…Let’s take a jet transport plane as an example and explain the takeoff. The plane starts rolling from the end of the runway, gradually accelerating, and when it reaches V R (rotation speed), the nose is raised. The plane leaves the ground and continues accelerating until it reaches an altitude of 35 feet (10.7 m), at which point it must reach V 2 (take-off safety speed, which is 1.15 to 1.20 times the stall speed depending on the model). … *Some of the terms that refer to "safe takeoff speed" are listed below.

…ジェット輸送機の場合を例にとって,まず離陸の場合を説明すると,滑走路端から滑走を始め,だんだん加速してVR(ブイアール)(ローテーション速度rotation speed)に達したら機首を引き起こす。機は地面を離れなおも加速しつつ高度35フィート(10.7m)に達するまでに,V2(ブイツー)(安全離陸速度take‐off safety speed。機種により失速速度の1.15~1.20倍とする)に達していなければならない。… ※「安全離陸速度」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
