Section 1. GENERAL
The G5 Electronic Flight Instrument is an electronic instrument which displays primary attitude, slip and turn rate
information to the pilot. It also contains secondary indications of airspeed, altimeter and ground track. In case of a
loss of aircraft electrical power, a backup battery sustains the G5 attitude for up to four hours.
The primary function of the attitude indicator is to provide attitude information to the pilot. When installed in place
of the rate of turn indicator, the primary function of the G5 is to provide turn rate and slip ball information to the
pilot.
Section 2. LIMITATIONS
2.1
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
2.2
Software Version
2.40
Use of Secondary Instruments
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.
2.3
Kinds of Operations
No Change.

Section 3. EMERGENCY PROCEDURES
3.1
Emergency Procedures
3.1.1 G5 Failure Indications
When 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.
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.
2.
Use standby instruments.
Seek VFR conditions or land as soon as practical.
3.1.2 Attitude Aligning
During system initialization, the G5 displays the message ‘ALIGNING’ over the attitude indicator. The G5 should
display valid attitude typically within the first minute of power-up. The G5 can align itself both while taxiing and
during level flight.
If the attitude “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
message to clear.
3.1.3 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.
2.
Use standby instruments to maintain wings level flight. The system will display attitude when internal
accuracy tolerances have been met.
If attitude does not return, seek VFR conditions or land as soon as practical.

3.1.4 Loss of Electrical Power
In the event of a loss of aircraft electrical power to the G5, the indicator will continue to function on its internal
battery. 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.
3.2
System messages
The G5 has the capability to display system messages to the crew along the bottom of the display. The following
table shows the meaning of each message. System messages are displayed in white text.
Message
External Power Lost
Critical battery fault!
Powering off…
Battery fault
Meaning
Aircraft power has been removed from the G5
Battery has critical fault condition and the unit is about to power off to avoid
damage to the battery.
Battery has a fault condition - contact Garmin if it persists.
Battery charger fault
Low battery
Hardware fault
Power supply fault
Unit temperature limit
exceeded
Network address
conflict
Communication error
Battery charger has a fault condition - contact Garmin if it persists.
Battery charge level is low
Unit has a hardware fault - contact Garmin for service
Unit power supply fault detected - contact Garmin for service if it persists
Unit is too hot or too cold
Factory calibration data
invalid
Magnetic field model
database out of date
Using external GPS data
Another G5 with the same address is detected on the network (most commonly a
wiring error on one of the units)
General communication error (most commonly appears in conjunction with
Network Address Conflict message)
Unit calibration data not valid - return to Garmin
Internal magnetic field database is out of date - software update required
GPS data from another network LRU is being used. The unit's internal GPS
receiver is enabled, but unable to establish a GPS fix
No specific pilot action is required for any of the displayed system messages. As long as attitude is displayed, the
system is adequate for flight in instrument conditions.
These messages remain while the condition persists, or until cleared by pressing the knob.

Section 4. NORMAL PROCEDURES
4.1
G5 Power Button and Knob
The G5 display will power on with the application of aircraft power. The G5 power button is used to turn the
display on and off. Press and hold the power button to turn the display off.
The knob is used to adjust the baro setting on the secondary display of altitude.
Pressing the knob provides access to a menu, allowing the entry of altitude preselect or desired track information. A
subsequent press of the knob will remove the menu.
4.2
Backlight Intensity Adjustment
The power up state of the G5 backlight is in Auto adjustment mode.
To adjust the backlighting:
To select manual mode from Auto mode:

Prior to Flight in Instrument Conditions
1.
Verify the battery status indicator is green.
Section 5. PERFORMANCE
No change.
Section 6. WEIGHT AND BALANCE
See current weight and balance data.
Section 7. SYSTEM DESCRIPTIONS
Refer to Garmin G5 Pilot’s Guide P/N 190-01112-12 for a description of the G5 electronic flight instrument. This
reference material is not required to be on board the aircraft but does contain a more in depth description of all the
functions and capabilities of the G5.
The ATT circuit breaker supplies power to the G5 instrument for normal power operation and to charge the internal
battery.
