ABNORMAL OPERATION
REVERSIONARY MODE
If the system detects an MFD failure, reversionary mode is entered automatically.
Reversionary mode must be entered manually in the case of a PFD failure. In reversionary
mode, critical flight instrumentation is combined with engine instrumentation on the
remaining display.
Manual activation of reversionary display mode is accomplished by pressing the
appropriate DISPLAY BACKUP Button on the instrument panel.
• PFD1 – By pressing the DISPLAY BACKUP Button on the left.
• MFD – By pressing the DISPLAY BACKUP Button on the left or the right.
• PFD2 – By pressing the DISPLAY BACKUP Button on the right.
NOTE: The Piper PA-46 Mirage/Matrix Pilot’s Operating Handbook (POH)
always takes precedence over the information found in this section.
ABNORMAL COM OPERATION
When a COM tuning failure is detected by the system, the emergency frequency
(121.500 MHz) is automatically loaded into the active frequency field of the COM
radio for which the tuning failure was detected. In the event of a failure of both PFDs,
the emergency frequency (121.500 MHz) automatically becomes the active frequency
on both COM radios.
AUDIO PANEL FAIL-SAFE OPERATION
If there is a failure of the Audio Panel, a fail-safe circuit connects the pilot’s headset
and microphone directly to the COM1. Audio is not available on the speaker during
fail-safe operation. Fail-safe operation may be tested by turning the Audio Panel off.
In addition, the following functions are no longer available; NAV/ILS audio, speaker,
cockpit/cockpit-passengers intercom, aural warning alerts on headset, entertainment
inputs, and digital recording radio.
