卫星云图上，表现为白色、光滑、边缘整齐的云是＿＿

缝翼、襟翼和配平都由______控制和操作。The slats, flaps and trims are _______ controlled and operated.

判断正误True or False: 偏航阻尼器能够通过逐渐减弱偏航中的振荡来提高飞机的稳定性。 The yaw dampers improve the aircraft’s stability by damping out oscillations in yaw.

在放出期间，缝翼比襟翼（ ）放出。During extension，the slats extend （ ）the flaps.

在CRJ900 飞机上，安装有（ ）个独立的偏航阻尼器，在飞行中可以连续运行，以提高飞机的方向稳定性和转弯协调。On the CRJ900 aircrafts, （ ） independent yaw dampers operate continuously in flight to improve the aircraft’s directional stability and turn coordination.

横滚脱开允许飞行机组成员将______驾驶盘和相关钢索系统与______副翼系统隔离开。 Roll disconnect allows the flight crew to isolate the _____ control wheel and associated cable system from the ______ aileron system.

判断正误True or False: 在地面上，副翼的颤振阻尼器能够提供阵风锁定保护。On the ground, the aileron flutter dampers provide gust lock protection.

判断正误True or False: FCC 1控制着YD 1而FCC 2控制着YD 2。FCC 1 controls YD 1 and FCC 2 controls YD 2.

判断正误True or False: 如果副翼PCU失控，SSCU会自动点亮应该接替操纵的飞行员前面的绿色的PLT ROLL （正驾驶横滚）或CPLT ROLL （副驾驶横滚）遮光板电门/灯。If aileron PCU runaway, SSCU will illuminate the green PLT ROLL or CPLT ROLL glareshield switch/light in front of the pilot who should take control.

判断正误True or False: 有两个扰流板安定面控制组件（SSCUs），它们可以自动控制扰流板、水平安定面配平、俯仰杆力控制和方向舵行程限制的操作。There are two spoiler stabilizer control units (SSCUs) that automatically control operation of the spoilers, horizontal stabilizer trim, pitch feel control and rudder travel limiting.

判断正误True or False:地面扰流板只能在地面放出，作为地面减升功能的一部分。The ground spoilers only deploy on the ground as part of the GLD function.
