Figure 1-11 DISPLAY BACKUP Button
Pressing the D I S P L AY
BACKUP button activates/
deactivates reversionary
mode for both the on-side
PFD and the MFD.
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).
