Le but de l'invention est d'augmenter la fiabilité lors de l'utilisation de la vitre dans des conditions de dégivrage, de pouvoir ouvrir la vitre en vol, de réduire les efforts sur la poignée de la vitre lors de sa fermeture, et d'assurer l'étanchéité par compression du flanc d'étanchéité sur le périmètre de la vitre. À cette fin, la vitre est capable de tourner par rapport au support avant inférieur par le biais d'une console qui est fixée à une extrémité au cadre de la vitre. L'autre extrémité de la console est capable de tourner sur un axe situé sur le support inférieur. Le mécanisme d'ouverture fermeture de la vitre comprend un mécanisme de fermeture de la vitre, un mécanisme de blocage de la vitre en position ouverte intermédiaire ou complètement ouverte, un mécanisme de blocage de la poignée de commande comportant une serrure de poignée empêchant toute possibilité de rotation de la vitre par rapport au support avant inférieur une fois la fenêtre sortie de son logement et son déplacement le long des rails de guidage lors de l'ouverture, tous les mécanismes étant actionnés depuis une même poignée.
