ABSTRACT:
A pilot indicator is provided for an aircraft provided with at least one gas turbine engine. The indicator includes a set of sensors delivering information relating to different monitoring parameters of the engine, namely: the speed of rotation Ng of the gas generator, the temperature T4of the gas at the inlet of the free turbine, and the torque Cm. The indicator is also provided with a processor for processing information from the sensors, and a display provided with a display screen. In addition, the processor determines an estimated value of a limiting parameter, where the limiting parameter is that one of the monitoring parameters that is closest to its limit.
