Abstract
A hazard warning system can be utilized in an aircraft. The hazard warning system can include a processing system for determining an icing condition and causing an indication of the icing condition to be provided to an engine control, such as a full authority digital engine control (FADEC). The engine can be operated in a mode in response to the indication. The mode can be a lower efficiency mode.
Claims20
An aircraft comprising:
- an engine;
- an engine controller;
- and
- an icing condition detector, the icing condition detector being configured to be in communication with the engine controller, determine a presence of an icing condition and provide an indication of the presence of the icing condition to the engine controller, wherein the engine controller is configured to operate the engine in a lower efficiency mode in response to the indication, wherein the engine is less susceptible to damage when operating in the lower efficiency mode than when operating in a higher efficiency mode in the presence of the icing condition.
1 more element
A method of controlling an engine using an electronic processor, the method comprising:
- detecting using a weather radar system an area associated with an icing condition;
- providing data associated with the icing condition to the electronic engine controller;
- and
- operating the engine using the electronic engine controller in a lower efficiency mode in response to the data indicating a presence of an icing condition.
1 more element
An aircraft weather system comprising:
- a processor configured to determine a presence of an icing condition in response to radar return data, the processor being configured to provide an icing threat signal if the icing condition is a threat to the aircraft, the icing threat signal being provided if a location of the icing condition is near the aircraft;
- and
- a communication circuit configured to provide the icing threat signal associated with the icing condition to an engine control.
