Abstract
A method and apparatus for determining the severity of icing conditions for an aircraft in flight. A mobile probe projecting from a surface of the aircraft is heated to a predetermined range of temperatures, and the total power required for the heating is measured. The measured total power is divided into a basic power corresponding to the thermal exchange in dry air having the same flow parameters as those measured and a complimentary power corresponding to the evaporating of drops of water contained in the actual air. A parameter representative of the speed at which the thickness of ice increases at the surface of the aircraft is computed from the complementary power.
