31 INDICATING/RECORDING SYSTEM PRESENTATION (1)
ELECTRONIC INSTRUMENT SYSTEM (continued)
EFIS CONTROL AND INDICATING
Flight parameters are displayed on the Primary Flight Display (PFD)
while navigation data is displayed on the Navigation Display (ND).
Outboard of the PFDs, there are control knobs to adjust the brightness
of the associated PFD and ND, and to turn the displays off.
Two EFIS control panels are used to select what is displayed on the
EFIS screens. The EFIS control panels are divided into two sections,
one section associated with the PFD and the other one with the ND.
Just below the ECAM screens, on the center pedestal, there is a
switching panel with, on the right, 2 rotary selectors to restore data
to the EFIS and ECAM displays in abnormal operation.
