起飞后，副翼配平指示是_____，无论配平设置如何。After takeoff, the aileron trim indication is ______ regardless of trim setting.

判断正误True or False: 接通自动驾驶必须有一个偏航阻尼器接通。One yaw damper system must be engaged to engage the autopilot.

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.
