METHODS AND SYSTEMS FOR MODIFYING FLIGHT PATH AROUND ZONE OF AVOIDANCE

Abstract:

Disclosed are methods, systems and non-transitory computer-readable medium for providing a flight path around a zone of avoidance located on a currently planned flight path of an aircraft. For instance, the method may include obtaining data of the zone of avoidance located on the currently planned flight path; determining a safe distance from the zone of avoidance based on a characteristic of the aircraft or a characteristic of the zone of avoidance; constructing a safety envelope outside of the zone of avoidance by defining the safety envelope based on the safe distance; constructing a plurality of alternate flight paths around the zone of avoidance such that each of the plurality of alternate flight paths avoids crossing into the zone of avoidance and avoids crossing in between the safety envelope and the zone of avoidance; and selecting an optimal flight path from among the plurality of alternate flight paths.
