking Mode is selected, Vertical
Path Tracking Mode reverts to armed.
When a vertical profile (VNAV flight plan) is active and
the VNV Key is pressed, Vertical Path Tracking Mode is
armed in preparation for descent path capture. ‘VPTH’ (or
‘/V’ when Glidepath or Glideslope Mode is concurrently
armed) is annunciated in white in addition to previously
armed modes. If applicable, the appropriate altitude
capture mode is armed for capture of the next VNAV
Target Altitude (ALTV) or the Selected Altitude (ALTS),
whichever is greater.
Figure 6-10 Vertical Path Tracking Armed Annunciations
Prior to descent path interception, the Selected Altitude
must be set below the current aircraft altitude by at least
75 ft. For the flight director to transition from Altitude
Hold to Vertical Path Tracking Mode, acknowledgment is
required within five minutes of descent path capture by:
• Pressing the VNV Key
• Adjusting the Selected Altitude
If acknowledgment is not received within one minute of
descent path interception, the white ‘VPTH’ annunciation
and the VNV Key annunciator light start to flash. Flashing
continues until acknowledged or the descent path is
intercepted. If the descent is not confirmed by the time of
interception, Vertical Path Tracking Mode remains armed
and the descent is not captured.

Automatic Pitch Hold Reversion
Several situations can occur while Vertical Path
Tracking Mode is active which cause the flight director to
revert to Pitch Hold Mode. Vertical Path Tracking and the
appropriate altitude capture modes are armed for possible
descent profile recapture if the vertical deviation:
• Exceeds 200 ft during an overspeed condition
• Experiences a discontinuity exceeding 200 ft due to
a flight plan change
• Becomes invalid due to excessive cross-track error,
track angle error
• Cannot be computed for a leg type (such as a hold
or procedure turn)
The following circumstances cause mode reversion
without arming Vertical Path Tracking Mode:
• Navigation source manually changed from GPS
• CNCL VNV Softkey selected on the Active Flight
Plan Page (MFD)
• All remaining vertical waypoints deleted from the
flight plan
• Displays entering Reversionary Mode
Non-Path Descents
Pitch Hold, Vertical Speed, and Flight Level Change
modes can also be used to fly non-path descents while

VNAV flight control is selected. If the VS or FLC Key
is pressed while Vertical Path Tracking Mode is selected,
Vertical Path Tracking Mode reverts to armed along with
the appropriate altitude capture mode to allow profile re-
capture.
Figure 6-13 Flight Level Change VNAV Non-Path Descent
To prevent immediate profile re-capture, the following
must be satisfied:
• At least ten seconds have passed since the non-path
transition was initiated
• Vertical deviation from the profile has exceeded 250
ft, but is now less than 200 ft
Pressing the VNV Key twice re-arms Vertical Path
Tracking for immediate profile re-capture.
VNAV Target Altitude Capture Mode (ALTV)
NOTE: Armed VNAV Target Altitude and Selected
Altitude capture modes are mutually exclusive.
However, Selected Altitude Capture Mode is
armed implicitly (not annunciated) whenever
VNAV Target Altitude Capture Mode is armed.
This ensures the Selected Altitude is not violated
during a change from VNAV Target Altitude
Capture to Selected Altitude Capture Mode close
to Selected Altitude interception.
VNAV Target Altitude Capture is analogous to Selected
Altitude Capture Mode and is armed automatically
after the VNV Key is pressed and the next VNAV Target
Altitude is to be intercepted before the Selected Altitude.
The annunciation ‘ALTV’ indicates that the VNAV Target
Altitude is to be captured. VNAV Target Altitudes are
shown in the active flight plan or vertical direct-to, and
can be entered manually or loaded from a database (see
the Navigation section for details). At the same time as
“TOD within 1 minute” is annunciated in the Navigation
Data Box, the VNAV Target Altitude is displayed above the
Vertical Speed Indicator (see Figure 6-12). VNAV Target
Altitudes can be modified until VNAV Target Altitude
Capture Mode becomes active.
As the aircraft nears the VNAV Target Altitude, the
flight director automatically transitions to VNAV Target
Altitude Capture Mode with Altitude Hold Mode armed.
This automatic transition is indicated by the green ‘ALTV’
annunciation flashing for up to ten seconds and the
appearance of the white ‘ALT” annunciation. The VNAV
Target Altitude is shown as the Altitude Reference beside
the ‘ALTV’ annunciation.
At 50 ft from the VNAV Target Altitude, the flight
director automatically transitions from VNAV Target
Altitude Capture to Altitude Hold Mode and tracks the
level leg. As Altitude Hold Mode becomes active, the
white ‘ALT’ annunciation moves to the active pitch mode
field and flashes green for ten seconds to indicate the
automatic transition. The flight director automatically
arms Vertical Path Tracking, allowing upcoming descent
legs to be captured and subsequently tracked.

