Abstract: A method for piloting a pre-existing aircraft comprising the following steps: integrating an alternative piloting system (1) into the pre-existing aircraft; connecting the aircraft (200) and a ground station in which a ground pilot (207) is positioned; when the aircraft is in a normal state, having the aircraft piloted by a nominal crew; using detection means to detect the occurrence of an emergency situation and, when the occurrence of the emergency is detected: making the ground pilot (207) operational, so that the ground pilot can produce an aircraft ground piloting set-point; transmitting the ground piloting setpoint to the aircraft; using the alternative piloting system to acquire and transmit the ground piloting setpoint to the aircraft flight control system.

Abstract: 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.

Abstract: 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.

Abstract: A device for detecting, by a drone, at least one manned aircraft, the manned aircraft emitting at least one positioning message comprising at least one altitude data, the detection device having a receiver to receive the positioning message and to measure its reception strength, a calculator configured to compare an altitude difference with a first threshold to activate a first state of vigilance in case of exceedance, compare the reception strength with a second threshold to activate a second vigilance state in case of exceedance, and generate at least one collision warning signal if the first vigilance signal and the second vigilance signal are active simultaneously.

Abstract: The invention relates to a method for guiding an aircraft along a reference path, said method comprising: a) when the altitude of the aircraft is greater than a threshold, estimating (E1) a relative location of the aircraft in relation to a taxiing starting point using a map of the platform and reference points on the ground, b) when the altitude of the aircraft is less than said threshold and before the aircraft is located at the taxiing starting point, estimating (E2) a relative location of the aircraft in relation to the taxiing starting point using data relating to the absolute location of the aircraft and the last relative location estimated at step a), c) when the aircraft is located at the taxiing starting point, guiding (E3) the aircraft on the basis of a location of the aircraft relative to the reference path as estimated using data relating to a set of indicators on the ground.

Abstract: A method of navigation of an aerial drone in the presence of at least one intruding aircraft in an airspace zone surrounding the drone, wherein an estimated distance between the drone and the intruding aircraft is calculated based on a strength of the signal received and validated if an estimated value of an element of positioning data calculated by the drone using the estimated distance substantially corresponds to a measured value of the element of positioning data. An aerial drone designed for implementation of this method.
