extended is prohibited.
The resultant advantage of the flight power shutoff provision is the ability to
bypass a malfunctioning actuator (such as would be the need in the
unlikely event of an actuator jam) and manually fly the aircraft. Although
control column effort and response time to inputs are increased while in
manual reversion, the aircraft remains capable of positive and harmonious
control.
