abort   流產(chǎn)；飛行中斷
V1: abort decision speed   起飛中斷決定速度
(Example sentence: Below this speed the take-off can be safely aborted. After this speed there will not be sufficient runway length to allow the aircraft to decelerate to a stop.）
pivot ['piv.t]  n. ①樞(軸), 支點(diǎn) ②旋轉(zhuǎn)[擺動(dòng)]中心 ③中樞, 要點(diǎn) v. （以樞為中心而）旋轉(zhuǎn)，在樞軸上轉(zhuǎn)動(dòng)
rotation  n. 旋轉(zhuǎn)；旋度
rotation speed (Vr )：起飛時(shí)開始抬前輪時(shí)的飛行（滑跑）速度 
(Example sentences: rotation speed, at which to raise the nose for take-off.// The aircraft is permitted to accelerate to rotation speed and then rotated off the ground gently. The term rotation is used, because the aircraft pivots or rotates about its centre of gravity (c.g.) when the flight controls are used to change the aircraft attitude. Usually the rotation is approximately 10 to 15 degrees nose up compared to the position of the nose while on the ground.)
V2 – safe climb speed  安全爬升速度
(Example sentence: Below this speed aircraft cannot attain sufficient climb rate.)
