AI Technical Summary

Problems solved by technology

The significant angular deviation between the SVS and ZPRL has proven to be very confusing to the pilot since it does not correspond to the usual visual order of magnitude

Embodiment Construction

[0029] The method according to the invention is implemented in a Synthetic Visualization System or SVS embedded in the aircraft. A synthetic visualization system or SVS 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 visualization device. As an example, the geolocation means is eg of the GPS (Global Positioning System) type, which may or may not be coupled / mixed with an inertial measurement unit.

[0030] The display on the screen of the visualization device represents a three-dimensional composite view of the terrain being flown through. This composite representation is calculated as a first determined distance (which is referred to as the SVS range). This view includes pilot and navigation aid symbology. It usually consists of an artificial horizon giving the altitude of the aircraft and an indicator giving the altitude and speed of...

Abstract

The present invention discloses a method for graphically representing a synthetic three-dimensional view of an external landscape in an onboard visualization system for an aircraft. The general field of the invention relates to a synthetic three-dimensional view of a graphical representation of an external landscape in an onboard visualization system for an aircraft (A), said graphical representation being displayed on a visualization screen comprising a superimposed image of the external landscape Pilot and navigation information of said aircraft on said three-dimensional composite representation calculated as a first determined distance (RSVS), characterized in that said three-dimensional composite representation is on a substantially horizontal plane relative to The axis (X) at the level of the terrain is inclined by an angle of inclination (θ) and is substantially perpendicular to the axis between the flight direction and the heading of the aircraft, said axis moving with the aircraft.

Description

technical field [0001] The field of the invention relates to human-machine interfaces for aviation applications, and more particularly, to synthetic visualization systems comprising means for displaying synthetic three-dimensional images of external landscapes. 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 geolocation system, electronic computing devices, and one or more visualization devices embedded in the cockpit of the aircraft. The geolocation system is of the GPS (Global Positioning System) type. The geolocation system may be coupled with the inertial system of the aircraft. The general geolocation system communicates at least the following parameters: the position of the aircraft...
