Abstract:
The present disclosure provides methods and systems for controlling a propeller-driven aircraft powered by at least one gas turbine engine. A thrust change is obtained corresponding to a difference between an actual thrust and a desired thrust for an engine. When the thrust change is greater than a pre-determined threshold, a setting change to one or more control input(s) of the engine is determined. One or more commands are output to cause the setting change of the control input(s).
