The Assistant Chief of the Air Staff (ACAS) is a senior appointment in the Royal Air Force. The current ACAS is Air Vice-Marshal Suraya Marshall.
The post was originally established circa February 1938, but without being made a member of the Air Council.[1]
The ACAS post was re-established in 1985 by eliminating the Vice Chief of the Air Staff and combining the Policy and Operations two star assistant chiefs. In 1992, ACAS became a member of the Air Force Board. The ACAS is responsible for "assisting the Chief of the Air Staff in generating a balanced and integrated Royal Air Force capability and for maintaining the fighting effectiveness and morale of the Service including the development of policy."[2] One of the many duties of the ACAS is to sit on the board of the Civil Aviation Authority as a non-executive member.[3]
