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).

A system for controlling the thrust of the engines of an aircraft comprises a processing unit configured to receive an aircraft speed setting, to determine a control setting for at least one engine of the aircraft as a function of the speed setting and to transmit a setting to a controller of the at least one engine of the aircraft as a function of the control setting. The processing unit is further configured to receive a current turbulence level measurement information item and to add an additional speed setting, as a function of the turbulence level, to the speed setting.

There are described methods and systems for controlling an aircraft. The system comprises a power plant controller configured for controlling operation of an engine and a propeller coupled to the engine, a power throttle having at least one throttle lever to regulate output power of the engine and thrust produced by the propeller, and an autothrottle controller operatively connected to the power plant controller and to the power throttle and configured to modulate engine power without pilot input by causing a change to at least one setting of the power throttle.

There are described methods and systems for providing an autothrottle mode in a propeller-driven aircraft. A thrust change is obtained corresponding to a difference between an actual thrust and a desired thrust for an engine. When 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 is output to cause the setting change of the control input(s).
