Method and device for detecting piloting conflicts between the crew and the autopilot of an aircraft

摘要

A method for detecting piloting conflicts between the crew and the autopilot of an aircraft. According to the method, an automatic trajectory is programmed by checking whether the actual values of navigation parameters converge on said corresponding desired values within a predetermined convergence period; in the case where at least one of the actual values does not converge, within the 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 the navigation parameters; and in the case where the predicted value of the particular parameter is higher than a corresponding predefined threshold, an alarm is emitted for the crew of the aircraft to notify them about a piloting conflict being able to jeopardize the flight safety of the aircraft. A device for implementing the method. An aircraft including the device.

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 via a processor 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 via a processor, at consecutive future moments, of the value of at least one particular parameter selected amongst said navigation parameters, wherein the at least one particular parameter corresponds to a different navigation parameter than does the at least one of said actual values that does not converge; 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),wherein said alarm for the crew comprises a piece of information on the origin of said piloting conflict, andwherein the piloting conflict is not predefined.
