C. 飞机在起飞构型或在空中，设置停留刹车。Parking brake is set with the aircraft configured for takeoff or in the air.

D. 起落架的实际位置与起落架控制手柄的控制位置不一致。Landing gear position does not agree with landing gear control handle position.

液压系统压力读数显示白色代表系统压力（ ）。The white pressure readout of hydraulic system indicates that the pressure is（ ）.

A. ＞3200psi

B. ＞3000psi

C. ＞2800psi

判断正误True or False：引气总管被机翼防冰交输引气活门分为左右部分。The bleed air manifold is divided into left and right sections by the wing anti-ice cross bleed valve.

下列属于整体驱动发电机（IDG）组成部件的是：Which of the following is component of IDG?

A. 发电机 generator

B. 恒速驱动器 a constant speed drive (CSD)

C. 发动机附件齿轮箱 engine accessory gearbox

D. A和B A and B

判断正误True or False:
CRJ900驾驶舱内有2块跳开关面板。There are 2 CBPs in thecockpit of CRJ900 aircraft.

判断正误True or False: 如果在完成一个液压系统低压程序的过程中，另一个系统也出现失效，不必理会两个单系统故障，而应直接进行相应的双系统故障程序。If during the accomplishment of a hydraulic system low pressure procedure, a second system also fails, disregard both single system failures and proceed directly to the applicable double system failure procedure.

（案例分析）某航CRJ900在进近过程中，高度30英尺，突然跑道上闯入另外一架飞机，机组决定复飞，副驾驶操纵飞机，机长立即收到襟翼8度，造成飞机突然下沉接地，副驾驶此刻加油门至复飞推力，开始增加姿态复飞，造成机尾擦地。请分析以上机组执行任务复飞动作是否正确以及可能造成擦机尾的原因。(Case analysis) During the approach of one Airline＇s CRJ900 , at 30ft，there＇s suddenly another aircraft incursion the runway, the crew decided to go-around, the copilot took control of the aircraft, and the captain immediately retracted flaps to 8, causing the aircraft suddenly sinking to touch the ground. The copilot advanced the thrust to T0/GA at this moment and started to increase the go-around attitude, causing the tail strike.
Please analyze whether the flight crews perform the go-around maneuver correctly and the reasons that might cause the tail strike.
