The UK Military Flying Training System (UKMFTS) takes UK armed forces aircrew from initial training through elementary, basic, and advanced flying training phases, preparing them for their arrival at their designated operational aircraft units. It is operated by Ascent Flight Training, a consortium of Lockheed Martin and Babcock International under a 25-year Private Finance Initiative (PFI) contract for the UK's Ministry of Defence (MoD), with oversight from the MoD. The airworthiness authority for each aircraft type, for example, is fulfilled by military and civilian staff within Defence Equipment and Support. Apart from the overall contract, the main elements of the system include fixed-wing elementary, multi-engine and fast-jet pilot training, rear crew training and rotary-wing (helicopter) training.

No. 6 Flying Training School RAF is a Flying Training School (FTS) within No. 22 (Training) Group of the Royal Air Force that delivers flying training to University Air Squadrons and Air Experience Flights.
