3.6 Reversionary Mode
Reversionary mode allows for display of information related to safe flight in the event of a display
communication or hardware failure. For software version 0985.04 and later, the pilot’s PFD
automatically goes into reversionary mode when communication to the MFD is lost. Manual
reversionary mode allows the operator to force the pilot or copilot’s PFD into reversionary mode by
pressing the large red button labeled ‘DISPLAY BACKUP’ on the respective GMA 1347D audio panel.
NOTE
When the ‘DISPLAY BACKUP’ button is pushed to exit reversionary mode, there is a 5-
second debounce (or the GDU waits for 5 consecutive seconds) and then returns to
normal mode if no other input is received. If the ‘DISPLAY BACKUP’ button is pushed
again during this 5-second interval, the timer will repeat the count.
