AHRS Failure
Indications
- Failure of the Attitude
and Heading Reference System (AHRS)
is indicated by a removal of the sky/
ground presentation, a red X across
the Attitude Indicator, and a yellow
“ATTITUDE FAIL” and “HDG” messages
on the PFD. Rate-of-turn information
will not be available.
Pilot Action
- Use standby attitude
indicator for attitude info and a
combination of the magnetic compass
and Garmin GNS 430 for heading. The
CDI will function normally.
Heading Failure
Indications
- A complete Heading
Failure (magnetometer and GPS
ground track failure) is indicated by
the digital heading presentation
being replaced with a red X and
the compass rose digits being
removed.
Pilot Action
- Use the magnetic
compass and the GNS 430s for
heading information.
ADC Failure
Indications
- Complete loss of the Air
Data Computer (ADC) is indicated
by a red X and yellow text over the
airspeed, altimeter, vertical speed,
TAS and OAT displays. True airspeed
and wind calculations are also lost.
Pilot Action
- Use standby airspeed
indicator and altimeter for speed
and altitude data. There is no backup
for the VSI, but known pitch attitudes
using the attitude indicator, power
settings, and airspeeds produce
consistent descent rates.
Electrical Failure
Indication
- In the event of a total loss of electrical
power, the G500 system will be inoperative / dark.
The STBY PWR button on the standby attitude
indicator will begin blinking indicating it will turn off
in one minute.
Pilot Action
- For attitude reference,
press the “STBY
PWR” button on the standby attitude indicator
while blinking to operate using its integral
emergency battery.
If the red warning flag appears
on the standby attitude instrument face, the unit is
powered off or inoperative and must not be used.
Use the standby airspeed, altimeter, compass, and
GNS430 for remaining flight data.
