DETERMINING EMERGENCY LANDING SITES FOR AIRCRAFT

A routing tool is disclosed. The routing tool is configured to determine a landing site for an aircraft by receiving flight data. The routing tool identifies at least one landing site proximate to a flight path and generates a spanning tree between the landing site and the flight path. According to some embodiments, the landing sites are determined in real-time during flight. Additionally, the landing sites may be determined at the aircraft or at a remote system or device in communication with the aircraft. In some embodiments, the routing tool generates one or more spanning trees before flight. The spanning trees may be based upon a flight plan, and may be stored in a data storage device. Methods and computer readable media are also disclosed.
