Close-range parallel runway collision risk and safety interval calculation system and method

Abstract

The invention discloses a close-range parallel runway collision risk and safety interval calculation system and a method. The system is configured to have four big parts: a software interface, basic information, function calculation and a database. On the basis of running and operation of a system program, and through an establishment of a close-range parallel runway collision risk model, collision risk probabilities and safety intervals of two airplanes in lateral, longitudinal and vertical directions can be calculated respectively, and collision risks and safety intervals of a close-range parallel runway running aircraft in different running modes can be calculated rapidly in real time. According to the system, on the premise that safety is guaranteed, an interval standard is appropriately reduced, the spatial domain utilization rate is substantially improved, the airport capacity is increased, an assistance is provided for solving the problem of increasingly serious flight delays. Airline company running efficiency is improved, runway land is reduced, and the problem that a new built runway has an impact on environment is solved well.

Description

technical field [0001] The invention relates to civil aviation safety technology, in particular to a system and method for calculating the collision risk and safety interval of short-distance parallel runways. Background technique [0002] Air transport has always been one of the main modes of long-distance transport at home and abroad. With the rapid development of the air transportation industry and the rapid growth of air traffic flow, problems such as air traffic congestion, scarcity of airspace capacity, and flight delays have gradually become prominent. The capacity of airports, especially busy airports, is close to saturation, which becomes the capacity bottleneck of the airspace system. To improve this situation, building more runways has become a common way to increase operating capacity. Because many airports have less available land resources and the expansion of the airport is more restrictive, so the construction of short-distance parallel runways has become t...

AI Technical Summary

Problems solved by technology

The current safety separation standards for parallel runway operations are based on the 9643 document issued by the International Civil Aviation Organization, but it is becoming more and more difficult to meet the increasing traffic flow

Due to the lack of research on the collision risk of short-distance parallel runway operation, the safety separation standard used during short-distance parallel runway operation cannot be effectively reduced, and the full effectiveness of short-distance parallel runway has not been fully utilized
