Embodiment Construction

[0020] As aircraft systems become more complex, aircraft data systems have evolved considerably. For example, the Aircraft Condition Monitoring System (ACMS) system of Airbus and the Aircraft Heath Monitor (AHM) system of Boeing Company.

[0021] Taking Airbus's ACMS system as an example, the ACMS system monitors the performance of several important components on the aircraft, including: engines, crew, airborne auxiliary power unit Airborne Auxiliary Power Unit (APU) and the cabin. The ACMS system also has the functions of monitoring important aircraft performance (Aircraft Performance Monitoring), data recording (Date Recording), special investigation and fault finding (Special Investigation&Trouble Shooting), etc.

[0022] The ACMS system monitors more than 13,000 flight data in real time. Moreover, when a certain trigger condition is met, ACMS can automatically generate a message containing specific data according to the real-time monitored data.

[0023] The ACMS system ...

Abstract

The invention relates to a plane landing quality detection method. The detection method comprises the following steps of: determining whether the vertical speed of a plane in landing exceeds a first predetermined value or whether the vertical acceleration of the plane exceeds a second predetermined value; acquiring landing data; responding to the state that the vertical speed of the plane in landing exceeds the first predetermined value or that the vertical acceleration of the plane exceeds the second predetermined value, and generating a landing message according to the acquired landing data; storing or transferring the landing message; and determining plane landing quality based on the landing data in the landing message.

Description

technical field [0001] The invention relates to a method for detecting the running state of an aircraft, in particular to a method for detecting the landing quality of an aircraft. Background technique [0002] The so-called "heavy landing (Heavy Landing)", or hard landing (Hard Landing), refers to the landing event in which the speed or acceleration in the vertical direction exceeds the limit value when the aircraft lands. Overrun, hard landing refers to the overrun when the landing weight of the aircraft is less than or equal to the maximum landing weight. Heavy / hard landings will cause strong shock and vibration to the structure of the aircraft, especially the aircraft components such as wings, landing gear and engines, which are subjected to heavy loads, and cause damage to the aircraft structure. Therefore, once a heavy / hard landing occurs, airlines must conduct strict safety checks on the aircraft to ensure aviation safety. [0003] Different airliners have different...
