30-11-00 WING AND STABILIZER DE-ICE Back
A. System Function
The wing and stabilizer de-ice system removes ice which has collected on the leading edges of the wings and stabilizers.
B. System Components(Ref. Fig. 1 thru Fig. 3)
The primary components of the system are:
C. System Operation
A controlled supply of air (from the engine high-pressure compressors) inflates the de-icers boots on the leading edges of the wings and the stabilizers. If there is ice on the leading edges, the ice breaks when the pneumatic rubber boots inflate. The flow of air on the wings and the stabilizers then removes the pieces of ice.
