EFIS P a g e | 1-1 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 the installation of the Garmin G3X Touch Electronic Flight Instrument System in accordance with 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 with a variety of configurations made up of the 7” portrait GDU 470 and the 10” landscape GDU 460. Installations may consist of one or both display types in any combination from one to three displays (or up to four displays total in tandem cockpit aircraft). A minimum installation with a single display may be a standalone MFD or a PFD which can be split screened to provide both PFD and MFD functions. EIS can optionally be displayed on any GDU except a 7” portrait PFD. Only one display per cockpit can be installed as a PFD (any second or third display is an MFD). AFMS or Supplemental AFM for the Garmin G3X Touch EFIS 190-01754-01 Rev. 5 P a g e | 1-2 Single 7” Portrait GDU (PFD with MFD in split mode, No EIS) Single 10” GDU (PFD & MFD, EIS Optional) 190-01754-01 Rev. 5 AFMS or Supplemental AFM for the Garmin G3X Touch EFIS P a g e | 1-3 Dual 7” Portrait GDUs (PFD & MFD, EIS Optional) One 10” + One 7” Portrait GDU (PFD & MFD, EIS Optional) AFMS or Supplemental AFM for the Garmin G3X Touch EFIS 190-01754-01 Rev. 5 P a g e | 1-4 The PFD has an internal WAAS GPS receiver for VFR operations and a touchscreen interface. The G3X Touch system also can interface with an external, IFR approved navigator for IFR operations. Aircraft without an external, IFR approved navigator are approved for VFR operations only. Refer to equipment requirements for IFR operations in Limitations Section 2.3, Navigation Systems for IFR Operations, and the table in Section 2.24, Kinds of 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 connection to an external, IFR approved GPS navigator. G3X Touch flight displays can be integrated with a variety of systems including VHF radios, transponders, audio panels, ADS-B, SiriusXM® data links, mobile devices via Garmin Connext® and autopilot systems. Carefully review the contents of this Airplane Flight Manual Supplement before operating the airplane. Also review Pilot’s Guide 190-02472-00 Rev A, or later version applicable to the approved software version of the G3X Touch system installed on the aircraft. The Pilot’s Guide provides details on the features of the G3X Touch system. USE OF THE AFMS The following definitions apply to WARNINGS, CAUTIONS and NOTES found throughout the AFMS: WARNING Operating procedures, techniques, etc., which could result in personal injury or loss of life if not carefully followed.

The functions described in this section may not be available in all aircraft depending on installed equipment and interfaces. A minimum installation with a single display may be a standalone MFD or a PFD which can be split screened to provide both PFD and MFD functions. Optional functions include EIS, datalink traffic and weather, AOA, autopilot interface, remote audio panel, GPS/NAV/COM interface, transponder interface, and others. 7.1 Primary Flight Instruments When a PFD is installed, 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. Bezel Overview (GDU 460) AFMS or Supplemental AFM for the Garmin G3X Touch EFIS 190-01754-01 Rev. 5 P a g e | 7-2 Bezel Overview (GDU 470) NRST Key Press to display the Nearest Page for viewing the nearest airports, intersections, NDBs, VORs, waypoints, frequencies, and airspaces Direct- To Key Press to activate the Direct-To function, enter a destination waypoint establish a direct-to course to the selected destination MENU Key Press once to view the Page Menu Press twice to view the Main Menu Press a third time to clear the Main Menu enabled. BACK Key Press to return to the previous screen Press and hold to return to the default MFD Page 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 190-01754-01 Rev. 5 AFMS or Supplemental AFM for the Garmin G3X Touch EFIS P a g e | 7-3 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 feet 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. AFMS or Supplemental AFM for the Garmin G3X Touch EFIS 190-01754-01 Rev. 5 P a g e | 7-4 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. Vertical Deviation Indicator (Glideslope – ILS Source) 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 GPS source. If the approach type downgrades past the final approach fix (FAF), “NO GP” is annunciated. Vertical Deviation Indicator (Glidepath – GPS Source) 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. 190-01754-01 Rev. 5 AFMS or Supplemental AFM for the Garmin G3X Touch EFIS P a g e | 7-5 VNAV Indicator 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. AFMS or Supplemental AFM for the Garmin G3X Touch EFIS 190-01754-01 Rev. 5 P a g e | 7-6 CDI and 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 Display of PFD information on MFD MFDs installed as part of the G3X touch system can display PFD information if manually selected by the pilot, or will automatically do so if the installed PFD display fails. The display of PFD information on an MFD is a duplication of the original PFD information and is not an independent compilation of data from other sources. To manually display backup PFD information on an MFD: 1. On the MFD, press the MENU button twice. 