The Learjet 24 is an American six-to-eight-seat (two crew and four to six passengers) twin-engine, high-speed business jet, which was manufactured by Learjet as the successor to the Learjet 23. ==History== The Learjet 24 was designed as an improved version of the Learjet 23, which was limited to gross weight. Engineers designed the model 24 to accept up to the full gross weight permitted by FAR-25 standards. Other improvements introduced in the Learjet 24 included: * increased cabin pressurization, to allow a higher operating altitude * the addition of one extra window on each side of the cabin * more powerful engines * a new windshield * auxiliary fuel in wing tip tanks * a fire-extinguishing system for the engines With these changes, the LJ24 became the first business jet to be certified under FAR-25.〔(Learjet company timeline )〕 The first flight of a Learjet 24 took place on January 24, 1966. From May 23 to 26, 1966, a Learjet 24 flew around the world in 50 hours and 20 minutes flying time as a demonstration of its capabilities.〔 Different variants were the 24A, B, C, D, E and F, with changes of takeoff weight, in-fuselage fuel tank, range, cabin and engines. Altogether 259 Model 24s were built, and in 2001, there were still 210 Learjet 24s in use. Thirty-nine LJ24s have been lost through accidents. 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「Learjet 24」の詳細全文を読む スポンサード リンク
