1 GENERAL
The information in this supplement is FAA-approved and must be attached to the Pilot’s Operating
Handbook and FAA Approved Airplane Flight Manual (POH/AFM) when the airplane has been
modified by installation of the Garmin G3X Touch Electronic Flight Instrument system in accordance
with Garmin International, Inc. approved data, STC SA01899WI.
The information in this supplement supersedes or adds to the basic POH/AFM only as set forth below.
Users of the manual are advised to always refer to the supplement for possibly superseding
information and placarding applicable to operation of the airplane.
The G3X Touch provides one or more of the following functions:
•
Primary Flight Display (PFD) – Provides attitude, air data, heading, and navigation information
to the pilot.
•
Multi-Function Display (MFD) – Provides pilot awareness of factors that may affect the overall
conduct of the flight such as advanced moving map including terrain, obstacle and traffic alerts,
georeferenced FliteCharts® or Jeppesen® ChartView™ charts and SafeTaxi® airport
diagrams.
•
Engine Indication System (EIS) – Provides engine and airframe operating parameters to the
pilot.
The G3X Touch is scalable in the following configurations:
•
One GDU 470, 7” portrait touchscreen display, split screened providing both PFD and MFD
functions.
•
One GDU 460, 10” touchscreen display, split screened providing both PFD and MFD functions.
•
Two GDU 470 7” portrait touchscreen displays, one functioning as a PFD and the other as a
MFD.
•
One GDU 460 10” touchscreen display functioning as a PFD, and one GDU 470 7” portrait
touchscreen display functioning as a MFD.

These displays come with a built-in WAAS GPS receiver for VFR operations and native infrared
touchscreen interface. The system can also interface with an IFR approved GPS navigator for IFR
operations.
PFD installations require the installation of a GSU 25 ADAHRS, GMU 11 magnetometer, GTP 59
temperature probe, and the GAD 27 voltage stabilizer (14V airframes with EIS). For all PFD
installations in aircraft approved for IFR operations, standby instruments and an IFR approved
navigation system are required.
If the installation includes a separate PFD and MFD, reversionary backup is available should a failure
of either display occur. In reversionary mode, the remaining G3X Touch display combines critical flight
instrumentation with engine readouts (if installed) and navigation information in a single-screen
consolidated presentation.
If EIS functions are installed, they require the installation of a remote mounted GEA 24 Engine Airframe
unit and associated engine sensors.
MFD functions are supported by an internal GPS receiver or an external IFR GPS navigator interface.
G3X Touch flight displays can be seamlessly integrated with a variety of radios, transponders, audio
panels, ADS-B, SiriusXM ® data links, mobile devices via Garmin Connext ® and autopilot systems.
Use of this supplement requires the installation of Garmin G3X Touch Electronic Flight Instrument
hardware and system software version 8.0 or later FAA Approved software version in the aircraft.
Pilots are advised to carefully review the contents of this Airplane Flight Manual Supplement before
operating the airplane.
The following table lists the Pilot’s Guide applicable to the respective system software version.

information from the G5. An amber AHRS REVERT annunciation will be displayed
on the PFD and attitude information from the G5 will automatically be displayed on the
G3X Touch. If installed, the GFC 500 autopilot will function normally.

Attitude Aligning / Keep Wings Level
If the “ALIGNING KEEP WINGS LEVEL” indication occurs during flight, the G3X Touch has detected
an invalid attitude solution and will not display any attitude information.
1. Use standby instruments to maintain 1o nose up pitch and wings level flight. The system will
display attitude when internal accuracy tolerances have been met.
2. Limit aircraft attitude to +10o bank, +5o pitch, 200 KTAS or less.
3. If attitude does not return, continue to use the standby flight instruments for aircraft attitude
control.
3.4

7 SYSTEM DESCRIPTION
The G3X Touch System increases situational awareness by replacing the traditional instruments on
the panel with an easy-to-scan Primary Flight Display (PFD) that features a horizon, airspeed, attitude,
altitude, vertical speed, heading, and course deviation information.
7.1
Primary Flight Instruments
Attitude information is displayed over a virtual blue sky and synthetic ground with a white horizon line.
The Attitude Indicator displays the pitch (indicated by the Amber symbolic aircraft on the pitch scale),
roll, and slip/skid information.
The horizon line is part of the pitch scale. Pitch markings occur at 2.5˚ intervals through all pitch ranges.
The inverted white triangle indicates zero on the roll scale. Major tick marks at 30˚ and 60˚ and minor
tick marks at 10˚, 20˚, and 45˚ are shown to the left and right of the zero. Angle of bank is indicated by
the position of the pointer on the roll scale.
Slip/skid is indicated by the location of the ball.

