The invention relates to a method for aiding the setting of the barometric altitude of an aircraft equipped with a means (11, 12) for determining the altitude not using the barometric pressure, determining with the aid of the means (11, 12) for determining the altitude an altitude (Zv, Zi, Zr, Zh) and its relative precision (Pzv, Pzr), comparing the determined altitude (Zv, Zi, Zr, Zh) with a barometric altitude measured aboard the aircraft, generating an alert when the discrepancy between the determined altitude (Zv, Zi, Zr, Zh) and the measured barometric altitude exceeds a predefined value and proposing a barometric altitude setting value.

The invention relates to a method of automatically managing the flight of an aircraft in turbulent air comprising notably the determination of the current speed (Vc), of an optimal turbulence speed (Vt), of a current thrust value (P). The data relating to a turbulence is acquired. An optimal turbulence speed is determined. Measuring a deviation (Δ) between the current speed (Vc) and the turbulence speed (Vt). Comparing the deviation (Δ) and a maximum deviation value (Δmax). Iterating k times of the previous three steps, to determine whether the deviation (Δ) is greater than the maximum deviation (Δmax) for the kth consecutive time, and the readjustment of the current thrust (P) so as to reduce the deviation (Δ) to a value less than that of the maximum deviation (Δmax) and to make the current speed (Vc) converge to the turbulence speed (Vt).

The present invention relates to a method for replacing legs in an air navigation procedure described as a series of legs, the legs forming part of an initial family of legs. The method includes: a step of determining a restricted family of legs included in the initial family of legs, so that each leg not belonging to the restricted family corresponds to a combination of legs belonging to the restricted family: The method also includes: a step of replacing in the navigation procedure the legs not belonging to the restricted family with combinations of legs belonging to the restricted family.

The present invention relates to a guidance method for temporarily deviating a vehicle initially following a predefined path. The method is characterized in that the modalities according to which the vehicle leaves the predefined path, accompanied by conditions based on which it rejoins it, are sent to the guided vehicle in the form of an alphanumeric message via a digital data link.

An aircraft piloting assistance method and system including determining at least one flyable slope with which the aircraft is assumed to be able to fly, based on a value of at least one flight parameter including the weight of the aircraft. The step for determining said slope or slopes with which the aircraft is able to fly, called flyable slopes is performed by a computer, and presenting the flyable slope to a decision-maker.

The subject of the present invention is a method of estimating, at any point of a path of an aircraft, characteristics of the wind making it possible to take very close account of the winds to construct predictions of the times of passage and of the consumption of the aircraft along its flight plan, and this method is characterized in that it consists in collecting, around the trajectory of the aircraft, a grid of parameter values of winds at a predetermined number of points in space, in comparing these values to those deriving from space-time wind trend models, in selecting, path section by section, the most likely model, and in interpolating, for each section, the local characteristics of the wind of all the points of interest of the trajectory.

The invention relates to a device for formulating a flight plan ensuring sufficient safety margins for a duration of a few minutes in relation to the set of flight constraints that could arise and comprising means for: detecting the surrounding moving objects (aircraft or meteorological phenomena), evaluating their type and the danger that they represent, formulating a reconfiguration flight plan ensuring a separation with these phenomena and taking best account of the constraints of the initially followed flight plan, avoiding prohibited or regulated airspaces and avoiding the surrounding relief with ad hoc operational margins.

The invention relates to a navigation aid method and device for an aircraft. The aircraft occupies a position PPOS outside its flight plan and seeks to rejoin the flight plan. The flight plan includes a succession of waypoints. A waypoint WPTi is called sequenced once the aircraft has passed by the waypoint WPTi at a lateral distance within the limits of the fixed sequencing conditions. The next unsequenced waypoint is called the active waypoint. The method includes the computation of at least one path to rejoin the flight plan from the current position PPOS, the computation of a potential active waypoint in the flight plan based on a rejoining path, the display of the potential active waypoint, if the pilot confirms the potential active waypoint, the sequencing of the waypoints situated upstream of the potential active waypoint, the said potential active waypoint becoming the new active waypoint.
摘要:
A method of optimizing a flight plan of an aircraft used in a flight management system of an aircraft is disclosed. This method makes it possible to constrain the real cost index of the mission executed to the optimal cost index CIopt predetermined by the aircraft operator, by acting on objectives ETAopt and EFOBopt of values of ETA and of EFOB to be achieved. Objectives are linked to this optimal cost index, in order to make the system return from a cost index CIm to the optimal cost index CIopt, while taking account of various constraints imposed by the ATC or the CTFM. Both constraints mext influence the cost index and constraints which limit the field of possible solutions.

The general field of the invention relates to a method of calculating a so-called continuous descent approach procedure for aircraft. The method comprises calculation steps making it possible to determine a minimum distance making it possible to attain the runway by using the highest possible descent angles allowed by the performance of the aircraft, a maximum distance making it possible to attain the runway by using the lowest possible descent angles allowed by the performance of the aircraft, a step of comparing the minimum and maximum distances with a reference distance, the continuous descent approach procedure being possible if this reference distance is less than the maximum distance and greater than the minimum distance. The method also envisages replacing certain indeterminate points of the flight plan by points arising from the minimum and maximum distance calculations.
