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.〔''Air International'' September 1979, p. 112.〕 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. The first production aircraft flew on 12 August 1978. Swiss civil certification followed on 5 December of the same year, with deliveries, to Burma and Bolivia starting immediately thereafter.〔''Air International'' September 1979, p. 114.〕 The aircraft is also used by private customers and is both FAA and FOCA civil certified to comply to the general aviation regulations in Europe and the USA. The PC-7 Mk II is a development of the PC-9's airframe and avionics, fitted with the PC-7's smaller turbine to lower operating and maintenance costs. It is used by the South African Air Force, with sixty examples having been manufactured. The aircraft were assembled in South Africa from kits supplied by Pilatus. The value of the contract was estimated to be 175 million USD in 1993. Due to political considerations, the aircraft were not fitted with the armament hardpoints. Four PC-7 Mk II aircraft are used by the air force of Brunei. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pilatus PC-7」の詳細全文を読む スポンサード リンク
