PRIMARY DISPLAY SYSTEM -AUTOMATIC DISPLAY SWITCHING
General
The PFD display on the outboard DUs and the EICAS display on the upper center DU automatically move to alternate locations when a DU failure occurs.
When only one DU shows the EICAS display, EICAS is in the limited mode. In the limited mode, only these three switches on the DSP have a function:
*
ENG switch
*
AIR switch
*
FUEL switch.
Outboard DU Failures
The PFD display automatically moves to the onside inboard location when a detected failure of the outboard DU occurs.
After the PFD display moves automatically, the inboard display selector on the display switching panel has no effect on the inboard DU.
Upper Center DU failures
The EICAS display automatically moves to the lower center DU when a detected failure of the center upper DU occurs. The lower DU then shows the compacted engine display.
The ENG switch on the DSP causes the display to change between EICAS display and compacted engine display.
The AIR switch controls the ECS data block.
The FUEL switch controls the fuel quantity and fuel imbalance display.

PRIMARY DISPLAY SYSTEM -PFD MANUAL SWITCHING
General
The PFD position of the inboard display selector on the display switching panel lets the operator move the PFD format to the inboard DU.
The outboard DU blanks when the selector is in the PFD position.
Return the inboard display selector to NORM (ND or MFD) to cause the PFD to show on the outboard DU and to cause the ND format to show on the inboard DU.

PRIMARY DISPLAY SYSTEM -MANUAL EICAS SWITCHING
General
The EICAS position of the inboard display selector on the display switching panel lets the operator move the EICAS display format to the inboard DU.
Both inboard DUs can show the EICAS display format at the same time. Both displays will be identical. One DU cannot show EICAS display and the other show compacted engine.
The upper center DU blanks when the inboard display selector is in the EICAS position.
Return the inboard display selector to NORM (ND or MFD) to cause the engine EICAS display to show on the upper center DU and to cause the ND format to show on the inboard DU.

PRIMARY DISPLAY SYSTEM -MULTIPLE DU FAILURES
General
The display select panel (DSP) switches and the inboard display selectors on the display switching panel provide system redundancy when multiple DU failures occur.
The EICAS position of the inboard display selector causes the EICAS display format to show on an inboard DU.
The L INBD or R INBD switch on the DSP causes other EICAS formats to show on an inboard DU. The inboard display selector must be in the MFD position before the DSP L INBD or R INBD switch will have effect.
The L INBD or R INBD switch also has no effect if an outboard DU fails and the PFD automatically switches to an inboard DU.
