Unit 6 Take-off 飞行学院 wpcluke 上海工程技术大学 Teaching Plan Composition of The Text Part 1: Before take-off Part 2: Take-off Part 3: Engine failure Part 1: Before Take-off 1. Make sure everything is ready 2. Make sure a RTO(中断 起飞) can be handled Part 2: Take-off 1. Throttles are pushed forward. V1(velocity one) is reached 2. VR (velocity-rotate)(抬头速度) is reached. The control column is pulled back and the nose of the 747 lifts or “rotates” into the air at an angle of about 12 degrees. 3. Landing gear is retracted(收回) 4. Flaps are retracted 5. The aircraft climbs away to find its cruise altitude(巡航高度). If the surrounding airspace is congested(拥挤的), The aircraft attains its desired altitude in stages. V1 and VR Takeoff decision speed (V1)(决断速度) is the calibrated(已校准的) airspeed(修正空速) on the ground at which, as a result of engine failure or other reasons, the pilot assumed to have made a decision to continue or discontinue the takeoff. VR(抬头速度) is the Rotation speed. The speed at which the aircraft's nosewheel leaves the ground. Grammar This is the point at which he must decide once and for all whether to take off or abort. Once and for all: now and for the last time; finally or completely 永远地；一次了结地；一劳永逸地 E.g: 1.Jim?said?he’s?decided?once?and?for?all?that?he’s going?to?stay?single?and?never?get?married?again. 吉姆最终决定他不结婚了，过单身生活。 2.Let's get this problem right once and for all. 咱们把这个问题彻底弄清楚吧 Part3: Engine (an engine) Failure If V<V1, the following actions should be taken without hesitation: 1. shuts all power off and begins braking. 2. raises the spoilers and reverses thrust If V>V1, things are simpler: 1. go on taking off 2. circle the airport and request to land to inspect the damage.
