Aircraft piloting procedure and system

Abstract From the Canadian patent

The steering system (1) for generating steering instructions for the aircraft according to at least one control axis for instance the pitch axis, roll axis or engine thrust command comprises at least two control means (2 3), where each is capable of calculating the derivative with respect to time of the operation representing the reliance on the corresponding steering control and which takes into account the real aircraft parameters first means (4) to compare the derivatives calculated by the control means (2 3) to one another and to select a derivative and second means (10) to integrate a selected derivative so as to obtain a steering command according to the said steering axis.
