Abstract
An aircraft icing detection system detects accumulation of ice on an upper surface (12) of a wing (10) of an aircraft. The system includes an air pump (18) that delivers air through first and second conduits (24, 26). The first conduit delivers air through a first air knife (32) to openings (34) in the upper surface of the wing. The second conduit delivers air through a lower wing surface (14) through openings in a second air knife (42). When ice accumulates on the upper surface, flow from the first air knife is restricted. A differential pressure sensor (46) senses a pressure difference between the conduits and warns the pilot of possible ice accumulation by illuminating a warning light (50).
