A system and method are provided for controlling the power setting of an aircraft engine when the current height-above-terrain (HAT) value Hc is less then a predetermined minimum H(min). The system includes a ground proximity unit (GPU) for measuring 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 and the one or more sensors and the engine, for controlling operation of the engine in response to Hc, H(min) and the engine operating values. When the one or more sensors detects an out-of-range operating condition normally curable by reducing the engine power setting, the ECU is prevented from automatically reducing the power setting of the engine if Hc<H(min). No pilot action is required.
