Two hinges support the sculptured ceiling panel on the outboard edge. The inboard edge fits in a groove on the center conditioned air outlet. A lanyard on the inboard edge, prevents the sculptured ceiling panel from swinging fully open.
 2.  Lowered Ceiling Panels (Fig. 1)______________________
 A.  The ceiling is lowered in galley and lavatory areas to provide space for lights, service units, galley vents, and life rafts. The lowered ceiling panels are hinged for access to these furnishings. Curved ceiling panels are outboard of the life raft compartments.
 3.  Ceiling Insulation__________________
 A.  The ceiling panels are insulated with fiberglass blankets attached to fuselage structure. The blankets thermally and acoustically insulate the passenger compartment. A waterproof covering protects the compartment from condensation.
