Abstract: A panel assembly, in which the liaison between two adjacent panels is sealed by a sealing joint, where the sealing joint comprises a central part, housed in an interstice between the two panels, and an external part, facing the exterior of the panel assembly, and capable of covering at least partially the external face of the two longitudinal edges of the panels surrounding the interstice. Also, a method for mounting a panel assembly, in which two adjacent panels are fixed to one another.

Abstract: In order to not risk producing an overpressure of air in the cabin of an airplane on the ground during servicing operation on the airplane, it is appropriate to deliver the air into the cabin of the airplane only when the inlets of the air-conditioning system are open. A device for feeding electricity and air to an airplane on the ground includes means of electric production capable of being connected to at least one electric circuit of the airplane and includes means of producing a flow of air. It has, in addition, a means of determining whether the airplane is actually switched on electrically or is not actually switched on electrically and means for inhibiting the flow of air delivered toward the airplane when the airplane is not actually switched on electrically, that is, as long as it is uncertain whether the inlets of the air-conditioning system are opened.
