Abstract
Herein provided are methods and systems for a method for controlling autothrottle of an engine. A digital power request is obtained from an autothrottle controller, the digital power request based on an autothrottle input to the autothrottle controller. A manual input mode for the engine is terminated, the manual input mode based on a second power request obtained from a manual input associated with the engine. An autothrottle mode for the engine is engaged to control the engine based on the digital power request.
Claims20
A method for controlling autothrottle of an engine for a turbopropeller-powered aircraft, comprising:
- obtaining, from an autothrottle controller, a digital power request, the digital power request based on an autothrottle input to the autothrottle controller;
- in response to obtaining the digital power request, terminating a manual input mode for the engine, the engine, when in the manual input mode, controlled based on a power request obtained from a manual input associated with the engine;
- engaging an autothrottle mode for controlling the engine based on the digital power request rather than on the power request obtained from the manual input;
- and
- adjusting a position of the manual input with the autothrottle controller based on the digital power request for controlling a transition of the engine out of the autothrottle mode.
A system for controlling autothrottle of an engine for a turbopropeller-powered aircraft, comprising:
- a processing unit configured to execute computer-readable program instructions;
- and
- a non-transitory computer-readable medium coupled to the processing unit and comprising the computer-readable program instructions for:
- obtaining, from an autothrottle controller, a digital power request, the digital power request based on an autothrottle input to the autothrottle controller;
- in response to obtaining the digital power request, terminating a manual input mode for the engine, the engine, when in the manual input mode, controlled based on a power request obtained from a manual input associated with the engine;
- engaging an autothrottle mode for controlling the engine based on the digital power request rather than on the power request obtained from the manual input;
- and
- adjusting a position of the manual input based on the digital power request for controlling a transition of the engine out of the autothrottle mode.
A method for controlling autothrottle of a powerplant of an aircraft, the powerplant comprising an engine and a propeller, the method comprising:
- obtaining, from an autothrottle controller, a digital thrust request, the digital thrust request based on an autothrottle input to the autothrottle controller;
- in response to obtaining the digital thrust request, terminating a manual input mode for the powerplant, the engine and the propeller, when in the manual input mode, controlled based on a power request obtained from a manual input associated with the engine;
- engaging an autothrottle mode for the powerplant for controlling the engine and the propeller based on the digital thrust request rather than on the power request obtained from the manual input;
- and
- adjusting a position of the manual input with the autothrottle controller based on the digital power request for performing a transition of the powerplant out of the autothrottle mode.
