Abstract
The present invention pertains to an ice detector particularly adapted to detect the presence of water droplets capable of forming supercooled large droplet (“SLD”) icing on aircraft surfaces. The invention takes advantage of boundary layer flow patterns adjacent to the detector, and their effect on water droplets, to provide a signal indicative of SLD icing conditions when they exist. The detector is also capable of distinguishing between the presence of water droplets that cause traditional cloud icing and SLD icing.
