防冰系统可防止冰在缝翼前缘堆积，此系统包括供气管道、活门、终端开关、控制及指示器。
The wing anti-ice system prevents ice buildup on the wing leading edge slats, this system consists of air supply ducts, valves, terminal switches, controls and indications.
如此卓著的效率应当归功于低阻机翼、前缘缝翼和双开缝襟翼，以及高马赫混合式翼梢小翼。
This efficiency is due largely to the innovative design of the low-drag wing. This design includes leading-edge slats, double-slotted Fowler flaps, and high-Mach blended winglets.