When the CDI has automatically switched from GPS to
LOC during a LOC/ILS approach, GPS Navigation Mode
remains active, providing GPS steering guidance until
the localizer signal is captured. LOC Navigation Mode is
armed in anticipation of localizer signal capture if the APR
Key is not pressed prior to the automatic source switch.
If Navigation Mode is active and either of the following
occur, the flight director reverts to Roll Hold Mode (wings
rolled level):
• Different VOR is tuned while in VOR Navigation
Mode (VOR Navigation Mode reverts to armed)
• Navigation source is manually switched
• Localizer signal is not captured by the final approach
fix (FAF) while in LOC Navigation Mode
Changing the Selected Course
The Selected Course on the PFD is controlled using the
CRS Knob. Pressing the CWS Button and hand-flying
the aircraft does not change the Selected Course while in
Navigation Mode. The autopilot guides the aircraft back
to the Selected Course (or GPS flight plan) when the CWS
Button is released.
Approach Mode (GPS, VAPP, LOC)
NOTE: The selected navigation receiver must have
a valid VOR or LOC signal or active GPS course
for the flight director to enter Approach Mode.
Approach Mode is activated when the APR Key is
pressed. Approach Mode acquires and tracks the selected
navigation receiver on the HSI (GPS, VOR, or LOC),
depending on the loaded approach. This mode uses the
selected navigation receiver deviation and desired course
inputs to fly the approach. Approach Mode provides
greater sensitivity for signal tracking than Navigation
Mode.
Pressing the APR Key when the CDI is greater than
one dot arms the selected approach mode (annunciated
in white to the left of the active roll mode). If the selected
navigation receiver is GPS, pressing the APR Key arms
GPS Approach Mode, provided that a GPS approach has
been loaded into the flight plan. If the loaded approach
provides WAAS-based vertical guidance, Glidepath Mode
is also armed (Figure 6-16). If GPS Approach Mode is
selected while in GPS Navigation Mode, capture can occur
with crosstrack error of up to 2 nm.

6.4 AUTOPILOT OPERATION
NOTE: Refer to the AFM for specific instructions
regarding emergency procedures.
Cessna Nav III’s autopilot operates flight control
surface servos to provide automatic flight control. The
autopilot controls the aircraft pitch and roll attitudes
following commands received from the flight director.
Pitch autotrim provides trim commands to the pitch trim
adapter to relieve any sustained effort required by the
pitch servo.
Flight Control
Pitch and roll commands are provided to the servos,
based on the active flight director modes. Servo motor
control limits the maximum servo speed and torque. The
servo gearboxes are equipped with slip-clutches set to
certain values. This allows the servos to be overridden in
case of an emergency.
Pitch Axis and Pitch Trim
The autopilot pitch axis uses pitch rate to stabilize the
aircraft pitch attitude during upsets and flight director
maneuvers. Flight director pitch commands are rate- and
attitude-limited, combined with pitch damper control, and
sent to the pitch servo motor. The pitch servo measures
the output effort (torque) and provides this signal to the
pitch trim servo. The pitch trim servo commands the
motor to reduce the average pitch servo effort.
When the autopilot is not engaged, the pitch trim servo
may be used to provide manual electric trim. This allows
the aircraft to be trimmed using a control stick switch
rather than the trim wheel. Manual trim commands are
generated with the MET Switch. Trim speeds are scheduled
with airspeed to provide more consistent response.
Roll Axis
The autopilot roll axis uses roll rate to stabilize aircraft
roll attitude during upsets and flight director maneuvers.
The flight director roll commands are rate- and attitude-
limited, combined with roll damper control, and sent to
the roll servo motor.
Engaging the Autopilot
NOTE: Autopilot engagement/disengagement is
not equivalent to servo engagement/disengage-
ment. Use the CWS Button to disengage the
pitch and roll servos while the autopilot remains
active.
When the AP Key is pressed, the autopilot and flight
director (if not already engaged) are activated. Engagement
is indicated by a green ‘AP’ annunciation in the center of
the AFCS Status Box. The flight director engages in Pitch
and Roll Hold modes when initially activated.

