Classification: CPC B | IPC B

Claim 21:
22. A system comprising:
a first icing detector configured to detect a first icing condition in relation to one or more portions of an aircraft, wherein the first icing detector is proximate to a nose of the aircraft below a window and above a front landing gear, and wherein the first icing detector is configured to output a first icing signal indicative of the first icing condition;
a second icing detector configured to detect a second icing condition in relation to the one or more portions of the aircraft, wherein the second icing detector is proximate to the nose of the aircraft below the window and above the front landing gear, wherein the second icing detector is located aft in relation to the first icing detector, and wherein the second icing detector is configured to output a second icing signal indicative of the second icing condition; and
a control unit in communication with the first icing detector and the second icing detector, wherein the control unit is configured to receive the first icing signal from the first icing detector and the second icing signal from the second icing detector, wherein the control unit is further configured to distinguish, independent of water drop size or temperature, between a presence of supercooled liquid water and ice crystal icing in response to receiving one or both of the first icing signal or the second icing signal, and wherein the control unit is configured to determine an error condition in response to receiving the second icing signal but not the first icing signal.
