Pilatus PC-7
The Pilatus PC-7 Turbo Trainer is a low-wing tandem-seat training aircraft, manufactured by Pilatus Aircraft of Switzerland. The aircraft is capable of all basic training functions including aerobatics, instrument, tactical and night flying. It has been selected by more than 20 air forces as their ab initio trainer. Since the aircraft's introduction in 1978, close to 500 have been sold, with the majority still in service. Over one million hours have been flown by PC-7s worldwide.
Development
The PC-7 is based on the earlier piston-powered Pilatus P-3. The first prototype, modified from the prototype P-3 by replacing its Lycoming O-435 engine with a Pratt & Whitney PT6A-20 turboprop, flew on 12 April 1966, but after a crash the PC-7 programme was shelved.
In 1973, the programme was restarted and another P-3 was obtained from the Swiss Air Force. After modification, this aircraft flew on 12 May 1975. Further extensive modifications followed later in the programme, including a new one-piece wing with integral fuel tanks, an altered tailfin and a bubble canopy.
