Reversionary Mode - Garmin Socata TBM850 Pilot's Manual

SYSTEM OVERVIEW

REVERSIONARY MODE

The G1000 system alerts the pilot when backup paths are utilized by the LRUs. Refer to the Appendices
NOTE:
for further information regarding system-specific alerts.
Reversionary mode is a mode of operation in which all important flight information is presented identically
on at least one of the remaining displays (see Figure 1-10). Transition to reversionary mode should be
straightforward for the pilot, for flight parameters are presented in the same format as in normal mode.
Reversionary mode is activated by pressing the dedicated DISPLAY BACKUP button at the bottom of the
audio panel (see Figure 1-11 and refer to the Audio Panel section for further details). Pressing this button again
deactivates reversionary mode.
Each display can be configured to operate in reversionary mode, as follows:
• PFD1 – By pressing the DISPLAY BACKUP button on the left audio panel.
• MFD – By pressing the DISPLAY BACKUP button on the left or the right audio panel.
• PFD2 – By pressing the DISPLAY BACKUP button on the right audio panel.
Should the connection between a PFD and the on-side GIA 63W become inoperative, the on-side GIA 63W
can no longer communicate with the remaining PFD (refer to Figure 1-1). As a result, the NAV and COM
functions provided to the failed PFD by the on-side GIA 63W are flagged as invalid (red "x") on the remaining
PFD (see Figure 1-12).
