PCL Operation
Power Control Lever operation aft of the idle detent is prohibited:
▪ When engine is not running.
▪ During flight. Such operation may lead to loss of airplane control and total
power loss.
▪ When engine is controlled by the Manual Override System. Such operation may lead to loss of airplane control or may result in an engine/propeller overspeed condition and consequent loss of engine power.