Control Wheel Steering
During autopilot operation, the aircraft may be hand-
flown without disengaging the autopilot. Pressing and
holding the CWS Button disengages the pitch and roll
servos from the flight control surfaces and allows the
aircraft to be hand-flown. At the same time, the flight
director is synchronized to the aircraft attitude during the
maneuver. The ‘AP’ annunciation is temporarily replaced
by ‘CWS’ in white for the duration of CWS maneuvers.
In most scenarios, releasing the CWS Button reengages
the autopilot with a new reference. Refer to the flight
director modes section for CWS behavior in each mode.

Disengaging the Autopilot
Automatic disengagement occurs due to:
• System failure
• Inability to compute default flight director modes
(FD also disengages automatically)
• Invalid sensor data
Automatic autopilot disengagement is indicated by
a flashing red ‘AP’ annunciation and by the autopilot
disconnect aural alert, which continue until acknowledged
by pushing the AP DISC or MET Switch.

ual disengagement, the autopilot disconnect aural alert
may be cancelled by pushing the MET ARM or AP DISC
Switch (AP DISC Switch also cancels the flashing ‘AP’ an-
nunciation).

6.5 EXAMPLE PROCEDURES
NOTE: The diagrams in this section are for instruc-
tional purposes only and should not be used for
navigation.
This section provides a scenario-based set of procedures
showing various GFC 700 AFCS modes used while
following a previously entered flight plan. The following
example closely follows the example flight plan discussed
in the Navigation section. Refer to the example in Section
7 - Navigation when studying the this example.
In this scenario, the aircraft departs Charles B. Wheeler
Downtown Airport (KMKC), enroute to Colorado Springs
Airport (KCOS). After departure, the aircraft climbs to
12,000 ft and airway V4 is intercepted after following
heading vectors of 240˚ and 290˚ assigned by ATC . Airway
V4 is flown to Salina VOR (SLN) using VOR navigation,
then airway V244 is flown using a GPS flight plan. The
ILS approach for runway 35L and LPV (WAAS) approach
for runway 35R are shown and a missed approach is
executed.

Intercepting a VOR Radial
During climb-out, the autopilot continues to fly the
aircraft in Heading Select Mode. Airway V4 to Salina
VOR (SLN) should now be intercepted. Since the
enroute flight plan waypoints correspond to VORs, flight
director Navigation Mode using either VOR or GPS as the
navigation source may be used. In this scenario, VOR
Navigation Mode is used for navigation to the first VOR
waypoint in the flight plan.
Intercepting a VOR radial:
1)
Arm VOR Navigation Mode:
a) Tune the VOR frequency.
b) Press the CDI Softkey to set the navigation
source to VOR.
c) Use the CRS Knob to set the Selected Course to
255°. Note that at this point, the flight director
is still in Heading Select Mode and the autopilot

