The Pipistrel WATTsUP is an electric aircraft proof-of-concept trainer design manufactured in Slovenia by Pipistrel. The aircraft is based upon the Pipistrel Sinus and Virus and was first publicly shown at the Salon de Blois airshow, in France on 30 August 2014.〔 The proof of concept resulted in the Pipistrel Alpha Electro production aircraft. ==Design and development== The WATTsUP is a high-wing, cantilever monoplane of pod-and-boom configuration with a T-tail. The cabin has two seats in side-by-side configuration. The WATTsUP is powered by an electric motor developed by Siemens AG, that weighs just . The initial climb rate is over 5.1 m/s (1,000 ft/min).〔 The manufacturer claims the electric motor produces more power than a Rotax 912 and can be fully charged in about one hour. The airplane is expected to be capable of flying for about one hour with a 30-minute reserve and it is most efficient in the traffic pattern where as much as 13 percent of the energy is recuperated during each approach.〔 The initial base price is intended to be less than 100,000 Euros.〔 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「Pipistrel WATTsUP」の詳細全文を読む スポンサード リンク
