13.当飞机缝翼放出情况下，靠机身一侧反推包皮可打开（）度，另一侧打开（）度？（A）
A.33度、35度； B.35度、45度； C.33度、45度。

这题怎么解？在手册的什么地方

如果是A320的话

There are two hydraulic actuators, located between the pylon and the two half reversers. They are single-acting hydraulic actuator.
They are supplied with a hand pump connected to the connection box on the lower section of the forward frame.
A. Description/Operation

The two hydraulic actuators are located between the pylon and the two half reversers.
Each half reverser is actuated by a single-acting hydraulic actuator. They are fluid supplied by a hand pump which can be connected to the connection box on the lower section of the forward frame.
The input power is transmitted from the pump through hard line tubes and a hose to hydraulic actuator.
A door hold-open rod, located on the engine mounted adapter ring assembly, is to be used with the door opening actuator.
The system is put to return to retract hydraulic actuators under thrust reverser weight action. The orifice of the hydraulic actuator chamber rectricts the fluid flow, limiting the rate of retraction of the hydraulic actuator rod.
The thrust reverser half doors can be opened to a 45 degree position for engine removal. A placard at the door opening actuator connection point warns that the wing leading edge slat must be in the retracted position when the thrust reverser half doors are opened.
The external thrust reverser half doors can be opened to 35 degrees position. The internal half door can be opened to 33 degrees position with the wing leading slats extended.

在手册上有要求，开反推门前要确认缝翼在收回位，放缝翼时要确认反推门关好。反推门开启有两个角度，一个是35°（手册中叫正常维护位），另一个是45°（手册上叫换发位）AMM78-36-00-010-040-B中提及。据此推断在缝翼放出情况下，反推门打开的最大角度为35°，因发动机靠机身册距缝翼较近，角度要比35°小，所以选A。有不对之处还望指出。

懂了，就是缝翼缩进的时候反推能开45度，缝翼放出了靠机身一侧反推包皮可打开33度，另一侧打开35度。受到限制了

当缝翼在放出位时，打开反推门时要格外留心。

737的就不能打开

开了反推再放襟翼的话，可能会导致襟翼与反推包皮接触，损坏反推包皮，有公司发生过这种事件。