Descent
While flying the arrival procedure, the aircraft is
cleared for descent in preparation for the approach to
KCOS. Three methods are presented for the descent from
12,000 ft:
• Flight Level Change descent – Flight Level Change
Mode can be used to descend to the Selected Alti-
tude at a constant airspeed. This descent method
does not account for flight plan waypoint altitude
constraints.
• Vertical Path Tracking descent – Vertical Path Track-
ing Mode is used to follow the vertical descent path
defined in the GPS flight plan. Altitude constraints
correspond to waypoints in the flight plan. Before
VNV flight control can provide vertical profile
guidance, a VNV flight plan must be entered and
enabled.
• Non-path descent in a VNV scenario – While
the flight director is following VNV guidance for
descent, Pitch Hold, Vertical Speed, or Flight Level
Change Mode can be used to descend to the VNV
Target Altitude prior to reaching the planned TOD.
Flight Level Change Mode is used in the example.
Flight Level Change descent:
1)
Select Flight Level Change Mode:
a) Using the ALT Knob, set the Selected Altitude to
10,000 feet.

7.3 NAVIGATING AN EXAMPLE FLIGHT
PLAN
NOTE: The following example flight plan is
for instructional purposes only. All database
information depicted should be considered not
current.
The following discussion is an example of navigating a
flight plan with the WAAS capable GPS system while the
G1000 provides vertical guidance through descents. A
lateral flight plan (LNAV) would be navigated in much the
same way, but would not include vertical guidance when
the final approach course is active.
The example is a flight plan from KMKC to KCOS filed
using the TIFTO2 departure, various Victor Airways, and
the DBRY1 arrival with the transition at TBE. Enroute
altitude will be 12,000 feet. An LPV (WAAS) approach
will be selected for runway 35R. A missed approach will
be executed at the Missed Approach Point (MAP). A few
enroute changes are demonstrated.
NOTE: If the loaded arrival procedure has
published altitudes contained in the navigation
database, these are for turbojet aircraft only.
Accept or change these values as desired to meet
the requirements of the clearance.
1)
Prior to departure, the TIFTO2 departure, the
airways, and the DBRY1 arrival at KCOS are loaded.
See the Procedures section for loading departures
and arrivals. Note the magenta arrow in Figure
7-11 indicating the active departure leg.
After takeoff, ATC assigns a heading of 240º.

press the ENT Key. Note in Figure 7-21, the
magenta arrow in the flight plan window and
magenta line on the map indicating V4 is now the
active flight plan leg. Note also, the crosstrack
(XTK) distance on the HSI indicating 16.9 nm
to the intercept point. Note the phase of flight
remained in Terminal (TERM) mode up to this
point because a departure leg was active. Since
a leg after the departure is now active, the current
CDI flight phase is ENR (Enroute) and CDI scaling
has changed to 2.0 nm.

g) Enter the offset, or distance from the waypoint
at which the selected altitude will be reached. In
this case, three miles prior to OPSHN is entered.
In other words, the G1000 gives vertical guidance
so the aircraft will arrive at an altitude of 10,000
feet three miles prior to OPSHN.
h) Press the ENT Key twice to activate the direct-to.
Note, in Figure 7-29, the magenta arrow in the
Active Flight Plan Window indicating the direct-to
OPSHN after the offset waypoint for OPSHN. The
preceding offset waypoint indicates the offset
distance and altitude that was previously entered.
The remaining waypoints in the loaded arrival
procedure have no database specified altitudes,
therefore, dashes are displayed. Keep the CDI
centered and maintain a track along the magenta
line to OPSHN.
Note the Direct-to waypoint is within the loaded
arrival procedure, therefore, phase of flight scaling
for the CDI changes to Terminal Mode and is
annunciated by displaying ‘TERM’ on the HSI.
NOTE: If the loaded arrival procedure has
waypoints with altitude constraints retrieved
from the database, those altitudes are displayed
as white numerals. This indicates the altitudes will
not be used by the system for vertical guidance
until manually accepted by the pilot. To accept
the displayed altitude, place the cursor over the
altitude and press the ENT Key. The altitude entry
then changes to light blue numerals, indicating
the altitude will now be used by the system for
providing vertical guidance.

