Abstract
Method, device and item of equipment for filtering alarms originating from a windshear detection system embedded in an aircraft being able to emit an alarm. The aircraft has at least one sensor allowing the acquisition of a flight parameter. The device includes: units for the calculation of the second derivative of the flight parameter, units for the calculation of the absolute value of the second derivative of the flight parameter, units for the comparison of the absolute value of the second derivative of the flight parameter with a threshold C, units for evaluating whether the absolute value of the second derivative of the flight parameter exceeds the threshold Cover a duration greater than a time threshold T, and units for suppressing the alarm originating from the windshear detection system.
