1. A system for piloting an aircraft during an autonomous approach for the purpose of landing, said piloting system comprising:
- information sources comprised of;
a flight management computer that extracts information from a database connected to the flight management computer and determines from the extracted information a virtual approach axis for the aircraft, anda positioning system configured for determining an actual three-dimensional position of the aircraft from onboard devices and for determining precision and integrity levels of the actual three-dimensional position of the aircraft;
a processor comprising a flight guidance computer,wherein said flight guidance computer comprises;
i) a first calculator that receives information characterizing the virtual approach axis determined by the flight management computer and the actual three-dimensional position of the aircraft determined by the positioning system, and directly calculates, from the received information characterizing the actual three-dimensional position of the aircraft and the virtual approach axis, perpendicular linear distances between the actual three-dimensional position of the aircraft and the virtual approach axis, wherein the perpendicular linear distances represent a first distance calculated in a horizontal plane and a second distance calculated in a vertical plane,ii) a second calculator that further receives the information characterizing the virtual approach axis determined by the flight management computer and the actual three-dimensional position of the aircraft determined by the positioning system, and calculates, from the received information characterizing the actual three-dimensional position of the aircraft and the virtual approach axis, lateral and vertical angular deviations between the actual three-dimensional position of the aircraft and the virtual approach axis, andiii) a third calculator that calculates aircraft piloting setpoints from the perpendicular linear distances calculated by said first calculator;
a piloting aid configured to receive the aircraft piloting setpoints and assist in guiding the aircraft to land according to the aircraft piloting setpoints;
a display and control system that displays the lateral and vertical angular deviations calculated by the second calculator; and
a warning and surveillance system that carries out surveillance from the lateral and vertical angular deviations.

Abstract
A system for piloting an aircraft during an autonomous approach for the purpose of landing. The piloting system has a flight guidance computer that directly computes, with the aid of a position indication and of information characterizing a virtual approach axis, linear deviations. Another computer computes aircraft piloting instructions using the linear deviations.
