R
R The system is composed of two ice detectors, for redundancy.
R
R The detection system is based upon the elementary detection of a small
R amount of ice build up.
R
R The length of the probe and its location on the aircraft are determined to
R anticipate safely the icing of the protected areas of the aircraft.
R
R Two levels of detection are provided:
R
R - one corresponding to elementary detections is used to generate messages
R for the engine anti ice
R
R - the other corresponding to a selected number of 7 elementary detections is
R used to generate messages for the wing anti ice.
R
R The sensing probe is driven magnetostrictively to vibrate at its resonant
R frequency of 40 KHz. Then, the weight of the accreted ice causes the
R frequency to decrease.
