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.

1. A computer-implemented method for generating safe ingress flight paths to an identified landing site for an aircraft, the method comprising: generating, by a processing device, a spanning tree for the identified landing site by producing a plurality of possible approach paths by starting at a touchdown point on the identified landing site and building each of the plurality of possible approach paths from the touchdown point outward while minimizing altitude changes while moving away from the touchdown point,identifying obstructions proximate the identified landing site, andeliminating any obstructed possible approach paths of the plurality of possible approach paths that conflict with the obstructions to produce a plurality of allowed approach paths to the touchdown point;storing, in a data storage device, the spanning tree including the allowed approach paths;providing information from the spanning tree in the data storage device to an in-flight display for use by aircraft personnel; and providing a countdown timer with each of the plurality of allowed approach paths indicating a time in which the allowed approach path remains available as an option for the identified landing site. 2. The method of claim 1, further comprising: receiving, by the processing device, flight data corresponding to a flight path, wherein receiving the flight data comprises receiving the flight data at a routing tool associated with the aircraft during planning of a flight. 3. The method of claim 2, wherein receiving the flight data comprises receiving the flight data at a routing tool associated with the aircraft during a flight. 4. The method of claim 2, wherein receiving the flight data comprises receiving the flight data at an off-board routing tool associated with an air traffic control system before a flight is commenced. 5. The method of claim 4, further comprising: detecting, by the processing device, an emergency condition during a flight of the aircraft; andin response to detecting the emergency, transmitting data to the air traffic control system indicating occurrence of the emergency; andreceiving the spanning tree from the air traffic control system. 6.
