System and method for processing digital air data

Abstract

The invention provides novel system and method for processing digital air data, wherein GPS data and digital air data, which are acquired by a plane, are transmitted to a ground station in real time; and the ground station is used for carrying out differential treatment on the received GPS data by using the obtained accurate plane GPS data and calibrating part related to the GPS data in the digital air data according to a differential treatment result. According to at least one embodiment of the invention, the accuracy of the GPS data and the digital air data is effectively monitored in real time, thus the error of the digital air data is known as soon as possible so as to make the regulation and avoid the accidents.

Description

technical field [0001] The invention relates to digital flight data, in particular to a system and method for collecting and processing digital flight data. Background technique [0002] During the flight of the aircraft, the digital flight data collectors onboard will collect various digital flight data related to the performance and status of the aircraft, and store them in the digital flight data recorder, that is, people The so-called black box. After the flight, the data in the black box can be exported on the ground for aircraft debugging, maintenance, upgrades and even pilot evaluation. The content of the above-mentioned digital flight data is very detailed, typically including: aircraft flight altitude, speed, fuel quantity, landing gear status and so on. [0003] In order to allow pilots to better understand the state of the aircraft and respond to emergency situations, these digital flight data are also provided to pilots during the flight. [0004] Today's airc...

Problems solved by technology

[0005] Although pilots can refer to the data collected by various types of data collectors, thus improving the credibility of the data to a certain extent through equipment redundancy, however, whether digital flight data collectors or airborne GPS data collection However, the absolute accuracy of data collection cannot be guaranteed, and there are still hidden dangers that cannot be ignored for the personnel on board and the aircraft.

In addition, the inaccurate digital flight data is not conducive to subsequent data analysis
