Title
(DE) SYSTEM UND VERFAHREN ZUR STEUERUNG EINER BODENHINDERNISANZEIGE
(EN) SYSTEM AND METHOD FOR MANAGEMENT OF A GROUND OBSTACLE DISPLAY
(FR) SYSTEME ET PROCEDE DE GESTION D'UN INDICATEUR VISUEL DE PROXIMITE SOL
Abstract
(EN) Systems and methods for managing a visual display (20, 22) in a ground proximity warning system. In one embodiment, a system includes at least one aircraft sensor system (14) operable to acquire aircraft data and a ground proximity warning computer (12) coupled to the aircraft sensor system (14) that is operable to process the aircraft data to generate ground proximity warning data corresponding to a sensed ground obstruction. An indicating system (16) includes at least one visual display device (20, 22) that is operable to display terrain elevations and to display a visual symbol corresponding to at least one of the ground obstructions, wherein at least one of the computer and the visual display device is controllable to selectively alter an appearance of the visual symbol relative to the terrain elevations.
(FR) L'invention porte sur des systèmes et procédés de gestion d'un indicateur visuel (20, 22) de proximité sol. Dans une exécution, un système comporte au moins un système (14) de détection de bord fournissant des données sur l'aéronef, et un ordinateur (12) d'alerte de proximité sol traitant les données sur l'aéronef et en tirant des données d'alerte de proximité sol correspondant à un obstacle au sol détecté. L'indicateur (16) comporte au moins un écran (20, 22) présentant les reliefs du sol ainsi qu'un symbole visuel correspondant au moins à un obstacle terrestre. On peut commander l'ordinateur et/ou l'écran pour modifier sélectivement l'apparence du symbole visuel en fonction du relief du terrain.
