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).

A system for detecting accumulation of ice on a surface of an aircraft, comprising: air pump means for pumping air; a first generally horizontal extending exterior surface of an aircraft, said first surface being on an upper side of said aircraft and exposed to precipitation falling from above; at least one first opening in said first horizontally extending surface; a second surface of said aircraft, said second surface not exposed to precipitation; at least one second opening in said second surface; first conducting means for conducting air from said air pump means to said first opening; second conducting means for conducting air from said air pump means to said second opening; differential pressure sensing means for sensing a difference in pressure between said first and second conducting means; and indicating means in connection with said sensing means for indicting said pressure difference to an operator of said aircraft.
