Claim:
1. A system for controlling the power setting of an aircraft engine, comprising: a ground proximity unit (GPU) for measuring current aircraft height-above-terrain (HAT) values Hc; one or more sensors coupled to the engine for detecting an out-of-range operating condition of the engine; an engine control unit (ECU) coupled to the GPU, the one or more sensors and the engine for controlling operation of the engine in response to Hc and engine operating values determined by the one or more sensors; and wherein, when the one or more sensors detects an out-of-range operating condition of the engine, which out-of-range operating condition of the engine is normally curable by reducing the engine power setting in order to prevent harm to the engine, the ECU, does not automatically reduce the power setting of the engine if Hc<H(min) wherein H(min) is a minimum cruising HAT value for the aircraft.
