1. A method for managing a landing site for an aircraft, the method comprising:
- selecting, using a navigation tool, the landing site from a group of landing sites;
determining, using a routing tool, a touchdown point on the landing site;
growing, using the routing tool, a spanning tree comprising a minimum cost path up from the touchdown point to an origin point in the air;
computing, using the routing tool, a route from a current location of the aircraft to the origin point, the route being four-dimensional;
communicating, to a platform, a description of a state of the aircraft along the route of the aircraft over time to the landing site; and
flying the aircraft to the landing site using the description of the state of the aircraft along the route of the aircraft over time.

Abstract
A method and apparatus for managing a landing site for an aircraft is presented. The landing site is selected from a group of landing sites. A description is communicated to a platform about a state of the aircraft along a route of the aircraft over time to the landing site. The aircraft is flown to the landing site using the description of the state of the aircraft along the route of the aircraft over time.

11. An apparatus comprising:
-
a navigation tool configured to select a landing site from a group of landing sites and communicate to a platform a description of a state of an aircraft along a route of the aircraft over time to the landing site; and a routing tool configured to; determine a touchdown point on the landing site; grow a spanning tree comprising a minimum cost path up from the touchdown point to an origin point in the air; and compute a four-dimensional route from a current location of the aircraft to the origin point. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method for selecting a landing site for an aircraft in flight, the method comprising;
-
monitoring a current state of the aircraft and an issue at a destination; determining when at least one of;
the current state of the aircraft, and the issue at the destination, make landing at the destination undesirable;selecting, using a navigation tool, the landing site from a group of landing sites, based upon a group of factors comprising;
terrain data, airspace data, weather data, vegetation data, transportation infrastructure data, populated areas data, obstructions data, and utilities data;determining, using a routing tool, a touchdown point on the landing site; growing, using the routing tool, a spanning tree comprising a minimum cost path up from the touchdown point to an origin point in the air, such that cost comprises a function of at least one of;
time, energy, and fuel;computing, using the routing tool, a four-dimensional route from a current location of the aircraft to the origin point, based upon the group of factors; and communicating to another aircraft and at least one of;
an Air Traffic Control center, an Airborne Operations Center, and an Air Route Traffic Control Center, a description of a state of the aircraft along the route of the aircraft over time to the landing site.