Note the altitude constraints associated with each
of the approach waypoints as seen in Figure 7-33.
These altitudes are loaded from the database and
are displayed as light blue text, indicating these
values are “designated” for use in computing
vertical deviation guidance.
If it is desirable not to use the displayed altitude
for calculating vertical deviation guidance, perform
the following:
a) Press the FMS Knob to activate the cursor.
b) Turn the small FMS Knob to highlight the desired
altitude.

d) Press the FMS Knob to deactivate the cursor.
After making the altitude “non-designated”, it is
displayed as white text.
Altitude constraint values associated with the
Final Approach Fix (FAF) and waypoints beyond
the FAF cannot be designated for vertical
guidance. These altitude values are always
displayed as white text, as in Figure 7-34. Vertical
guidance from the FAF to the Missed Approach
Point (MAP) is given using the WAAS GPS altitude
source, therefore, the displayed altitude values
are for reference only.
Figure 7-34 Vertical Guidance is Active to the FAF
14)
As the aircraft approaches OPSHN, it may be
desirable to adjust how fast, or steep, the upcoming
descent will be. The default Flight Path Angle (FPA)
is -2.5 degrees and a required vertical speed is
computed to maintain the -2.5 FPA. To change the
vertical flight path, perform the following steps.

The flight continues through the arrival procedure
to PYNON (see Figure 7-42). At a point 31 nautical
miles from the destination airport, the phase of
flight scaling for the CDI changes to Terminal Mode
and is annunciated by displaying ‘TERM’ on the
HSI.
There will be a descent to HABUK in the next leg.
Note the TOD point on the map. Annunciations
for the upcoming turn and descent, as well as
the VDI and RVSI, appear on the PFD as the flight
progresses.

Upon passing PYNON the approach procedure
automatically becomes active. The approach may
be activated at any point to proceed directly to the
IAF. In this example, the aircraft has progressed
through the final waypoint of the arrival and the
flight plan has automatically sequenced to the IAF
as the active leg, activating the approach procedure
(see Figure 7-43).

After crossing FALUR the next waypoint is the
FAF. The flight phase changes to LPV on the HSI
indicating the current phase of flight is in Approach
Mode and the approach type is LPV. CDI scaling
changes accordingly and is used much like a localizer
when flying an ILS approach. The RVSI is no longer
displayed and the VDI changes to the Glidepath
Indicator (as shown in Figure 7-46) when the final
approach course becomes active.
Figure 7-46 Descending to the FAF
The descent continues through the FAF (CEGIX)
using the Glidepath Indicator, as one would use
a glideslope indicator, to obtain an altitude “AT”
7,800 feet at the FAF. Note the altitude restriction
lines over and under (‘At’) the altitude in the ‘ALT’
field in Figure 7-46.
24)
After crossing CEGIX, the aircraft continues
following the glidepath to maintain the descent to
“AT or ABOVE” 6,370 feet at the Missed Approach
Point (MAP) (RW35R) as seen in Figure 7-47.
Figure 7-47 Descending to the Missed Approach Point

SECTION 7 – NAVIGATION
7-20
In this missed approach procedure, the fix
immediately following the MAP (in this case
‘6368FT’) is not part of the published procedure.
It is simply a fix that defines a leg which guides
the aircraft along the runway centerline until
the required altitude to make the first turn on
the missed approach is exceeded. In this case,
if the aircraft altitude is below the specified
altitude (6,368 feet) after crossing the MAP, a
direct-to is established to this fix until an altitude
of 6,368 feet reached. After reaching 6,368
feet, a direct-to is established to the published
fix (in this case MOGAL). If the aircraft altitude
is above the specified altitude after crossing the
MAP, a direct-to is established to the published
fix (MOGAL) to begin the missed approach
procedure. The altitude constraint value defaults
to 400 feet AGL when the fix is not part of the
published procedure.
In some missed approach procedures this altitude
fix may be part of the published procedure. For
example, the procedure dictates a climb to 5,500
feet, then turn left and proceed to the Missed
Approach Hold Point (MAHP). In this case, the
altitude fix would be labeled ‘5500FT’. Again, if
the aircraft altitude is lower than this prescribed
altitude, a direct-to is established to this fix when
the missed approach procedure is activated.
25)
Upon reaching the MAP, it is decided to execute a
missed approach. Automatic waypoint sequencing is
suspended past the MAP. Press the
SUSP
Softkey on
the PFD to resume automatic waypoint sequencing
through the missed approach procedure.
A direct-to is initiated to MOGAL, which is the
Missed Approach Hold Point (MAHP) as seen in
Figure 7-48. The aircraft is climbing to 10,000
feet. The CDI flight phase now changes from LPV
to MAPR as seen on the HSI.

