G500 Failures & Partial-Panel - ATP Electronics Piper Archer Training Supplement

Standby Altimeter & Airspeed Indicator
The pitot-static system provides information to the standby altimeter and
airspeed indicator.
G500 Failures & Partial-Panel Approaches
For partial-panel training and checkrides, the two most common training
scenarios are simulated AHRS failure and PFD failures.
Failure Condition
AHRS Failure
PFD Failure
Electrical Failure
ADC Failure
Attitude & Heading Reference System (AHRS) Failure
Indications:
1. The sky/ground presentation is removed.
2. A red X appears across the Attitude Direction Indicator (ADI).
3. Yellow "ATTITUDE FAIL" and "HDG" alert messages appear on the PFD.
4. A "TRK" message appears to the right of the ground track at the top of
the compass rose.
5. Rate-of-turn information is unavailable.
6. "HDG LOST", "HDG FAULT", and "TRK TRAFFIC" alert messages appear
on the MFD.

Circuit breaker-simulated failures are prohibited in ATP aircraft.
Piper and Garmin advise against pulling circuit breakers as a
means of simulating failures on the Garmin G500 system. Pulling
circuit breakers, or using them as switches, has the potential to
weaken the circuit breaker to a point at which it may not perform
its intended function. Also reference Advisory Circulars 120-80,
23-17B, and 43.13-1B.
