Abstract
A method and device for monitoring the validity of a parameter calculated by an anemometric unit of an aircraft may employ a first section for taking into account n first data, each dependent on the parameter being monitored and n being greater than or equal to 1. A second section takes into account p second data that each depends on a value obtained from a data source external to the anemometric unit, where P is greater than or equal to 2. A calculator calculates, for each of the second data, a difference between this second datum and a first datum of the same type. A comparator compares the absolute value of each of the calculated differences with a threshold value. A deducing section deduces from the comparisons that the monitored parameter is invalid if the absolute values of two of the various differences are greater than the corresponding threshold values.
