Claim:
An internal arrangement of walls of a fuselage of an aircraft delimiting a passenger cabin and supporting, at the upper part of said fuselage and, respectively, on each side of its longitudinal plane of symmetry, two longitudinal structural ducts spaced apart parallel to one another and through which aircraft auxiliaries run, said arrangement comprising: a longitudinal central element forming a dome connecting said structural ducts; an interior ceiling panel situated under said dome and facing toward said cabin; and two lateral cover panels arranged in such a way that: a lower edge of each lateral panel is articulated with respect to said fuselage, about a connection with a longitudinal axis, each panel thus being able to occupy a raised position in which it is connected to a respective one of said structural ducts near an upper edge of the respective structural duct and a lowered position in which it is distant from said respective structural duct; and the upper edge of each lateral panel is extended, in the raised position, beyond said respective structural duct to cover corresponding longitudinal edges of said dome and said ceiling panel.
