The captain commands the upper actuator and the FO commands the lower actuator
|
|
|
What happens in the event of a jammed rudder PCU actuator
|
The rudder will be hydraulically locked in the current position. Aircraft control will be established through the ailerons and roll spoilers
|
|
|
Why would the flap/slats operate in 1/2 speed when the RAT is deployed
|
The slat/flaps are on AC BUS 1 and 2 and when the RAT is powered only the AC ESS BUS will receive power.
