CA 2731999

A flight display system provides advanced, or previewed, indications of the aircraft's position relative to an ap-proach via a primary flight display. The primary flight display displays one or both of horizontal and vertical deviation indicators with respect to the aircraft's current position prior to the aircraft reaching the final approach. A feature of the horizontal and verti-cal deviation indicators may change on the primary flight display when the aircraft reaches the final approach, such as their color. The display system may also include an approach annunciator that provides an indication of the type of approach and the naviga-tion source for the approach. The approach annunciator is displayed prior to the final approach becoming the active leg of the flight plan. The previewed information may appear automatically on the primary flight display based upon a distance of the air-craft to the airport or runway.

Linvention concerne un système décran de vol permettant de disposer dindications évoluées, ou faisant lobjet dune prévisualisation, sur la position de lavion relativement à une approche, via un écran de vol primaire. Lécran de vol primaire affiche un des deux, ou les deux, indicateurs décart horizontal et vertical relativement à la position courante de lavion, avant que lavion namorce lapproche finale. Une caractéristique des indicateurs décart horizontal et vertical, comme leur couleur, peut varier sur lécran de vol primaire lorsque lavion amorce lapproche finale. Le système décran peut également comprendre un avertisseur dapproche qui fournit une indication sur le type dapproche et la source de navigation servant à lapproche. Lavertisseur dapproche est affiché avant que lapproche finale ne devienne la partie active du plan de vol. Les informations faisant lobjet dune prévisualisation peuvent apparaître automatiquement sur lécran de vol primaire, sur la base dune distance séparant lavion de laéroport ou de la piste.
