REVERSIONARy DISPLAy OPERATION
NOTE:
The system alerts the pilot when the LRUs are communicating using backup
paths. Refer to the Appendices for further information regarding system-specific alerts.
If either the PFD or MFD fails or is off-line, the system automatically shows a display Re-
versionary Mode. This mode combines a PFW display, an EIS display, and a Display Pane on
the operating display in a condensed format. If the system is unable to detect a failed PFD or
MFD, the pilot can manually activate display Reversionary Mode by pressing the red
DISPLAY
BACKUP
Button mounted between the PFD and MFD.
If the PFD fails or is off-line, GTC1 shows the Standby Flight Display, using attitude and air
data from the standby sensors. The Standby Flight Display includes an Airspeed Indicator,
Attitude Indicator, Altimeter and Altimeter Setting. Softkeys and knobs on GTC1 control the
Standby Flight Display; refer to the Flight Instruments Section for more information about
these controls. GTC2 provides the PFW or MFW Screens, and NAV/Com control modes on
the MFD operating in Reversionary Mode. Other conditions besides a PFD failure may cause
the Standby Flight Display to appear; refer to the AHRS Operation discussion for more infor-
mation on these conditions.
If the MFD fails or is off-line, GTC1 continues to operate as a Touchscreen Controller (i.e.,
no Standby Flight Display), and allows the selection of PFD Mode or NAV/Com Mode.
If both the PFD and MFD fail, GTC1 shows the Standby Flight Display. Since the PFD and
MFD are not available to control, the ‘PFW Home’ Screen and ‘MFW Home’ Screen on any
remaining Touchscreen Controller displays a large amber ‘X’ on the controller when PFD or
MFD control mode is selected.
TOUCHSCREEN CONTROLLER FAILURE
If GTC2 fails or is off-line, GTC1 continue to provide the same control modes as were previ-
ously available (PFW, MFW, NAV/COM). The Standby Flight Display is not available if GTC1
encounters a complete failure (for example, if GTC1 is not receiving any power.)
If both Touchscreen Controllers fail or are off-line, the PFD and MFD continue to operate in
Normal Mode, however, controls for the PFW, MFW, and NAV/COM tuning will be unavail-
able. Refer to the Audio and CNS Section for more information on NAV/COM failure modes.
ABNORMAL GPS CONDITIONS
The annunciations listed in the following table can appear on or near the HSI when abnor-
mal GPS conditions occur.
