A method for piloting a pre-existing aircraft comprising the following steps:

Method for piloting an aircraft

An acquisition and analysis device to be integrated in a pre-existing aircraft that includes original systems comprising pilot controls and also an autopilot system includes acquisition means arranged to acquire parameters produced by the original systems, and analysis means arranged on the basis of the parameters, to evaluate whether the pre-existing aircraft is normal or abnormal, and to evaluate the current stage of flight of the pre-existing aircraft, on the basis of the state of the pre-existing aircraft and of the current stage of flight of the pre-existing aircraft, to define a piloting setpoint selected from piloting setpoints comprising at least a manual piloting setpoint produced by a pilot actuating pilot controls, an autopilot setpoint produced by the autopilot system, and an alternative piloting setpoint, and to cause the selected piloting setpoint to be transmitted to the original systems of the pre-existing aircraft.

Acquisition and analysis device intended for integration into a pre-existing aircraft

An alternative piloting system arranged to be integrated in a pre-existing aircraft that includes original systems having flight control and autopilot systems. The autopilot system includes a piloting device independent of the original systems, having a positioning unit arranged to produce positioning data relating to the aircraft, and a control unit arranged to produce an alternative piloting setpoint for the aircraft; an acquisition and analysis device, including acquisition device arranged to acquire data produced by the original systems, positioning data and alternative piloting setpoint as produced by the piloting device, and decision device arranged to decide whether the alternative piloting setpoint should or should not be used for piloting the aircraft; and an interface device arranged to control the flight control system on the basis of the alternative piloting setpoint when the decision device of the acquisition and analysis device decide that said alternative piloting setpoint should be used for piloting the aircraft.

Alternative piloting system for integrating in a pre-existing aircraft

A piloting device arranged to be integrated in a pre-existing aircraft that includes original systems comprising both a flight control system and an autopilot system is distinct from and autonomous relative to the original systems and includes a positioning unit and a control unit. The positioning unit is arranged to produce positioning data for the pre-existing aircraft. The control unit is arranged to perform a geofencing function from the positioning data produced by the positioning unit and to produce an alternative piloting setpoint for the pre-existing aircraft. The alternative piloting setpoint is adapted to supplement both a manual piloting setpoint produced by a pilot of the pre-existing aircraft via the flight control system and also an autopilot setpoint produced by the autopilot system.
