Abstract: Embodiments of the disclosure include methods and devices in which a flight parameter vector for an aircraft is automatically estimated and then compared to a threshold to determine whether the flight parameter vector is accurate. The detection device estimates a coefficient vector in an observation window, calculates an estimated flight parameter value, and minimizes an error associated with the observation window when calculating the estimated flight parameter value of the flight parameter vector. Comparisons may be performed by a failure detector or a flight control computer to determine failures impacting the flight parameter vector.

Abstract: Automatic estimation process and device for a flight parameter vector in an aircraft, as well as detection methods and assemblies for a failure affecting such a vector. The detection device (1) comprises means (5) for estimating, on an observation window, a coefficient vector allowing to determine a linear relationship between the searched flight parameter vector and explanatory values, by implementing a PLS regression, and means (5) to use such a coefficient vector so as to calculate, thru a linear modeling, an estimated value of said flight parameter vector.
