A Design Method of UAV Flight Protection Area Based on the Statistical Analysis of Flight Path Deviation

Abstract

According to the design specification of International Civil Aviation Organization(ICAO) document No. 8168, by referring to the flight record data of UAV and using the statistical and analysis method of flight line deviation limit data, the limit data is obtained, and according to the definition of collision probability model in flight programming specification, the design method of flight protection area for UAV is obtained based on flight path deviation limit data. A simulation experiment was established based on the computational simulation. The calculation results showed that: The design of UAV flight protection area is mainly determined by navigation accuracy, positioning mode, flight link and other factors, and the weight is different. By improving the accuracy and changing the flight link, the scope of UAV flight protection area can be effectively reduced. In the future, the joint operation of manned aircraft and UAV in the hollow and low-Altitude airspace provides the basis for airspace planning, which further ensures flight safety and improves operational efficiency.
