SYSTEM OVERVIEW
Figure 1-10 Reversionary Mode (Manual)
Reversionary mode is entered based upon automatic fault monitoring and detection internal switching. This
mode can also be activated manually 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.
Figure 1-11 DISPLAY BACKUP Button
Pressi ng 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).
