The Squirrel - once an Aérospatiale product, subsequently a Eurocopter one, and now part of the new Airbus Helicopters family - was chosen by the UK Ministry of Defence to provide single-engined rotary-wing training for all three armed services. As such, it is used by the component units of the Defence Helicopter Flying School at RAF Shawbury. Another Squirrel operator is the Central Flying School (Helicopter) Squadron, also Shawbury-based, which will send an HT.1 variant to RIAT 2016 for static display. CFS(H) trains helicopter instructors.
