GARMIN G5 Electronic Flight Instrument
SYSTEM DESCRIPTION
G5 Electronic Flight Instrument
The G5 Electronic Flight Instrument contains integrated attitude/air data sensors that provide display of attitude and secondary display of air data information. The G5 features a bright, sunlight readable, 3.5-inch color display. In the case of aircraft power loss, the G5 battery sustains the G5 flight display with up to 4 hours of power

OPERATION
G5 Annunciations
When a G5 function fails, a large red ‘X’ is 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.
G5 Failure Indications
G5 Attitude
The G5 calculates aircraft attitude using information from its built-in inertial sensors. The G5 also uses GPS and airspeed data to provide the most accurate attitude information. The G5 should display valid attitude within the first minute of power-up.
If the G5 senses that the attitude solution is valid, but not yet within the internal accuracy limits, “ALIGNING” is displayed. The displayed attitude information is still accurate and usable while this indication is shown. The G5 can align itself both while taxiing and during level flight.
Attitude Aligning Indication
If the G5 senses that the attitude solution is invalid, “ALIGNING KEEP WINGS LEVEL” is displayed. No attitude information is displayed while this indication is shown. The G5 can align itself both while taxiing and during level flight.
Attitude Aligning Keep Wings Level Indication
If the G5 inertial sensors fail, “ATTITUDE FAIL” is displayed in addition to a red-X flag. No attitude information is displayed while this indication is shown.
Attitude Failure Indication
Backlight Intensity
When set to Auto, the backlight is automatically adjusted according to ambient light conditions. When set to Manual, the backlight level is set by the pilot.
Adjusting backlight intensity:
- While the unit is turned on, press the Power Button.
- Turn the Knob to adjust the backlight intensity.
- Press the Knob to close the backlight page.
Setting the backlight intensity to automatic:
- While the unit is turned on, press the Power Button.
- Press the Power Button again to select Auto.
- Press the Knob to close the backlight page.

Airspeed Indicator
NOTE:
The G5 speed Reference values depend upon the aircraft’s specific system configuration and may vary from the examples discussed in this section.
The Airspeed Indicator displays airspeed on a rolling number gauge using a moving tape. The numeric labels and major tick marks on the moving tape are marked at intervals of 10 MPH or KT, as indicated at bottom of airspeed tape). The actual airspeed is displayed inside the black pointer. The pointer remains black until reaching never-exceed speed (VNE), at which point it turns red.
A color-coded (red, white, green, yellow, and red/white “barber pole”) speed range strip is located on the moving tape. The colors denote flaps operating range, normal operating range, caution range, and never-exceed speed (VNE). A red range is also present for low speed awareness.
The Airspeed Trend Vector is a vertical, magenta line, extending up or down on the airspeed scale, shown to the right of the color-coded speed range strip. The end of the trend vector corresponds to the predicted airspeed in 6 seconds if the current rate of acceleration is maintained. If the trend vector crosses VNE, the text of the actual airspeed readout changes to yellow. The trend vector is absent if the speed remains constant or if any data needed to calculate airspeed is not available due to a system failure.
Airspeed Indicator
Vspeed Reference
Attitude Indicator
Attitude information is displayed over a virtual blue sky and brown ground with a white horizon line. The Attitude Indicator displays the pitch (indicated by the yellow 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. When the aircraft enters an unusual pitch attitude, red extreme pitch warning chevrons pointing toward the horizon are displayed on the Attitude Indicator starting at 60˚ above and 40˚ below the horizon line.
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.
Vspeed references including VNE, Vno, Vso, Vs1, Vfe, Va, Vx, Vy , VYse, Vg, Vr, are displayed on the G5 (as configured during installation.)
When airspeed is present, the speeds configured are displayed at their respective locations to the right of the airspeed scale; otherwise, the speeds are displayed at the bottom of the airspeed indicator.

Altimeter
The Altimeter 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 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 tape. If the Selected Altitude exceeds the range shown on the tape, the bug appears at the corresponding edge of the tape.
Setting the selected altitude:
- Press the Knob to display the Menu.
- Select Altitude and use the Knob to change the Selected Altitude.
Syncing to the current altitude:
- Press the Knob to display the Menu.
- Select Altitude and press and hold the Knob to sync the Selected Altitude to the current altitude.
Altimeter
Barometric Pressure
The barometric pressure setting is displayed below the Altimeter in inches of mercury (in Hg).
Selecting the altimeter barometric pressure setting:
Turn the Knob to set the barometric pressure.
Altitude Alerting
The Altitude Alerting function provides the pilot with a visual alert 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:
Altitude Alerting Visual Annunciation
- Passing within 1000 feet of the Selected Altitude, the Selected Altitude (shown above the Altimeter) flashes for 5 seconds.
- When the aircraft passes within 200 ft of the Selected Altitude, the Selected Altitude flashes for 5 seconds 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 yellow text on a black background, flashes for 5 seconds
Turn Rate Indicator
The Turn Rate Indicator is located at the bottom of the PFD Page. A magenta Turn Rate Trend Vector shows the current turn rate. A standard-rate turn (3 deg/sec) is shown on the indicator by the trend vector stopping at the standard turn rate tick mark
Turn Rate Indicator
Ground Track
A Ground Track Tape is displayed at the top of the PFD Page and displays
numeric labels every
10°. Major tick marks are at 5° intervals and minor tick marks at 1°
intervals.
When displaying Ground Track, a magenta bug is displayed on the tape.
Adjusting the selected ground track:
- Press the Knob to display the Menu.
- Select Track and use the Knob to change the Selected Track.
Syncing to the current ground track:
- Press the Knob to display the Menu.
- Select Track and press and hold the Knob to sync the selected ground track to the current ground track.
Selected Ground Track
Vertical Speed Indicator (VSI
The Vertical Speed Indicator displays the aircraft vertical speed using a non- moving tape to the right of the altimeter. The current vertical speed is displayed using a white arrow along the tape.
Vertical Speed Indicator
Battery Status Indicator
The current charge level of the battery is indicated by the filled-in portion of the battery icon. The battery icon turns yellow or red to indicate a low- battery condition.
When the G5 is powered by the battery, the estimated time until the battery is empty is displayed in hours and minutes. Otherwise, the current charge level of the battery in percent is displayed as a numeric value.
When the G5 is connected to external power and the battery is being charged, a lightning bolt symbol appears over the battery icon.
Other battery indications:
| Battery charger hardware fault, or temperature too high or low to charge
the battery safely
---|---
| Battery fault
| Battery is not present
