Title:
METHOD OF DETECTING A FAULT WITH THE MEANS FOR DE-ICING A PROBE FOR MEASURING A PHYSICAL PARAMETER
Document Type and Number:
WIPO Patent Application WO/2011/161377
Kind Code:
A3
Abstract:
The invention relates to a method of detecting a fault with the means for de-icing a probe for measuring a physical parameter on an aircraft engine, comprising the successive steps consisting in: - measuring a first value (T1) of the physical parameter with the aid of the probe, before starting the engine; - activating the means for de-icing the probe; - on completion of a determined duration (t2 - t1) counting from the start of de-icing, in measuring a second value (T2) of the parameter with the aid of the probe; - comparing the two values and generating a fault signal if the difference between the two values is below a determined threshold.
