The invention relates to a method for the independent alignment (40) of an inertial unit to be mounted e.g. in an aircraft, characterised in that it comprises the following steps: monitoring the occurrence of a movement of the inertial unit during the alignment (40); interrupting the alignment (40) of the inertial unit in case a movement occurs; resuming the alignment (40) of the inertial unit when the movement ceases. The invention advantageously optimises the alignment duration as the latter can be carried out during all periods when no movement of the inertial unit is detected, and uniquely during said periods. The invention provides a quick and reliable alignment of the inertial unit.
L'invention concerne un procédé d'alignement autonome (40) de centrale inertielle pour instrument de bord pouvant équiper un aéronef, caractérisé en ce qu'il comprend les étapes suivantes : - surveiller l'apparition d'un mouvement de la centrale inertielle pendant l'alignement (40), - suspendre l'alignement (40) de la centrale inertielle en cas d'apparition de mouvement, - reprendre l'alignement (40) de la centrale inertielle à la disparition du mouvement. L'invention a pour avantage d'optimiser la durée de l'alignement dans la mesure où il peut être effectué pendant toutes les périodes où aucun mouvement de la centrale inertielle n'est détecté, mais uniquement pendant ces périodes. Elle permet un alignement rapide et fiable de la centrale inertielle.