9.2 APPROACHES
NOTE: If certain GPS parameters (WAAS, RAIM,
etc.) are not available, some published approach
procedures for the desired airport may not be
displayed in the list of available approaches.
Not all approaches in the database are approved for GPS
use. When selecting an approach, a “GPS” designation to
the right of the procedure name indicates the procedure
can be flown using the GPS receiver. Some procedures do
not have this designation, meaning the GPS receiver can
be used for supplemental navigation guidance only. If the
GPS receiver cannot be used for primary guidance, the ap-
propriate navigation receiver must be used for the selected
approach (e.g., VOR or ILS). The final course segment of
ILS approaches, for example, must be flown by tuning the
Nav receiver to the proper frequency and selecting that
Nav receiver on the CDI.
The G1000 GPS allows for flying LNAV, LNAV/VNAV
(WAAS only), and LPV (WAAS only) approaches accord-
ing to the published chart. The active appoach type is
annunciated on the HSI as shown in the following table:

• NEXRAD base reflectivity does not provide
sufficient information to determine cloud layers or
precipitation characteristics (hail vs. rain, etc).
• An individual NEXRAD site cannot depict high
altitude storms at close ranges, and has no
information about storms directly over the site.
• The resolution of displayed NEXRAD data is 4 square

Forward Looking Terrain Avoidance (FLTA)
The Forward Looking Terrain Avoidance alert is
composed of two sub-functions:
Reduced Required Terrain Clearance (RTC) and
Reduced Required Obstacle Clearance (ROC)
This provides alerts when the aircraft flight path
is above terrain and/or obstacles, yet is projected to
come within minimum clearance values outlined in the
following table. When an RTC or ROC alert is issued, a
potential impact point is displayed on the TAWS Page as
a yellow or red ‘X’.
Imminent Terrain Impact (ITI) and Imminent
Obstacle Impact (IOI)
This provides alerts when the aircraft is below the
elevation of terrain in the aircraft’s projected path. ITI and
IOI alerts are accompanied by a potential impact point
displayed on the TAWS Page as a yellow or red ‘X’. The
alert is given when the projected vertical flight path is
calculated to come within minimum clearance altitudes
in the following table.
Phase of Flight Level Flight Descending
Enroute 700 ft. 500 ft.
Terminal 350 ft. 300 ft.
Approach 150 ft. 100 ft.
Departure 100 ft. 100 ft.
During the final approach phase of flight, RTC/ROC/
ITI/IOI alerts are automatically inhibited when the aircraft
is below 200 feet AGL while within 0.5 nm of the approach
runway or is below 125 feet AGL while within 1 nm of the
runway.
Premature Descent Alert (PDA)
A Premature Descent Alert is issued when the system
detects that the aircraft is significantly below the normal
approach path to a runway. The PDA alert mode functions
only during descent to land.
PDA alerting begins when the aircraft is within 15 nm
of the destination airport and ends when the aircraft is
either 0.5 nm from the runway threshold OR is at an alti-
tude of 125 feet AGL while within 1 nm of the threshold.
During the final descent, algorithms set a threshold for
alerting based on speed, distance, and other parameters.

