SECTION 2 – PFD

2.9 DISPLAY BACKUP

The PFD is designed to enter a reversionary (backup)
mode should one of the displays become unavailable in
flight, based on automatic fault monitoring and detection
and internal switching. Reversionary mode can also be
set manually by pressing the DISPLAY BACKUP button
at the bottom of the audio panel (refer to the Audio Panel
Pilot' s Guide). In reversionary mode, the displays are re-
configured to present the PFD symbology together with
the engine parameters.

Transition for the pilot is straightforward since PFD
parameters are presented in the same format as that prior
to the re-configuration. In the event of a complete display
failure, the pilot loses one NAV, COM, and GPS depending
on which display fails. The list below shows what is lost:
• PFD Fails: NAV1, COM1, and GPS1 are lost.
• MFD Fails: NAV2, COM2, and GPS2 are lost.
NOTE: Refer to the System Overview in the
G1000 Pilot's Guide for a detailed description of
Reversionary Mode.
