A Risk Assessment-Based Method for Delineating UAV Control Areas in Airports

Abstract

The present invention provides a risk assessment-based method for demarcating UAV control areas at airports, comprising the following steps: establishing a UAV control area model based on air risk and ground risk, where the UAV control area is the core area of ​​air risk, air risk The combination of the buffer zone, the ground risk core area, and the ground risk buffer zone; designate the vertical boundary of the UAV control area around the airport; designate the air risk core area; designate the ground risk core area; The horizontal boundary of the core area and the established horizontal boundary of the air risk core area, calculate the horizontal extension distance of the buffer zone, respectively obtain the horizontal boundary of the ground risk buffer zone and the horizontal boundary of the air risk buffer zone, and combine the vertical boundary of the UAV control area to obtain the ground Risk buffers and air risk buffers. The design method of the present invention comprehensively considers air risks and ground risks, establishes a UAV control area designation model with UAVs as objects, and establishes two sets of track lateral distribution models in combination with the characteristics of each runway’s entry and departure procedures. The precise designation of drone control areas is of great significance to the airport's principles of balancing safety, efficiency, and economy.

Description

technical field [0001] The invention relates to the technical field of air traffic control, in particular to the air operation management of unmanned aerial vehicles. Background technique [0002] In recent years, the application of unmanned aerial vehicles (UA) in the public and commercial fields has grown rapidly, especially in very low altitude (VLL) airspace below 500 feet. Some typical examples include aerial photography, package delivery, surveillance, agriculture, disaster management, etc., bringing new modes to urban air mobility (UAM) and broadening the utilization of conventional airspace. However, with the increase of drone activities near the airport, the safety management of the airport will also face more severe challenges. [0003] To prevent the multiple risks posed by drones operating around airports, especially collisions between drones and flights, geofencing is beginning to be widely used to define protective boundaries around geographic points that unma...

Problems solved by technology

[0005] For example, the applicant’s previous research proposed that the patent application number is 201911306980.7, and the title of the invention is "A Method for Delineating the Control Area of ​​Airport UAVs Based on Collision Risk". Considering the complexity of the designation system for the control area of ​​different airports, the accuracy of the designation of the arrival and departure track is not enough, and it does not meet the more accurate and simplified management requirements of the existing airports.