11.6 DEAD RECKONING
WARNING: DR Mode is inherently less accurate
than the standard GPS/WAAS Mode due to the
lack of satellite measurements needed to deter-
mine a position. Changes in wind speed and/or
wind direction compound the relative inaccuracy
of DR Mode. Because of this degraded accuracy,
the crew must maintain position awareness using
other navigation equipment until GPS-derived
position data is restored.
While in Enroute or Oceanic phase of flight, if the
G1000 detects an invalid GPS solution or is unable to
calculate a GPS position, the system automatically reverts
to Dead Reckoning (DR) Mode. In DR Mode, the G1000
uses its last-known position combined with continuously
updated airspeed and heading data (when available) to
calculate and display the aircraft’s current estimated
position.
NOTE: Dead Reckoning Mode only functions in
Enroute (ENR) or Oceanic (OCN) phase of flight.
In all other phases, an invalid GPS solution
produces a ‘NO GPS POSITION’ annunciation on
the map and the G1000 stops navigating in GPS
Mode.
DR Mode is indicated on the G1000 by the appearance
of the letters ‘DR’ superimposed in yellow over the ‘own
aircraft’ symbol as shown in Figure 11-4. In addition,
‘DR’ is prominently displayed, also in yellow, on the HSI
slightly above and to the right of the aircraft symbol on the
CDI as shown in Figure 11-4. Also, the CDI deviation bar
is removed from the display. Lastly, but at the same time,
a ‘GPS NAV LOST’ alert message appears on the PFD.
Normal navigation using GPS/WAAS source data
resumes automatically once a valid GPS solution is
restored.
It is important to note that estimated navigation
data supplied by the G1000 in DR Mode may become
increasingly unreliable and must not be used as a sole
means of navigation. If while in DR Mode airspeed and/or
heading data is also lost or not available, the DR function
may not be capable of accurately tracking your estimated
position and, consequently, the system may display a path
that is different than the actual movement of the aircraft.
Estimated position information displayed by the G1000
through DR while there is no heading and/or airspeed
data available should not be used for navigation.
Figure 11-4 Dead Reckoning Indications
Symbolic Aircraft
(Map pages and Inset Map)
CDI ‘DR’ Indication on PFD
As a result of operating in DR Mode, all GPS-derived
data is computed based upon an estimated position and is
displayed as yellow text on the display to denote degraded
navigation source information. This data includes the
following:
• Navigation Status Box fields except Active Leg, TAS,
and DTK
• GPS Bearing Pointer
• Wind data and pointers in the Wind Data Box on
the PFD and MFD
• Track Bug
• All Bearing Pointer Distances
• Active Flight Plan distances, bearings, and ETE
values

SECTION 12: ANNUNCIATIONS &
ALERTS
NOTE: The Cessna aircraft Pilot’s Operating
Handbook (POH) supersedes information found
in this document.
The G1000 Alerting System conveys alerts to the pilot
using a combination of the following items:
• Annunciation Window: The Annunciation Window
displays abbreviated annunciation text. Text color is
based on alert levels described later in the Alert Levels
Definitions section. The Annunciation Window
is located to the right of the Altimeter and Vertical
Speed Indicator on the display. All Cessna Nav III
annunciations can be displayed simultaneously in
the Annunciation Window. A white horizontal line
separates annunciations that are acknowledged from
annunciations that are not yet acknowledged. Higher
priority annunciations are displayed towards the top
of the window. Lower priority annunciations are
displayed towards the bottom of the window.
• Alerts Window: The Alerts Window displays alert
text messages. Up to 64 prioritized alert messages
can be displayed in the Alerts Window. Pressing
the ALERTS Softkey displays the Alerts Window.
Pressing the ALERTS Softkey a second time removes
the Alerts Window from the display. When the Alerts
Window is displayed, the pilot can use the large FMS
Knob to scroll through the alert message list.
• Softkey Annunciation: During certain alerts,
the ALERTS Softkey may appear as a flashing
annunciation to accompany an alert. The ALERTS
Softkey assumes a new label consistent with the
alert level (WARNING, CAUTION, or ADVISORY).
By pressing the softkey annunciation, the pilot
acknowledges awareness of the alert. The softkey
then returns to the previous ALERTS label. If alerts
are still present, the ALERTS label is displayed in
inverse video (white background with black text).
The pilot can press the ALERTS Softkey a second
time to view alert text messages.
• System Annunciations: Typically, a large red ‘X’
appears in windows when a failure is detected in the
LRU providing the information to the window. See
the G1000 System Annunciations section for more
information.
• Audio Alerting System: The G1000 system issues
audio alert tones when specific system conditions are
met. See the Alert Levels Definitions section for more
information.

