Abstract
Systems and methods for detecting inclement weather in the vicinity of an aircraft engine are described herein. At least a first engine parameter and a second engine parameter are obtained, each engine parameter varies with changing weather conditions. An arithmetic value is determined as a function of at least the first engine parameter and the second engine parameter. The arithmetic value varies with changing weather conditions. A rate of change of the arithmetic value is determined. Inclement weather is detected when the rate of change exceeds a threshold.
Claims28
A method for detecting inclement weather in the vicinity of an aircraft engine, the method comprising:
- obtaining at least a first engine parameter and a second engine parameter, each engine parameter varying with changing weather conditions;
- determining an arithmetic value as a function of at least the first engine parameter and the second engine parameter, the arithmetic value varying with changing weather conditions;
- determining a rate of change of the arithmetic value based on a derivative of the arithmetic value;
- and
- detecting inclement weather when the rate of change exceeds a threshold.
The method of clam 1, wherein the threshold depends on at least the first engine parameter and the second engine parameter.
A system for detecting inclement weather in the vicinity of an aircraft engine, the system comprising:
- at least one processing unit;
- and
- a non-transitory computer-readable memory having stored thereon program instructions executable by the at least one processing unit for:
- obtaining at least a first engine parameter and a second engine parameter, each engine parameter varying with changing weather conditions;
- determining an arithmetic value as a function of at least the first engine parameter and the second engine parameter, the arithmetic value varying with changing weather conditions;
- determining a rate of change of the arithmetic value based on a derivative of the arithmetic value;
- and
- detecting inclement weather when the rate of change exceeds a threshold.
