Aircraft performance detection method

Abstract

The invention discloses an aircraft performance detection method, which comprises the following steps that: the aircraft auxiliary power unit (APU) operation state aircraft communications addressing and reporting system (ACARS) messages and the ACARS oxygen messages formed by an onboard oxygen system operation state after once aircraft flight are obtained, and the aircraft APU operation state ACARS messages and the ACARS oxygen messages are decoded to obtain aircraft performance data to be processed, so the aircraft APU performance and the onboard oxygen performance are judged, the aircraft performance is normal when the aircraft APU performance and the onboard oxygen performance are both normal, and the aircraft performance is abnormal when either the aircraft APU performance or the onboard oxygen performance is abnormal or both the aircraft APU performance and the onboard oxygen performance are abnormal. The aircraft performance detection method has the advantages that the operation cost of an airline company can be reduced, in addition, the operation safety of aircrafts can be improved, the fault can be eliminated in time, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a detection method, in particular to an aircraft performance detection method. Background technique [0002] Aircraft performance testing generally includes aircraft APU performance testing and airborne oxygen performance testing. [0003] APU: AIRBORNE AUXILIARY POWER (airborne auxiliary power unit), this device mainly provides electricity and compressed air for the aircraft when it is on the ground, and a small amount of APU can also provide additional thrust to the aircraft. Before the aircraft takes off on the ground, the main engine is powered by the APU, so that it does not need to rely on ground electricity and air source vehicles to start the aircraft. When on the ground, the APU provides electricity and compressed air to ensure the lighting and air conditioning in the cabin and cockpit. When the aircraft takes off, all the engine power is used for ground acceleration and climb, which improves the take-off performance....

Problems solved by technology

However, in the routine detection of airborne oxygen, the pressure of the airborne oxygen system is usually recorded manually, and the oxygen cylinder is replaced according to the hard time limit or when the pressure of the airborne oxygen system is lower than the set value, the aircraft system sends out an alarm. Alarm to replace the oxygen cylinder, which increases the operating cost of the airline. If there is a small leak in the airborne oxygen system, the failure cannot be solved in time, resulting in the operational safety of the aircraft cannot be guaranteed