12.1 ALERT LEVEL DEFINITIONS
The G1000 Alerting System, as installed in Cessna Nav
III aircraft, uses three alert levels.
• WARNING: This level of alert requires immediate
pilot attention. A warning alert is annunciated in
the Annunciation Window and is accompanied
by a continuous aural tone. Text appearing in the
Annunciation Window is RED. A warning alert is
also accompanied by a flashing WARNING Softkey
annunciation, as shown in Figure 12-2. Pressing
the WARNING Softkey acknowledges the presence
of the warning alert and stops the aural tone, if
applicable.
• CAUTION: This level of alert indicates the
existence of abnormal conditions on the aircraft
that may require pilot intervention. A caution alert
is annunciated in the Annunciation Window and is
accompanied by a single aural tone. Text appearing
in the Annunciation Window is YELLOW. A caution
alert is also accompanied by a flashing CAUTION
Softkey annunciation, as shown in Figure 12-3.
Pressing the CAUTION Softkey acknowledges the
presence of the caution alert.
• MESSAGE ADVISORY: This level of alert provides
general information to the pilot. A message
advisory alert does not issue annunciations in the
Annunciation Window. Instead, message advisory
alerts only issue a flashing ADVISORY Softkey
annunciation, as shown in Figure 12-4. Pressing
the ADVISORY Softkey acknowledges the presence
of the message advisory alert and displays the alert
text message in the Alerts Window.

12.8 G1000 SYSTEM MESSAGE ADVISORIES
This section describes various G1000 system message advisories. Certain messages are issued due to an LRU or an LRU
function failure. Such messages are normally accompanied by a corresponding red ‘X’ annunciation as shown previously in
the G1000 System Annunciation section.
NOTE: This section provides information regarding G1000 message advisories that may be displayed by the
system. Knowledge of the aircraft, systems, flight conditions, and other existing operational priorities must
be considered when responding to a message. Always use sound pilot judgment. The Cessna aircraft Pilot’s
Operating Handbook (POH) takes precedence over any conflicting guidance found in this section.

– Parallel track unavailable:
invalid leg type. Invalid leg type for parallel offset.
PTK FAIL
– Parallel track unavailable:
past IAF. IAF waypoint for parallel offset has been passed.
UNABLE V WPT
– Can’t reach current
vertical waypoint.
The current vertical waypoint can not be reached within the maximum flight path
angle and vertical speed constraints. The system automatically transitions to the
next vertical waypoint.
VNV
– Unavailable. Unsupported leg
type in flight plan.
The lateral flight plan contains a procedure turn, vector, or other unsupported leg
type prior to the active vertical waypoint. This prevents vertical guidance to the
active vertical waypoint.
VNV
– Unavailable. Excessive
crosstrack error. The current crosstrack exceeds the limit, causing vertical deviation to go invalid.
VNV
– Unavailable. Excessive track
angle error.
The current track angle error exceeds the limit, causing the vertical deviation to
go invalid.
VNV
– Unavailable. Parallel course
selected. A parallel course has been selected, causing the vertical deviation to go invalid.
NO WGS84 WPT
– Non WGS 84
waypoint for navigation -[xxxx]
The selected waypoint [xxxx] does not use the WGS 84 datum. Cross-check
position with alternate navigation sources.
TRAFFIC FAIL
– Traffic device has
failed.
The G1000 is no longer receiving data from the traffic system. The traffic device
should be serviced.
STRMSCP FAIL
– Stormscope has
failed. Stormscope has failed. The G1000 system should be serviced.
FAILED PATH
– A data path has failed. A data path connected to the GDU or the GIA 63/W has failed.
MAG VAR WARN
– Large magnetic
variance. Verify all course angles.
The GDU’s internal model cannot determine the exact magnetic variance for
geographic locations near the magnetic poles. Displayed magnetic course angles
may differ from the actual magnetic heading by more than 2°.
