The flight crew can retract or extend the landing gear using the landing gear switch
on the center switch panel. Pilot commands from the landing gear switch are sent
through the PFD to both ACS’ which in turn command the three independent landing
gear actuators. Commands for gear position go directly to the actuator motor and
individual actuator status is sent back to the ACS. There are also several
independent position indications from several proximity sensors that are also sent to
the ACS for status display on the MFD.
Emergency extension of the landing gear is a direct mechanical release and does not
require ACS control to accomplish. There is a emergency landing gear handle
proximity switch that is monitored by the ACS that reports if the emergency gear
handle remains extended following an emergency gear extension.
