rate and slip ball information to the pilot. When installed in place of the directional gyro, the primary function of the G5 is to provide directional information to the pilot. NOTE: The pilot is reminded to perform appropriate flight and navigation instrument cross checks for the type of operation being conducted. In case of a loss of aircraft electrical power, a backup battery (optional when installed as a DG/HSI) sustains the G5 Electronic Flight Instrument for up to four hours. An optional GAD 29B/GAD 29D may be installed to provide course and heading datum to an autopilot based on the data selected for display on the HSI. An optional GAD 13 and OAT probe may be installed to provide measured outside air temperature (OAT) to the G5 for display of true airspeed (TAS), outside air temperature, winds, and density altitude. This STC allows the removal of the aircraft's vacuum system if it is not required to support any other airframe system. 190-01112-13 Rev. 8 AFMS, Garmin G5 AML STC Page 1-1 Abbreviations and Terminology The following glossary is applicable within the airplane flight manual supplement ADI Attitude Direction Indicator Airplane Flight Manual Supplement Attitude Course Deviation Indicator AFMS ATT CDI DG Directional Gyro DR FAA GPS GPSS HDG HSI ILS LOC LOI OAT TAS Dead Reckoning Federal Aviation Administration Global Positioning System GPS Roll Steering Heading Horizontal Situation Indicator Instrument Landing System Localizer (no glideslope available) Loss of Integrity Outside Air Temperature True Airspeed VFR Visual Flight Rules VHF Very High Frequency VOR VHF Omni-directional Range AFMS, Garmin G5 AML STC Page 1-2 190-01112-13 Rev. 8 - SECTION 2 – LIMITATIONS System Software Requirements The G5 must utilize the following or later FAA approved software versions for this AFMS revision to be applicable: Component G5 Electronic Flight Instrument Use of Secondary Instruments Software Version 8.00 The original type design approved instruments for airspeed, altitude and vertical speed remain the primary indications for these parameters. If the G5 Electronic Flight Instrument is installed in place of the rate of turn indicator, the original type design approved instrument for attitude remains in the primary indication for attitude. If the G5 Electronic Flight Instrument is installed in place of the directional gyro, the original type design approved instruments for attitude remains the primary indication for attitude. NOTE: For aircraft approved for VFR-only operations, the G5 Electronic Flight Instrument may be installed as an attitude indicator and rate of turn indicator. Kinds of Operations No Change except for the following: • When a portable navigation source is selected on the G5, it shall not be used for the primary means of navigation for IFR operations. 190-01112-13 Rev. 8 FAA APPROVED AFMS, Garmin G5 AML STC Page 2-1 This page intentionally left blank. AFMS, Garmin G5 AML STC Page 2-2 190-01112-13 Rev. 8 FAA APPROVED SECTION 3 - EMERGENCY PROCEDURES G5 Failure Indications If a G5 function fails, a large red 'X' is typically displayed over the instrument(s) or data experiencing the failure. Upon G5 power-up, certain instruments remain invalid as equipment begins to initialize. All instruments should be operational within one minute of power-up. If any instrument remains flagged and it is not likely an installation related problem, the G5 should be serviced by a Garmin-authorized repair facility. GPD FAIL IIISQ w Wa A R F ATTITUDE FAIL L T F SA 1 A PI EL MOCL T U L D E - CS HDG Attitude Failure Attitude failure is indicated by removal of the sky/ground presentation, a red X, and a yellow "ATTITUDE FAIL" on the display. Rate-of-turn and slip information will not be available. 1. Use standby instruments. 2. Seek VFR conditions or land as soon as practical. Heading Failure, Loss of Magnetometer Data, or Magnetic Field Error A heading failure, loss of magnetometer data, or magnetic field error is indicated by removal of the digital heading readout, a red X, and a yellow "HDG" on the display. 1. Use standby magnetic compass. NOTE: If the G5 DG/HSI has a valid GPS signal the G5 DG/HSI instrument will display the GPS track information in magenta. 190-01112-13 Rev. 8 FAA APPROVED AFMS, Garmin G5 AML STC Page 3-1 GPS Failure If GPS navigation receivers and/or navigation information are not available or invalid, the G5 will display Dead Reckoning mode (DR) or Loss of Integrity mode (LOI) on the HSI in the lower left corner. If Alternate Navigation Sources (ILS, LOC, VOR) Are Available: 1. Use alternate navigation source. If No Alternate Navigation Sources Are Available: If DR is Displayed on HSI: 1. Use the amber CDI for course information. 2. Fly toward known visual conditions. If LOI is Displayed on HSI: 1. Fly toward known visual conditions. For aircraft equipped with a GAD 29B/GAD 29D interfaced to an autopilot, GPSS will be displayed in amber text when GPSS emulation has been selected from the G5 menu. 1. Deselect GPSS from the G5 menu and select a different autopilot mode. Attitude Aligning During system initialization, the G5 displays the message 'ALIGNING' over the attitude indicator. The G5 will typically display valid attitude within the first minute of power-up. The G5 can also align itself while taxiing and during level flight. If the "ALIGNING" indication occurs during flight and attitude remains displayed, the attitude display is acceptable for use for flight in instrument conditions. The message will clear when the attitude solution is within the systems internal accuracy tolerances. It is recommended to maintain wings level to reduce the time for the system to align. Attitude Aligning / Keep Wings Level If the "ALIGNING KEEP WINGS LEVEL" indication occurs during flight, the G5 has detected an invalid attitude solution and will not display any attitude information. 1. Use standby instruments to maintain wings level flight. The system will display attitude when internal accuracy tolerances have been met. 2. If attitude does not return, seek VFR conditions or land as soon as practical. Loss of Electrical Power to the G5 Display In the event of a loss of aircraft electrical power to the G5 attitude display, the indicator will continue to function on its internal battery. If an internal battery is installed on the optional G5 HSI, the indicator will continue to function on the internal battery if aircraft power is lost. Internal battery endurance is indicated on the G5 display in hours and minutes. The charging symbol will be removed and the internal battery will not be charged. In the event the G5 attitude display powers down, the optional G5 HSI will automatically revert to displaying attitude information. It will not revert back to the DG/HSI format if the G5 attitude unit regains power. The DG/HSI presentation may be selected from the G5 menu on the G5 DG/HSI unit after reversion to the attitude display. | AFMS, Garmin G5 AML STC Page 3-2 190-01112-13 Rev. 8 FAA APPROVED Loss of Electrical Power to the GAD 29B/GAD 29D (If Installed) In the event of a loss of aircraft electrical power to the optional GAD 29B/GAD 29D, the heading and course datum will be unavailable to the autopilot and the autopilot may deviate from the intended path or may disconnect. GPS flight plan course information may be displayed on the HSI and VFR will be displayed in amber text on the HSI. GPSS will be displayed in amber text, if GPSS mode is selected. 009 } N 3 33 6 30 VPR E - W 12 24 15 21 S 1 DIST NM 1. Deselect GPSS from the G5 menu and select a different autopilot mode. 2.

Loss of Electrical Power to the GAD 13 (If Installed) In the event of a loss of aircraft electrical power to the optional GAD 13, the OAT and TAS indications will be replaced with a red X. The Density Altitude indication will be removed, and "No Wind Data" will be displayed in the wind field.