The Standard Rate Turn Bank Angle Pointers are green pointers displayed on the roll scale that show
the bank angle corresponding to a standard rate turn.
Standard Rate Turn Bank Angle Pointers
The Turn Rate Indicator is located at the top of the HSI. Tick marks to the left and right of the displayed
heading denote standard turn rates (3 deg/sec). A magenta Turn Rate Trend Vector shows the current
turn rate. The end of the trend vector gives the heading predicted in 6 seconds, based on the present
turn rate. A standard-rate turn is shown on the indicator by the trend vector stopping at the standard

turn rate tick mark, corresponding to a predicted heading of 18˚ from the current heading. At rates
greater than 4 deg/sec, an arrowhead appears at the end of the magenta trend vector and the
prediction is no longer valid.
The Airspeed Indicator may be displayed as a vertical tape or a round dial. When the Airspeed
Indicator is displayed as a tape, it displays a range of 70 knots on a rolling number gauge using a
vertical tape. Numeric labels and major tick marks are shown at intervals of 10 knots. Minor tick
marks are at intervals of 5 knots. The current airspeed is displayed in the black pointer. The True
Airspeed (TAS) is displayed above the scale in white digits and the Ground Speed (GS) is displayed
below the scale in magenta digits.
The Altimeter may be displayed as a vertical tape or a round dial. When the Altimeter is displayed
as a tape, it displays 400 feet of barometric altitude values at a time on a rolling number gauge using
a moving tape. Numeric labels and major tick marks are shown at intervals of 100 feet. Minor tick
marks are at intervals of 20 feet. The current altitude is displayed in the black pointer. The barometric
pressure setting is displayed below the Altimeter in inches of mercury (in Hg) or hectopascals (hPa)
when metric units are selected.
The Selected Altitude is displayed above the Altimeter in the box indicated by a selection bug symbol.
A bug corresponding to this altitude is shown on the altimeter; if the Selected Altitude exceeds the
range shown on the tape, the bug appears at the corresponding edge of the tape.
The Altitude Alerting function provides the pilot with visual and aural alerts when approaching the
Selected Altitude. Whenever the Selected Altitude is changed, the Altitude Alerter is reset. The
following will occur when approaching the Selected Altitude:
•
Passing within 1000 feet of the Selected Altitude, the Selected Altitude (shown above the
Altimeter) flashes for 5 seconds and an aural tone is generated.
•
When the aircraft passes within 200 ft of the Selected Altitude, the Selected Altitude flashes
for 5 seconds and an aural tone is generated to indicate that the aircraft is approaching the
selected altitude.
•
After reaching the Selected Altitude, if the pilot flies outside the deviation band (±200 Feet of
the Selected Altitude), the Selected Altitude changes to Amber text on a black background,
flashes for 5 seconds, and an aural tone is generated.
The Vertical Speed Indicator (VSI) may be displayed as a tape or an arc segment. The VSI displays
the aircraft vertical speed using a non-moving tape labeled at 500, 1000 and every 1000 fpm up to the
maximum with minor tick marks every 100 feet up to 1000 fpm. The current vertical speed is displayed
using a white arrow along the scale.
7.2
Vertical Deviation Indicators
The Vertical Deviation (Glideslope) Indicator (VDI) appears to the left of the altimeter whenever an ILS
frequency is tuned in the active NAV field of an external navigator. A green diamond acts as the VDI
Indicator. The green 'G' indicates an external glideslope source. If a localizer frequency is tuned and
there is no glideslope signal, “NO GS” is annunciated.
190-01754-01 Rev. 3
FAA Approved AFMS or Supplemental AFM for the Garmin G3X Touch EFIS
P a g e | 7-3
The Vertical Deviation (Glidepath) Indicator (VDI) also appears to the left of the altimeter during a GPS
approach. The glidepath is analogous to the glideslope for GPS approaches supporting WAAS vertical
guidance (LNAV+V, L/VNAV, LPV). The Glidepath Indicator appears on the G3X Touch as a magenta
diamond. The magenta 'G' indicates a internal GPS source. If the approach type downgrades past the
final approach fix (FAF), “NO GP” is annunciated.
An external navigation source is not required to receive VNAV indications. A magenta chevron (VNAV
Indicator) to the left of the altimeter on the Vertical Deviation Scale shows the VNAV profile, and a
magenta chevron (Required Vertical Speed Indicator (RVSI)) on the Vertical Speed Indicator indicates
the required vertical speed to reach the target altitude. The magenta 'V' indicates a VNAV profile is
active.
7.3
HSI Annunciations
Some or all HSI annunciations may appear in the four quadrants of the G3X Touch HSI depending on
the external navigator(s) configured.
Amber LOI – Loss of GPS integrity
Amber or Magenta VFR – An external GPS source is configured but there is not enough guidance
data for IFR use.
Amber REV – External navigation source failed. Reverted to internal VFR GPS for navigation.
Amber MSG – External navigation source has a pending message
Cyan INT – The pilot has elected to use the internal GPS navigation source instead of the external
GPS navigation source.
7.4
Course Deviation Indicator (CDI)
The HSI contains a Course Deviation Indicator (CDI), with a Course Pointer, To/From Indicator, and a
sliding deviation bar and scale. The course pointer is a single line arrow (GPS1, VOR1, and LOC1) or
