ABSTRACT:
A warning system for detecting pre-flight aircraft icing employs parameter sensing means located at a plurality of locations along an aircraft structure, each of said sensing means positioned to sense an outer skin temperature of the aircraft structure at each of said locations and producing signals indicative thereof. Signal averaging means average said signals produced by said sensing means to produce signals representative of the average value of the outer skin temperature in a predefined area. Relative humidity sensing means produce a signal representative of the ambient relative humidity surrounding the aircraft structure prior to takeoff. Comparing means compare the outputs of said averaging means and said humidity sensing means with predetermined values of same defining an icing susceptibility region and produce a signal when the value of the sensed parameters falls within said region. Indicating means, connected to said comparing means and activated by a signal from the comparing means indicative of icing susceptibility, provide an indication to persons within a cockpit of the aircraft or to persons on the ground tending the aircraft of those sensed locations susceptible to icing.
