SELF-SEPARATION ALGORITHM USING SPEED CONTROL FOR WIDTH-LIMITED HIGH DENSITY AIR CORRIDOR

摘要

Algorithms for self-separation of aircraftoperating in a high density air corridor arediscussed. An air corridor is a tube or bandshapedpiece of airspace that connects highdemandcity areas etc. Aircraft in the aircorridor all fly in the same direction, and onlyaircraft capable of self-separation may operatein the air corridor. An appropriate selfseparationalgorithm is indispensable torealizing high traffic throughput whilemaintaining safety. In this paper, an algorithmfor self-separation of aircraft in a width-limitedband-shaped piece of airspace has beendeveloped. The algorithm refers to the relativeposition and speed of aircraft for conflictavoidance based on the assumption that allaircraft intend to fly along the air corridor. It isdemonstrated that all the aircraft are able toself-separate without conflict in the widthlimitedair corridor. It is also demonstrated thatself-separation using current state informationresults in a deadlock in the narrow air corridor.As the corridor width increases, aircraft utilizemore space to overtake and aircraft are able tofly at their optimum speed. Additionally, it isindicated that the installation of sub-route andutilization of optimum speed informationprevent a deadlock even though the corridorwidth is narrow.
