Abstract

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).
