Abstract
The present application discloses a method for detecting whether performance of an aircraft component is in a decline period, comprising: obtaining one or more detection parameters reflecting operation status of the aircraft component; comparing data of the one or more detection parameters with respective desired values; and determining whether the performance of the aircraft component is in the decline period based on a comparison result.

A computerized method for detecting whether performance of an aircraft component is in a decline period, comprising:
- obtaining one or more detection parameters reflecting operation status of the aircraft component and storing the detection parameters in a memory store;
- comparing data of the one or more detection parameters with respective predetermined values, at least one of said values provided as a reference slope of a change trend of at least one detection parameter, and wherein the step of comparing comprises calculating a slope of a change trend of the measured values of the one or more detection parameters in a period;
- using a processor to determine whether the performance of the aircraft component is in the decline period based on the comparison results;
- and
- performing a smooth processing on the measured values of at least one of the detection parameters,
- wherein the smooth processing adopts following formula:
- Xnew=C1Xsmooth+C2Xold
- wherein, Xold is the measured value, Xnew is a value after the smooth processing, Xsmooth is a value of adjacent points after the smooth processing or is an average value of several adjacent points, C1 and C2 are weighted values.
A computerized method for obtaining one or more detection parameters reflecting operation status of an aircraft component, comprising:
- obtaining multiple parameters related to operation status of the aircraft component and storing the detected parameters in a memory store;
- associating data of the multiple parameters with failure events of the aircraft component by monitoring a slope change in the parameters based on measured values, at least one of the parameters provided as a reference slope of a change trend of at least one detection parameter, and wherein the associating comprises calculating a slope of a change trend of the measured value of the one or more detection parameters in a period;
- using a processor to determine the detection parameters based on the associations between the multiple parameters and the failure events;
- and
- performing a smooth processing on the measured values of the one or more of the detection parameters,
- wherein, the smooth processing adopts following formula:
- Xnew=C1Xsmooth+C2Xold
- wherein, Xold is the measured value, Xnew is a value after the smooth processing, Xsmooth is a value of adjacent points after the smooth processing or is an average value of several adjacent points, C1 and C2 are the weight values.
