• PFD1 failure – MFD and PFD2 remain in normal mode.
• MFD failure – Both PFDs automatically switch to reversionary mode.
• PFD2 failure – MFD and PFD1 remain in normal mode.
Figure 1-11 Reversionary Mode
Reversionary mode can be activated manually by pressing the dedicated DISPLAY BACKUP button at the
bottom of the audio panel (see Figure 1-12 and refer to the Audio Panel section for further details). Pressing
this button again deactivates reversionary mode.
Figure 1-12 DISPLAY BACKUP Button
Pressing the DISPLAY 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 1-13). The system reverts to backup paths for the AHRS, ADC, Engine/Airframe Unit, and
Transponder, as required. The change to backup paths is completely automated for all LRUs and no pilot action
is required.
