Embodiment Construction

[0025] The method according to the invention is implemented in a synthetic viewing system or SVS onboard the aircraft. The aircraft may be a fixed wing aircraft. In this case, the landing area is the airport landing runway. The aircraft may also be a helicopter. In this case, the approach axis does not have to be physically delimited. It may be defined by the crew or by the avionics system according to various parameters such as wind, obstacles, etc. In the following, the example used is the case of landing on a landing runway.

[0026] The SVS system comprises: at least one map database, geolocation means, electronic means capable of calculating a representation of the main parameters of the aircraft, a graphics computer and at least one viewing device. For example, the geolocation device is of the type "GPS", the acronym stands for "Global Positioning System", either coupled / mixed with the inertial platform or not coupled / mixed with the inertial platform.

Abstract

The general field of the invention is that of methods of three-dimensional graphical representation of a landing runway on a viewing screen of an onboard viewing system for aircraft (A), the said graphical representation being displayed in a synthetic view of an exterior landscape. The graphical representation according to the invention comprises a line (C) disposed along the axis of the runway (P), the said line being a straight stripe inclined by an angle (alpha) of between one and a few degrees with respect to the horizontal, the said line beginning at the runway threshold.

Description

technical field [0001] The field of the invention relates to human-machine interfaces for aeronautical applications, and more particularly, to a synthetic viewing system comprising means for displaying a three-dimensional composite image of an external landscape. Background technique [0002] Modern aircraft typically have a Synthetic Vision System (SVS). The system is capable of presenting to the crew a composite image of the outside landscape, which typically includes information about piloting or navigation. [0003] An SVS system includes a map database representing terrain overflighted, a geographic positioning system, electronic computing devices, and one or more viewing devices mounted in the cockpit of the aircraft. The geolocation system is of the "GPS" type, the acronym stands for "Global Positioning System". The geolocation system may be coupled with the inertial system of the aircraft. In general, a geolocation system provides at least the following parameters...
