A system for aiding the piloting of an aircraft during a runway approach includes an information source that provides information relating to the aircraft and its environment. A computation unit determines, with the aid of information provided by the information source, an energy reference profile having a trajectory reference profile and a speed reference profile that allows the aircraft to regain a stabilized approach trajectory, if it follows the reference profile. A monitor verifies that the aircraft is following the reference profile. An indicator supplies the pilot with piloting indications for piloting the aircraft so as to follow the reference profile.

The invention claimed is: 1. A system for aiding piloting of an aircraft during an approach to a runway with a view to a landing, the approach following a predetermined approach trajectory allowing the aircraft to carry out a stabilized approach to the runway, said system comprising: an information source that provides information relating to the aircraft and to its environment; a computation unit; and an indicator, wherein: said computation unit determines, with the aid of information provided by said information source, an energy reference profile, comprising a trajectory reference profile representing a preset trajectory to be followed and a speed reference profile representing a preset speed to be complied with during flight along said trajectory reference profile, that is configured to enable the aircraft to regain the predetermined approach trajectory, if it follows said energy reference profile, regardless of the initial configuration of the aircraft in terms of speed and altitude; said system furthermore comprises a monitor for verifying that the aircraft is following said energy reference profile; said indicator supplies the pilot with piloting indications that are configured to enable at least piloting of said aircraft in such a way that it follows said energy reference profile; said computation unit uses, as the predetermined approach trajectory, a trajectory that is configured to enable the aircraft to carry out a stabilized approach to the runway; and said predetermined approach trajectory exhibits a constant slope between two different predetermined altitudes, the aircraft having to exhibit a predetermined constant speed at least at the higher altitude of said two altitudes so as to be able to carry out the stabilized approach. 2. The system as claimed in claim 1, wherein said information source provides information relating to at least certain of the following data: the aerodynamic configuration of the aircraft; the position of at least one landing gear; the position of airbrakes; the geographical position of the aircraft; the speed of the aircraft; the mass of the aircraft; the altitude of the threshold of the runway; the characteristics of the wind; the exterior temperature; and the exterior pressure. 3. The system as claimed in claim 1, wherein said computation unit determines an energy reference profile that is configured to enable regaining of said approach trajectory as directly as possible, while minimizing consumption and noise, with a slope which is negative or zero. 4. The system as claimed in claim 1, wherein said computation unit comprises at least one aerodynamic model, a thrust model and a performance model. 5. The system as claimed in claim 1, wherein for determining the energy reference profile, said computation unit makes a choice among a set of predetermined possible solutions, the choice between said predetermined solutions being carried out automatically by an integrated device. 6. The system as claimed in claim 1, wherein said indicator presents, on a display screen, a characteristic sign indicating the slope to be commanded and a characteristic sign indicating the variation in progress of said slope. 7. The system as claimed in claim 1, wherein said indicator presents, on a display screen, a characteristic sign indicating the speed to be commanded and a characteristic sign indicating the variation in progress of said speed. 8. The system as claimed in claim 1, wherein said indicator presents, on a display screen, a characteristic sign indicating the altitude to be commanded and a characteristic sign indicating the variation in progress of said altitude. 9. The system as claimed in claim 1, wherein said indicator presents, on a display screen, a characteristic sign indicating the energy to be commanded and a characteristic sign indicating the variation in progress of said energy. 10. The system as claimed in claim 1, wherein said indicator presents an item of information demanding a go-around when a landing phase in progress cannot be brought to term. 11. The system as claimed in claim 1, wherein said indicator presents information relating to at least certain of the following: a modification of the aerodynamic configuration of the aircraft; extending of airbrakes; and extending of at least one landing gear.
