小小的疑问：320大翼防冰中，是指热的引气从笛型孔中喷出还是在大翼的管路流动，从而达到防冰的问题

A. Pneumatic Circuit

The wing ice protection system is supplied with hot air from the pneumatic system, downstream of the pre-cooler. The anti-ice control valve (in the wing, outboard of the engine pylon) isolates these two systems. A restrictor downstream of the anti-ice control valve controls the air flow.

The hot air goes through a lagged duct that connects the anti-ice control valve to the telescopic duct, inboard of RIB 13. The telescopic duct only attaches to the piccolo ducts in the slat 3. The piccolo ducts 3, 4 and 5 (that connect together with flexible ducts) release the hot air to heat the slats.
B. Air Distribution in the Slats

The piccolo ducts release the air into the slats through holes along their foward length. The air flows around the forward area of the slat then goes through acceleration slots into the rear section. It is then released overboard through the holes in the bottom surface of the slat.

流动的并且冒出，可以注意观察机翼前缘，有时候会看到有热气从前方冒出
