US Patent 10203700 Emergency autoland system

Autoland systems and processes for landing an aircraft without pilot intervention are described. In implementations, the autoland system includes a memory operable to store one or more modules and at least one processor coupled to the memory. The processor is operable to execute the one or more modules to identify a plurality of potential destinations for an aircraft; calculate a merit for each potential destination identified; select a destination based upon the merit; and create a route from a current position of the aircraft to an approach fix associated with the destination that accounts for the terrain characteristic(s) and/or obstacle characteristic(s). The processor can also cause the aircraft to traverse the route, determine a final approach segment associated with the route; identify terrain characteristic(s) and/or obstacle characteristic(s) associated with the final approach segment; and determine an adjusted final approach segment accounting for the terrain characteristic(s) and/or obstacle characteristic(s).
