Abstract
The present disclosure provides a method and a system for controlling operation of an engine of an aircraft. A first engine power limit associated with a thrust limit for a propeller coupled to the engine is obtained. The first engine power limit is compared to a second engine power limit associated with a mechanical limit for the engine and to a third engine power limit associated with a thermal limit for the engine. A maximum engine power limit is set at a lowest value of the first, second, and third engine power limits.
