The basic objective of air traffic control in military flying is, of course, the same as in any other flying; to enable all aircraft to fly safely throughout each flight with the maximum freedom to attain their purpose efficiently. In practice, this necessarily involves the imposition of conditions and restrictions, and it is one of the main aims in the development of air traffic services to increase both the safety and flexibility of aircraft operation with the minimum restrictions. In progressing this we fully recognise the needs of civil aviation and, contrary to some public misconceptions of civil/military conflict in air traffic control, a joint approach is made at all levels to resolve A.T.C. requirements.
