When the selector is in the outboard position (OUTBD DU), the inboard display
unit is blanked. The outboard half of the outboard display unit shows the cropped
PFD. The inboard half displays EICAS if EICAS was previously shown on that
side of the flight deck. Otherwise, whichever display that was shown in place of
EICAS before the failure is shown.
Instrument Display Source Selection
The display system automatically reconfigures to compensate for most faults. The
Air Data/Attitude (AIR DATA/ATT) Source Selector is provided for the pilots to
use if certain faults are not corrected automatically.
The AIR DATA/ATT source selector controls the source of airspeed, altitude and
attitude information for the associated PFD and HUD. They have no effect on the
autoflight or navigation system.
If there is an undetected source failure, the non-normal (ALTN) position provides
the capability for manual selection of PFD and HUD sources.
