Embodiment Construction

[0054] exist figure 1 Schematically represented in , and showing that the device 1 of the present invention is intended to approach the landing strip 2 along the transverse approach trajectory TA ( figure 2 ) at least vertically guides an aircraft AC, in particular a civil transport aircraft. Although in figure 2 The approach trajectory TA is shown as a straight line, but the invention is applicable to any type of approach trajectory, including a combination of one or more straight and / or curved segments.

[0055] For this purpose, such vertical guidance equipment 1 embedded in the aircraft AC consists of:

[0056] - a conventional tracking unit 3 enabling the determination of the current position P of the aircraft AC C become possible. This tracking unit 3 comprises at least one receiver 4 forming part of a satellite positioning system, for example of the GPS type;

[0057] - the assembly 5 comprises at least one but preferably a plurality of radar altimeters 6; and

Abstract

The invention relates to a method and a device for vertically guiding an aircraft during approach to a landing runway. Said device comprises a unit for extracting a linear ground profile (PT) stored in a memory, a ground height (HT) for the current distance (X) of the aircraft, determining the height (HT) of the aircraft (AC) with respect to the ground using at least one measurement taken by a radar altimeter The unit of the current altitude (RA), which uses the ground height (HT) and the current altitude (RA) to calculate the first current altitude (A1) unit of the aircraft (AC), calculates this current position (Pc) on the approach profile (PA) The altitude corresponding to the unit of the second current height of the aircraft (AC) and the unit for calculating the difference (Δ) between the first and the second current height, this difference (Δ) is transmitted to the guidance unit to guide the aircraft vertically (AC ).

Description

technical field [0001] The invention relates to a method and a device for vertically guiding an aircraft, especially a transport aircraft, during an approach (approach). [0002] More precisely, the invention is applicable to the approach of an airport landing runway along a transverse approach trajectory. Background technique [0003] Conventional systems assist the guidance of aircraft, especially civil transport aircraft, during the approach for landing on the landing runway of an airport. In particular, systems of the ILS (Instrument Landing System) type are known. Such an ILS requires ground facilities to provide each landing runway with lateral (locator beacon) and vertical (taxi) guidance axes along which the aircraft will be guided. [0004] However, such ILSs are not installed at all airports and are used on all landing runways. Therefore, to be usable at any airport, vertical guidance equipment must be capable of vertical guidance independent of ground facilitie...
