A method and system for providing training mode operation of a multiple engine aircraft simulates the failure of one engine and the simultaneous operation of at least one other engine in an elevated, emergency power condition. The engines (20, 22) are mechanically linked (24) and provide a single power output (26). A training power schedule (56a, 56b) is selected (60, 62) to limit the combined engine power output to a level equivalent to the combined output with one engine inoperative and another in an elevated, emergency power operating condition.

In an aircraft propulsion system having a plurality of engines linked mechanically for providing a single, combined mechanical power output, each engine being operable over a normal, sustainable range of power output and an elevated, emergency, short-term range of power output, a method for operating said system in a selective training mode wherein a failure of one of the engines and the simultaneous operation of at least one other of the plurality of engines within the emergency range of power output is simulated, comprising the steps of: monitoring the mechanical power output of each of the plurality of engines, comparing each engine power output with a simulation power output limit, the simulation limit determined responsive to an emergency combined power output limit produced by the plurality of engines during operation with one of the engines in a non-operative condition and at least one other engine operating in the emergency, elevated power range; controlling the output power of each engine responsive to an operator demand signal such that (a) each engine operates in the normal power output range, (b) the output power of each engine is substantially equivalent, and (c) the total combined power output of the linked plurality of engines does not exceed the emergency combined simulated output power limit.
