Claim:
1. A method of detecting an icing condition in which ice may form on a structure, the method comprising: supplying a first heater with a first power, the first heater being in thermal contact with a first region of a structure, and the first power being sufficient to heat the first region of the structure to a first temperature; supplying a second heater with a second power, the second heater being in thermal contact with a second region of the structure, and the second power being sufficient to heat the second region of the structure to a second temperature; and comparing the first and second powers to identify a difference between the first and second powers; and detecting an icing condition when the difference between the first and second powers is substantial, wherein the first and second regions are subjected to substantially the same environmental conditions, and wherein the first temperature is higher than the second temperature.
