Patent ID: 7965201

Claim:
A method in a processor device for identifying conditions conducive to the formation of ice, comprising: comparing, by the processor device, a static temperature value, representative of a static temperature external to an aircraft, to a first threshold temperature and a second threshold temperature higher than the first; comparing at least one of (a) a liquid water content value of air in an air collection passage, representative of a liquid water content external to the aircraft, to a threshold liquid water content, and (b) a dew point temperature of air in the air collection passage, representative of a dew point temperature external to the aircraft, to a threshold dew point temperature; and if the static temperature value is at or above the first threshold temperature and at or below the second threshold temperature, and at least one of (a) the liquid water content value is at or above the threshold liquid water content, and (b) the dew point temperature is below the static temperature, directing an action associated with conditions conducive to ice formation.
