runway 跑道
(Example sentences: The friction between aircraft and runway will be proportional to the normal force exerted by the aircraft on the runway. The normal force will be the difference between Weight of aircraft and Lift, the friction coefficient will be typically of a magnitude of 0.02 for a standard tarmac runway.)

lead to 導(dǎo)致
abort take-ff 中斷起飛
Take-Off (Balanced) Field Length. 起飛(平衡)場地長度
(Example sentences: The required length of runway will be the sum of the distance required to get to rotation speed and the extra length required to allow for rapid braking if the pilot decides to abort take-off at the decision speed V1. This length will typically be considerably longer than the distance required to achieve flying speed)
