Problems solved by technology

In recent years, there have been frequent takeoff incidents, but it is difficult for the air carrier to know the news in the first place. If the crew does not report it, the airline acknowledgment may not be aware of the incident, which will cause hidden dangers for the safe operation of the flight.

Embodiment 1

[0051] A kind of aircraft suspension taking off identification method based on real-time ADS-B data, its method comprises as follows:

[0052] A. Collect flight dynamics, ACARS message data, and ADS-B data in real time, comprehensively identify aircraft launch and take-off time windows based on flight dynamics, ACARS message data, and ADS-B data, and select departing aircraft operating at the airport; The ADS-B data collection of the present invention comes from ADS-B equipment, and ADS-B data comprises flight number, longitude, latitude, height; Described airport runway data comprises runway width, length, runway number, airport ICAO code, longitude, latitude. The aircraft in this embodiment is preferably a civil aviation aircraft.

[0053] B, collect airport runway data, extract airport runway edge latitude and longitude data and obtain a closed airport runway contour curve (such as Figure 2 to Figure 8 As shown, the contour curve of the airport runway is a closed rectangu...

Embodiment 2

[0072] A kind of aircraft suspension take-off recognition method based on real-time ADS-B data, present embodiment is applied to various types of airports (comprising standardized civil aviation airports, standardized military airports or small airports) with relatively good ADS-B signal coverage on the airport scene, Its methods include the following:

[0073] A. Collect flight dynamics, ACARS message data, and ADS-B data in real time, comprehensively identify aircraft launch and take-off time windows based on flight dynamics, ACARS message data, and ADS-B data, and select departing aircraft operating at the airport; The aircraft in this embodiment is preferably a civil aviation aircraft.

[0074] B. Collect airport runway data and form a runway latitude and longitude database, extract the airport runway edge latitude and longitude data and obtain a closed airport runway profile curve (such as Figure 2 to Figure 8 As shown, the contour curve of the airport runway is a close...

Abstract

The invention discloses a method and system for identifying aborted takeoff of an aircraft based on real-time ADS-B data. The alarm output module, the aircraft takeoff acquisition module are connected with the aircraft trajectory data processing module, the runway data acquisition module, and the aircraft trajectory data processing module are respectively connected with the runway profile curve generation module, and the aircraft trajectory data processing module and the runway profile curve generation module are respectively connected with the aborted takeoff module Determine the processing module connection. The present invention calculates and analyzes the number of intersection points between the aircraft surface operation trajectory and the airport runway contour curve, and combines the speed change data in the aircraft runway and the aircraft trajectory direction to realize the real-time alarm of aircraft surface operation suspension and take-off abnormality, and can effectively solve the delay report of aborted takeoff , Underreporting, and underreporting.

Description

technical field [0001] The invention relates to the field of aircraft take-off safety, in particular to a method and system for identifying aircraft aborted take-off based on real-time ADS-B data. Background technique [0002] The Civil Aviation Administration of China, airlines, aircraft manufacturers, and other organizations have joined forces to improve takeoff safety and have begun an in-depth study of aborted takeoffs. Take-off is a flight stage that lasts very short but has a high accident rate. According to the statistics of the International Civil Aviation Organization, take-off accidents account for about 25% of the total flight accidents. There are reports of take-off accidents at home and abroad from time to time. Takeoff accidents accounted for about half. On the morning of November 13, 2018, a Delta Air Lines A350 passenger plane at Shanghai Pudong Airport, flight number DL582, planned to fly from Shanghai to Detroit. When taking off and rolling on the R34L run...
