ABNORMAL OPERATION
REVERSIONARY MODE
If the system detects a failure in the MFD, reversionary mode is entered
automatically. Reversionary mode must be entered manually in the case of
PFD1 or PFD2 failure. In reversionary mode, critical flight instrumentation is
combined with engine instrumentation on the remaining display.
Manual activation of reversionary display mode is accomplished by pressing the
DISPLAY BACKUP Button on the appropriate audio panel.
• 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.
NOTE: The Cessna CitationJet Model 525 Airplane Flight Manual (AFM) always
takes precedence over the information found in this section.
ABNORMAL COM OPERATION
When a COM tuning failure is detected by the system, the emergency frequency
(121.500 MHz) is automatically loaded into the active frequency field of the COM
radio for which the tuning failure was detected. In the event of a failure of both PFDs,
the emergency frequency (121.500 MHz) automatically becomes the active frequency
on both COM radios.
AUDIO PANEL FAIL-SAFE OPERATION
If there is a failure of both Audio Panels, a fail-safe circuit connects the pilot’s headset
and microphone directly to the COM1 transceiver and the copilot’s headset directly to
the COM2 transceiver. Audio is not available on the speakers. If there is a failure of one
Audio Panel, that side only has access to their respective on-side fail-safe COM.
NOTE: Audio is not available on the speakers in case of an Audio Panel and
its cross-side GIA unit simultaneous failure.
If there is a failure of one Audio Panel, the remaining Audio Panel does not have
access to the other side’s COM or NAV. For example, if the pilot side Audio Panel
