Abstract: A computer implement method of aircraft selection involves providing parameters and a set of logic rules reflecting laws, regulations and policies relating to safe operation of an aircraft, along with a database of aircraft relating to a fleet of aircraft of the same type. There is input into a computer processor a request for an aircraft to fulfil a mission at a time a pilot declares readiness for an aircraft. The computer processor makes a selection from the database of aircraft a first subset of aircraft that are available and capable of safely performing the mission.
