- 词汇与结构The autothrottle system consists of a computer which operates the thrust levers through ________ servo assemblies.
- 词汇与结构With the PMCs ON or OFF, _______ the thrust levers full forward provides some over-boost and should be considered only during emergency situations when all other available actions have been taken and terrain contact is imminent.
- Autothrottle system can be used during all stages of flight, including takeoff, cruise, approach, holding pattern and go around.
- 词汇与结构 The reverse thrust levers ________ thrust from reverse idle to maximum reverse.
- Before the airplane begins to move, thrust must be exerted. It continues to move and gain speed until thrust and drag are equal. In order to maintain a constant airspeed, thrust and drag must remain equal, just as lift and weight must be equal to maintain a constant altitude. If in level flight, the engine power is reduced, the thrust is lessened, and the airplane slows down. As long as the thrust is less than the drag, the airplane continues to decelerate until its airspeed is insufficient to support it in the air. Likewise, if
