Provided herein is a method for detecting landing quality of an aircraft. Method steps include using an aircraft data system to determine whether a vertical speed rate is greater than a first preset value when the aircraft lands; determine whether a vertical acceleration is greater than a second preset value if the vertical speed rate is not greater than the first preset value when the aircraft lands; collect landing data; generate a landing message based on the collected landing data; store or transmit the landing message; and determine the landing quality based on the landing data in the landing message.

Method for detecting the landing quality of an aircraft

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.
