The St Croix Pietenpol Aerial is an American homebuilt aircraft that was designed by Chad and Charles Willie and produced by St Croix Aircraft of Corning, Iowa, first flown in 1977. When it was available the aircraft was supplied in the form of plans for amateur construction, with partial kits available.〔Purdy, Don: ''AeroCrafter - Homebuilt Aircraft Sourcebook, Fifth Edition'', page 248. BAI Communications, 15 July 1998. ISBN 0-9636409-4-1〕 ==Design and development== The Pietenpol Aerial was conceived as a biplane adaptation of the Pietenpol Air Camper parasol wing homebuilt design. The design work was completed in 1974 and the first example flown in 1977, with the plans as supplemental drawings to the Aircamper plans. The resulting aircraft features a biplane layout, two separate tandem open cockpits with individual windshields, fixed conventional landing gear and a single engine in tractor configuration.〔 The aircraft is made from a combination of wood and welded steel tubing, all covered in doped aircraft fabric.

With full fuel of the payload for the pilot, passenger and baggage is .〔 The designers estimated the construction time from the supplied plans as 1200 hours.〔 Flight testing showed that the aircraft has shorter take-off and landing distances that the standard Aircamper, a lower stall speed and better stability in turbulence. The standard day, sea level, no wind, take off with a engine is and the landing roll is .〔 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「St Croix Pietenpol Aerial」の詳細全文を読む スポンサード リンク
