Abstract: A configuration system (80) arranged to configure an aircraft in a single-pilot mode and a two-pilot mode, comprising: acquisition means (84) and authentication means (83) arranged to acquire and authenticate a configuration order that defines the selected mode and controls the configuration system (80) to configure the aircraft in the selected mode; first activation means (85) arranged to activate equipment dedicated to piloting by a single-pilot on board when the aircraft is configured in single-pilot mode, and to deactivate dedicated equipment when the aircraft is configured in two-pilot mode; verification means (87) arranged to, when the aircraft is configured in the single-pilot mode, verify that single-pilot flight conditions are met and inform the sole pilot on board and a ground station of the results of these checks.

Abstract: An alternative piloting system arranged to be integrated in a pre-existing aircraft that includes original systems having flight control and autopilot systems.

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.
