The Medium Support Helicopter Aircrew Training Facility (MSHATF) is a lodger unit of RAF Benson located in Wallingford, Oxon.

MSHATF contains six full mission simulators and four computer-based training classrooms. These are used to provide conversion and continuation training for RAF support helicopter crews. The facility is owned and operated by CAE Aircrew Training Services plc and training is provided through a Private Finance Initiative arrangement with the Ministry of Defence.

In addition to being used in a stand-alone mode, the Puma, 2 Merlin and 3 Chinook Simulators can also all be linked to a Tactical Control Centre via a local area network to provide realistic operational training in a synthetic environment. CAE ATS plc also offers time slots that are not being used by the RAF to other worldwide Air Forces for training purposes.
