Controls and Indicators
General
The Flight Control Panel (FCP) provides the majority of controls for flight director
and autopilot operation. The Reversionary/Inhibit Panel allows selection between
AFCS 1 and 2. Both the pilot’s and copilot’s control wheel incorporates pushbuttons
for autopilot disconnect and flight director synchronization.
The PFD Flight Mode Annunciator (FMA) provides an indication of autopilot and
flight director status. The EICAS Primary and Status pages provide the system
warning, caution and status messages, respectively.
