METHOD AND DEVICE FOR DETECTING PILOTING CONFLICTS BETWEEN THE CREW AND THE AUTOPILOT OF AN AIRCRAFT
First Claim
1. A method for detecting piloting conflicts between the crew and the autopilot of an aircraft (AC), wherein an automatic trajectory (T1, T2) is programmed, said automatic trajectory (T1, T2) being defined by values of navigation parameters desired by the crew of said aircraft (AC), comprising sequentially:
- a) checking whether the actual values of said navigation parameters converge on said corresponding desired values within a predetermined convergence period;
b) in the case where at least one of said actual values does not converge, within said convergence period, on the corresponding desired value, a predictive calculation is carried out, at consecutive future moments, of the value of at least one particular parameter selected amongst said navigation parameters; and
c) in the case where the predicted value of said particular parameter is higher than a corresponding predefined threshold, an alarm is emitted for the crew of said aircraft (AC) so as to notify them about a piloting conflict being able to jeopardize the flight safety of said aircraft (AC).

Abstract
According to the invention, the method comprises checking (in 2) that the actual values of navigation parameters become closer to desired values within a predetermined time period. If this is not the case, the method comprises carrying out a predictive calculation (in 4) of the value of at least one particular parameter at consecutive future moments, and optionally transmitting an alarm (in 6) for the crew.
