Abstract
A device for detecting a frosting intensity for an aircraft in flight includes a surface for collecting the frost and measuring means capable of measuring the thickness of the frost deposited on the frost collection surface. The device further includes calculation means configured to determine, at predetermined time intervals (Tsamp), the change in the thickness of the frost, and control means configured to generate an alarm signal when the difference in the thickness of the frost measured between two time intervals (Tsamp) is greater than a threshold value.
