Le conteneur (20) présente en conséquence une longueur extérieure supérieure à la distance entre les deux barres à rouleaux (10) situées à l'extérieur, de l'avion commercial ainsi qu'une largeur extérieure et une hauteur extérieure appropriées pour une insertion par une porte passagers (4) de l'avion commercial. En outre, le fond du conteneur (20) est conçu de manière à rouler sur les barres à rouleaux (10) de l'avion commercial. Selon le procédé, des sièges passagers sont enlevés et les six barres à rouleaux (10) décrites sont fixées sur les glissières de sièges (3) correspondantes.
