Controller Aircraft
Senior MoD appointment delivering airworthy aircraft to the Services.
Controller Aircraft (CA), originally known as Controller of Aircraft, is a three-star senior appointment within the British Ministry of Defence. The role involves providing an airworthy aircraft to the Services, after which the Service grants a Release to Service (RTS) to formally introduce the aircraft into operational use. The distinction between a CA Release and an RTS typically relates to the Build Standard. While the post is most often filled by a Royal Air Force officer, several civil servants have occupied it during the 20th century. The holder also sits on the Air Force Board.
Before 1953, the duties now held by the Controller Aircraft were carried out by the Controller of Supplies (Air). In 1971, the position was transferred from the Ministry of Technology to the Procurement Executive of the Ministry of Defence.
