Ground monitoring method and system for zero drift of an air route aircraft angle of attack sensor

Abstract

The application relates to a ground monitoring method and system for the zero drift of an angle of attack sensor of a line aircraft, comprising: collecting various flight parameters during the flight of the line aircraft; judging whether the aircraft is in a cruising steady flight stage according to the collected flight parameters; when it is determined that the aircraft is in the cruising steady flight stage, calculating the actual angle of attack of the aircraft according to a kinematic relationship and using relevant flight parameters; and judging whether to issue an angle of attack sensor zero drift warning according to whether the deviation between the actual angle of attack and the tabled angle of attack of the aircraft is greater than a deviation threshold. The judgment of the cruising steady flight stage is screening of a steady flight section.
