Collision avoidance system and method

Abstract

Example implementations are directed to a method and system for collision avoidance for an aircraft traversing a flight path. The method and system described herein provides an architecture to address the full gamut of complexity that arises when dealing with possible conflicts during aircraft flight. The collision avoidance method and system disclosed herein first receives multiple streams of potential conflict information that not only considers direct obstacles on the flight path of the aircraft, but also considers contextual obstacles that are within a perimeter of the flight path. Once the possible objects are considered, a plurality of alternate flight paths are calculated and the alternate flight path with an acceptable miss distance with a possible obstacle (and minimized deviation from the original flight path) is selected and the aircraft traversing the flight path deviates from the original flight path to the alternate flight path to avoid the collision(s).
