Abstract
System and method for detecting an uncommanded high thrust (UHT) event in an aircraft. The method comprises enabling a UHT function associated with an engine when an enabling condition has been met. When the UHT function is enabled, the UHT event is detected when a power lever of the aircraft is at a given position, a parameter indicative of engine speed or power is above a first threshold, and a rate of change of the engine speed is above a second threshold. In response to detecting the UHT event, an alert is output to trigger accommodations to the UHT event for the engine.