2. Select Setup. 3. Select Display. 4. On a 7” GDU 470, set Full MFD/PFD Toggle to Enabled. On a 10” GDU 460, set MFD Split Screen Page to PFD. 5. Press and hold the BACK button to close the Display Setup window and return to MFD display. 6. On a 7” MFD, touch the PFD button in the upper corner to select the backup PFD display. On a 10” MFD, touch the Split button in the upper corner to select the backup PFD display. 190-01754-01 Rev. 5 AFMS or Supplemental AFM for the Garmin G3X Touch EFIS P a g e | 7-7 7.6 Engine Indication System The G3X Touch EIS (if installed) displays engine, electrical, and other system parameters. Gauges required to be displayed full time are located on the Main Engine Display which is always in view. Additional EIS information can be viewed on the Eng Page which can be selected by touching the Main Engine Display or by turning the ‘Select Page’ knob to the right on an MFD window. 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. Most EIS caution and warning conditions also generate an alert message on the PFD, including gauges that may appear only on the Eng Page. An aural alert is also issued with a flashing red warning. If sensor data for an instrument becomes invalid or unavailable, a red “X” is displayed across the instrument. 7.7 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 7.8 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 and Altitude Modes Most Garmin transponders automatically transition between on-ground and in-air and operate in the appropriate mode at all times. No pilot action is required to manage modes unless there is a need to manually select STBY or ON modes. G3X displays a green GND indication and transponder code in the Transponder Data Box while on- ground, and a green ALT indication when in-air, when not set to STBY or ON. NOTE Some panel mount transponders may indicate ALT on their dedicated display at all times, even while on-ground. As a result, in some installations, the transponder display and G3X display will indicate different modes while on the ground, although they are functionally equivalent. Standby Mode (Manual) When Standby mode is selected, the transponder does not reply to interrogations, but new codes can be entered. A white STBY indication and transponder code appear in the Transponder Data Box. Some transponders will automatically transition from STBY to ALT mode when the aircraft transitions from on-ground to in-air. AFMS or Supplemental AFM for the Garmin G3X Touch EFIS 190-01754-01 Rev. 5 P a g e | 7-8 On Mode (Manual) 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 Transponder Data Box. Reply Status When the transponder sends replies to interrogations, a green R indication appears momentarily in the Transponder Data Box. IDENT Function 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. 7.9 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. 7.10 AOA Probe The G3X Touch PFD will display angle of attack from the GAP 26 AOA probe if installed. The GSU 25 uses the pressure from the GAP 26 probe and the pitot/static pressures it already receives from the existing aircraft pitot/static system to determine the aircraft’s angle of attack (AOA). The AOA indications and warnings presented on the G3X system are for reference only and are not intended as replacements for the aircraft’s original stall warning system. The AOA stall warning margin and indications may not be the same at different flap settings and are only supported for positive G flight. 7.11 GAD 27 Wig Wag The GAD 27 module (if installed) provides a feature that provides the ability to flash the Landing and Taxi lights of the airplane in an alternating fashion, otherwise known as “Wig Wag”. Two 3-position switches control this feature, one for the landing lights and one for the taxi lights: • ON – Respective light is on • FLASH – Respective light will flash • OFF – Respective light is off 190-01754-01 Rev. 5 AFMS or Supplemental AFM for the Garmin G3X Touch EFIS P a g e | 7-9 When both switches are in the FLASH position, the landing and taxi lights alternate off and on with each other to produce the ‘Wig-Wag’ effect. Before landing, switch to ON for steady landing lights. 7.12 EIS Caution / Warning Lights If the G3X EIS display is outside the pilot’s primary field of view and a PFD is not installed to provide EIS annunciations, discreet Caution/Warning lights are installed. The lights are installed in the primary field of view and are labeled ENGINE. Only a G3X EIS exceedance from a gauge on the Main EIS Display triggers the EIS Caution/Warning lights. EIS gauges that are not on the Main EIS Display do not alert. 7.13 Smart Glide When installed with a Garmin GTN Xi with Smart Glide enabled, the G3X Touch will provide Smart Glide map indications, annunciation of GLIDE, and Emergency Page data for the Smart Glide feature. If displayed, the G3X Touch Glide Range Ring will be removed when Smart Glide is active. Refer to GTN Xi glide range ring display. For more details on the Smart Glide function, refer to the GTN Xi Pilot’s Guide (190-02327-03, revision D or later) and GTN Xi AFMS (P/N 190-01007-C2 or 190-01007- C3, revision 4 or later).
