Assignee: THE BOEING COMPANY
Field: Transport (Mechanical engineering)
Classification: CPC B | IPC B

Claim 0:
1. 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 an icing conditions detector configured to detect both ice water content and liquid water content, 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 a magnetostrictive ice detector configured to detect the liquid water content, 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, and 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.
