The Cirrus SR20 is an American piston-engine, four-or-five-seat, composite monoplane built by Cirrus Aircraft of Duluth, Minnesota. The SR20 was the first production general aviation aircraft equipped with a parachute to lower the airplane safely to the ground after a loss of control, structural failure or mid-air collision. It was also the first manufactured aircraft with all-composite construction, flat-panel avionics and side-yoke flight controls. ==Design and development== The SR20 was first flown on 21 March 1995.〔(Aerofiles: Aircraft Ca to Ci ) Retrieved 24 July 2011.〕 FAA certification was achieved on 23 October 1998. At the time of the airplane's release, the general aviation industry was struggling; the SR20 was the first of its kind to earn FAA Part 23 certification in several years. Over a thousand SR20s have been sold since deliveries began in 1999. As of June 2015, more than 6,000 Cirrus aircraft had been delivered. One of the major selling points for the SR20 is its Cirrus Perspective avionics suite (by Garmin) with dual or screens: one primary flight display (PFD) and one multi-function display (MFD). This provides all standard communication, navigation (GPS and conventional VHF), and surveillance (Mode S transponder) functions. Other avionics features include in-flight weather information and TCAS-like traffic information. SR20s made from 1999 to 2003 were equipped with traditional analog instruments and a 10" MFD. In July 2003, Cirrus made PFDs standard on their SR-series, pioneering the use of glass cockpits in the light aircraft general aviation industry.〔(【引用サイトリンク】title=Introduction of Glass Cockpit Avionics into Light Aircraft )〕 The SR20, like the faster SR22, is equipped with the Cirrus Airframe Parachute System, a large parachute that can be deployed in an emergency to lower the entire aircraft to the ground safely.〔 As of 2015, the SR-series has deployed the system 53 times carrying 107 survivors. On 1 June 2004, the SR20 became the first aircraft to achieve the new European Aviation Safety Agency certificate for aircraft imported into the European Union. In 2004, Cirrus introduced the SR20 G2 (Generation 2) and in 2008 the SR20 G3 (Generation 3). Both were defined by airframe modifications, G2 by fuselage and G3 by wing/landing gear changes. Since 2011, simply "SR20" has been used. In 2012, "60/40 flex seating" was introduced, allowing up to three passengers in the rear with a split fold-down seat arrangement. This five-seat configuration was optional in 2012 but became standard equipment for 2013 SR20 models. 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「Cirrus SR20」の詳細全文を読む スポンサード リンク