a double line arrow (GPS2, VOR2, and LOC2) which points in the direction of the set course. The
To/From arrow rotates with the course pointer and is displayed when the active NAVAID is received.
The Course Deviation Indicator (CDI) moves left or right from the course pointer along a lateral
deviation scale to display aircraft position relative to the course. If the course deviation data is not
valid, the CDI is not displayed.
Another Lateral Deviation Scale and combination Course Deviation and To/From Indicator is located
below the slip/skid indicator.
FAA Approved AFMS or Supplemental AFM for the Garmin G3X Touch EFIS
P a g e | 7-4
190-01754-01 Rev. 3
Lateral Deviation Indication
The CDI can display two sources of navigation: GPS or NAV (VOR, localizer) depending on the
external navigator(s) configured. Color indicates the current navigation source: magenta (for GPS)
or green (for VOR and LOC). The full-scale limits for the CDI are defined by a GPS-derived distance
when coupled to GPS. When coupled to a VOR or localizer (LOC), the CDI has the same angular
limits as a mechanical CDI. If the CDI exceeds the maximum deviation on the scale (two dots) while
coupled to GPS, the crosstrack error (XTK) is displayed below the white aircraft symbol.
In addition to the flight instruments, the PFD also displays supplemental information, including the
Outside Air Temperature (OAT), wind data, User Timer, and G-Meter.
7.5
Engine Indication System
The G3X Touch EIS displays engine, electrical, and other system parameters. Additional EIS
information can be viewed by selecting the Eng Page on the MFD.
Green bands on the instruments indicate normal ranges of operation; amber and red bands indicate
caution and warning, respectively. When unsafe operating conditions occur, the corresponding caution
readout will display solid Amber and the warning readout will flash red. If sensory data to an instrument
becomes invalid or unavailable, a red “X” is displayed across the instrument.
7.6
Communication / Navigation / Surveillance System
The Communication/Navigation/Surveillance (CNS) system includes the audio interface,
communication radios, navigation radios, and Mode S transponder. These functions can be accessed
from the boxes that make up the CNS Data Bar located at the top of the PFD and/or MFD.
CNS Data Bar
7.7
Remote Transponder Interface
The G3X Touch is capable of interfacing with several remote transponders providing Mode S
interrogation and reply capabilities. Transponder tuning for panel mount transponders is also
supported.
Ground Mode
Ground Mode is normally selected automatically when the aircraft is on the ground. The transponder
powers up in the mode it was in when shut down. A green GND indication and transponder code
appear in the mode field of the Transponder Data Box. In Ground Mode, the transponder does not
190-01754-01 Rev. 3
FAA Approved AFMS or Supplemental AFM for the Garmin G3X Touch EFIS
P a g e | 7-5
allow Mode A and Mode C replies, but it does permit acquisition squitter and replies to discretely
addressed Mode S interrogations.
Standby Mode (Manual)
In Standby, the transponder does not reply to interrogations, but new codes can be entered. When
Standby Mode is selected, a white STBY indication and transponder code appear in the mode field of
the Transponder Data Box.
ON Mode can be selected at any time. ON Mode generates Mode A and Mode S replies, but Mode C
altitude reporting is inhibited. In ON Mode, a green ON indication and transponder code appear in the
mode field of the Transponder Data Box.
Altitude Mode (Automatic or Manual)
ALT Mode is automatically selected when the aircraft becomes airborne. When the aircraft is on the
ground, the transponder automatically selects and displays GND. ALT Mode may also be selected
manually.
If Altitude Mode is selected, a green ALT indication and transponder code appear in the mode field of
the Transponder Data Box, and all transponder replies requesting altitude information are provided
with pressure altitude information.
Reply Status
When the transponder sends replies to interrogations, a green R indication appears momentarily in
the Transponder Data Box.
IDENT Function (GDU 460 and GDU 470)
Touching IDENT sends a distinct identity indication to Air Traffic Control (ATC). The indication
distinguishes the identing transponder from all the others on the air traffic controller’s screen. After
touching IDENT the bar on the button turns green momentarily.
7.8
Minimum Altitude Display and Alerting
When enabled by the pilot, an altitude minimums bug will be displayed in cyan on the barometric altitude tape.
Altitude minimums are accessed under the PFD Options Menu  Minimums sub menu and can be set by
touchscreen keypad or dual-concentric knob.
Both visual and aural altitude minimums alerts are provided. During a descent to minimums, the minimums bug
will change from cyan to white when the aircraft descends to within 100 ft of minimums. An aural “Minimums,
Minimums” alert will be triggered when the aircraft’s altitude descends through minimums and the minimums bug
will change to Amber. As the aircraft altitude climbs back above minimums, the minimums bug will change to
white 50 ft above minimums and cyan 150 ft above minimums. Alerting is rearmed once the aircraft is 150 ft or
more above the minimum’s altitude.
If a new approach is loaded into the external navigator, the Minimums Altitude display is not automatically
updated with the new approach minimums. The pilot must update the Minimums Altitude Display with the
MDA/DH for the approach loaded into the navigator.
