Problems solved by technology

[0004] At present, in order to be able to find out whether the aircraft has landed over-limit in time, it is necessary to collect the landing data of the aircraft to analyze and evaluate the performance of the aircraft. Airlines often use the method of decoding flight data. However, due to the The timing process is relatively complicated, and the sampling accuracy and calculation method of flight data decoding cannot meet the requirements of Airbus. To avoid judgment errors, the original data can only be sent to Airbus for analysis. The cost is high, and the waiting time longer, and affect the normal operation of the aircraft

Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific embodiments. Embodiments of the present invention are not limited to the following examples, and various changes made without departing from the gist of the present invention fall within the scope of protection of the present invention.

[0017] Example. Aircraft landing performance data collection method, the aircraft activates the trigger LAND11 during approach, and the trigger LAND11 detects whether the left main landing gear shock strut and / or the right main landing gear shock strut of the aircraft changes from an extended state to a compressed state Thereby it is judged whether the aircraft has been grounded, if it is grounded, the trigger LAND22 or trigger LAND22B, trigger LAND33 and trigger LAND44 are activated, and the trigger LAND22 or trigger LAND22B is used to judge whether the vertical velocity exceeds the vertical velocity threshold value when the aircraft is grounded. If it ...

Abstract

The present invention relates to a method for detecting landing quality of an aircraft, comprising: determining whether a vertical speed rate is greater than a first preset value or a vertical acceleration is greater than a second value when the aircraft landing; collecting landing data; generating a landing message based on collected landing data in response to that the vertical speed rate is greater than the first preset value or the vertical acceleration is greater than the second value when the aircraft landing; storing or transmitting the landing message; and determining the landing quality of the aircraft based on the landing data in the landing message.

Description

technical field [0001] The invention relates to a method for collecting aircraft performance data, in particular to a method for collecting aircraft landing performance data. Background technique [0002] The aircraft manufacturer AIRBUS stipulates that the main body of responsibility for reporting hard or heavy landing incidents is the flight personnel, but the subjective feelings and experiences of the reporters are different, and they are also affected by some external factors, such as airline management regulations, flight quality, etc. Regulations of monitoring agencies, etc., lead to uncertainty about hard or heavy landing events reported by flight personnel. Through the processing of a large number of hard or heavy landing events, we found that the final result of most of the event processing was normal, but the entire processing process resulted in a large number of maintenance work and aircraft operation interruption. [0003] In the flight quality monitoring depar...
