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, comprising:
- obtaining, from an autothrottle controller, a digital power request, the digital power request based on an autothrottle input to the autothrottle controller;
- terminating a manual input mode for the engine, the manual input mode based on a second power request obtained from a manual input associated with the engine;
- and
- engaging an autothrottle mode for the engine for controlling the engine based on the digital power request.
A system for controlling autothrottle of an engine, comprising:
- a processing unit;
- and
- a non-transitory computer-readable medium coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for:
- obtaining, from an autothrottle controller, a digital power request, the digital power request based on an autothrottle input to the autothrottle controller;
- terminating a manual input mode for the engine, the manual input mode based on a second power request obtained from a manual input associated with the engine;
- and
- engaging an autothrottle mode for the engine for controlling the engine based on the digital power request.
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,
- terminating a manual input mode for the powerplant, the manual input mode based on a power request obtained from a manual input associated with the engine;
- and
- engaging an autothrottle mode for the powerplant for controlling the engine and the propeller based on the digital thrust request.
