Title
(EN) AIRCRAFT COMPRISING AN AVIONIC SYSTEM WITH AN IMPROVED LOCATING DEVICE
(FR) AERONEF COMPRENANT UN SYSTEME AVIONIQUE AVEC DISPOSITIF DE LOCALISATION AMELIOREE
Abstract
(EN)
Aircraft (0) comprising an avionic system (1) that comprises: - a flight control unit (FCS); and - a locating device (2) that comprises a computing unit (3) and at least two inertial navigation systems for delivering raw location information (PVA1, PVA2) to the computing unit (3), which is suitable for determining critical location information (PVAN) of the aircraft using at least some of said raw location information (PVA1, PVA2). The aircraft (1) comprises: - a piece of equipment (4) that is external to the avionic system (1), which comprises at least one inertial measurement unit (C) that delivers raw location information (PVA3) of the external piece of equipment, the computing unit (3) determining said critical location information (PVAN) using this raw location information (PVA3) of the external piece of equipment (4).
(FR)
Aéronef (0) comprenant un système avionique (1) qui comprend: - une unité de commande de vol (FCS); et - un dispositif de localisation (2) qui comporte une unité de calcul (3) et au moins deux centrales de navigation inertielle pour délivrer des informations brutes de localisation (PVA1, PVA2) à l'unité de calcul (3) qui est adaptée à déterminer une information fiabilisée de localisation (PVAN) de l'aéronef en utilisant certaines au moins desdites informations brutes de localisation (PVA1, PVA2). L'aéronef (1) comporte: - un équipement externe (4) au système avionique (1) comprenant au moins une unité de mesure inertielle (C) fournissant une information brute de localisation (PVA3) de l'équipement externe, l'unité de calcul (3) déterminant ladite information fiabilisée de localisation (PVAN) en utilisant cette information brute de localisation (PVA3) de l'équipement externe (4).
