Controller Aircraft

Controller Aircraft (CA), originally Controller of Aircraft, is a senior (3 star) British Ministry of Defence appointment who is responsible for delivering an airworthy aircraft to the Services, whereupon the Service issues a Release to Service (RTS), releasing the aircraft into service. The difference between CA Release and RTS is normally one of Build Standard. Although usually held by a Royal Air Force officer, several civil servants have held the post in the 20th century. The incumbent is a member of the Air Force Board.

History
Prior to 1953, the equivalent responsibilities were held by Controller of Supplies (Air). In 1971 the post was moved from the Ministry of Technology to the Ministry of Defence's Procurement Executive.
