Method and apparatus for controlling an aircraft.

摘要

Each engine (32) of a multi-engine aircraft is monitored to determine if it has become inoperative during a critical flight mode such as takeoff or landing. If so, the propeller (66) of the inoperative engine is feathered and the remaining engine or engines is uptrimmed. A "state machine" (30) indicative of the various states of the aircraft is established and the present state of the aircraft is stored in a non-volatile memory (74); if an electrical power interruption occurs during a critical flight mode the identity of the present operating state may be quickly recalled for immediate refeathering of an inoperative engine and reuptrimming of the remaining engine or engines.
