Abstract
A method of detecting a fault in a de-icer probe for measuring a physical parameter on an airplane engine, the method including: prior to starting an engine, measuring a first value of the physical parameter with help of the probe; activating the probe de-icer; at an end of a determined duration from a start of de-icing, measuring a second value of the parameter with help of the probe; and comparing the first and second values and generating a fault signal if the difference between the first and second values is less than a determined threshold.
