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; andflying the aircraft to the landing site using the description of the state of the aircraft along the route of the aircraft over time. 2. The method of claim 1 further comprising: continuously updating a group of routes to the group of landing sites for the aircraft, wherein the route to the landing site is within the group of routes to the group of landing sites. 3. The method of claim 2, wherein the updating step comprises: continuously updating the group of routes to the group of landing sites for the aircraft based on a range of the aircraft, wherein the route to the landing site is within the group of routes to the group of landing sites. 4. The method of claim 1, wherein the route takes into account a group of obstacles along the route from the current location of the aircraft to the landing site. 5. The method of claim 1, further comprising communicating comprising aircraft intent description language, wherein the aircraft is a first aircraft and wherein the selecting and communicating steps are performed in a location selected from one of; the first aircraft, a ground station, an air traffic control station, and a second aircraft. 6. The method of claim 1, wherein the description comprises instructions that describe an aerodynamic configuration of the aircraft and a motion of the aircraft. 7. The method of claim 6, wherein the instructions follow rules for describing the aerodynamic configuration of the aircraft and the motion of the aircraft, based upon a performance model, for the aircraft, continually generated from actual performance data of the aircraft. 8. The method of claim 1, wherein the aircraft is a first aircraft, the platform is a second aircraft, and the second aircraft is configured to use the description to perform collision avoidance. 9.
