SAMPLE SYSTEM OPERATION/FAILURE MODE SCENARIOS FOR FAA-S-8081-4D
AREAS OF OPERATION SECTION IV: RECOMMENDATIONS FOR FAILURE SIMULATION
The tasks listed in this section cover flight by reference to instruments. According to the PTS, the examiner is expected to evaluate
the applicant' s use of the backup instruments with both a full panel and a partial panel. In the case of the G1000-equipped aircraft,
failures can be simulated in two ways. The preferred method is to use the dimming controls on the G1000 system combined with the
reversionary mode button on the lower portion of the GMA 1347 audio panel. The other, less desirable method consists of pulling
various circuit breakers.
NOTE: It is important to follow the aircraft manufacturer's recommendations for failure simulation, for they supersede any
guidance provided in this document.
Using the dimming controls and the reversionary mode is straightforward.
To dim the displays:
Press the MENU key on the PFD (while no other data windows are active) to display the Setup Menu window.
1.
Turn the large FMS knob to select the display to be dimmed ('PFD DSPL' or 'MFD DSPL').
2.
3.
Turn the small FMS knob to switch dimming from 'AUTO' to 'MANUAL' mode and press the ENT key.
4.
Turn the small FMS knob counterclockwise to decrease the display brightness.
To put the displays in reversionary mode:
Press the DISPLAY BACKUP button located at the bottom of the GMA 1347 audio panel.
1.
The following table shows typical configurations using the display dimming function to simulate failures.
Failure to Be Simulated
Loss of primary flight instruments on the PFD
(AHRS, ADC failure)
Complete loss of PFD
Loss of MFD
NOTE: Appropriate use of the autopilot should be observed to reduce pilot workload and maintain positive control of the
aircraft. It is important to verbally quiz the applicant on the operation of the autopilot based upon the data presented in
the table associated with the use of pulling circuit breakers (see following page).
