3. System Description__________________
A. Sidewall Linings and Ceiling Panels
The sidewall linings and ceiling panels in the FWD cargo compartment prevent damage from the aircraft structure. They are made of flame-resistant synthetic material and permit fast decompression. The sidewall linings and ceiling panels are attached with quick-release fasteners to:
-
the support struts
-
the cross beams
-
the cargo compartment brackets.
The sidewall linings and ceiling panels are a sandwich construction. They are made of honeycomb core, which is bonded between prepreg layers.
B. Deflector Strips
Deflector strips are installed at the center of the ceiling panels in the cargo compartment. The deflector strips keep a clearance between the top of the cargo and the components of the smoke detection and fire extinguishing system. The deflector strips also make sure that the decompression panels for a fast decompression can open.
C. Smoke Detector Panel
The FWD cargo compartment is completed with the smoke detection system. The ceiling panel has therefore a cutout for the smoke detector panel. The smoke detector panel are installed at the center of the ceiling panel between FR29 and FR30 and between FR35 and FR35.1.
D. Rapid Decompression Panels
Rapid decompression panels (blow-in and blow-out) are part of the cargo compartment linings. They are installed in the cutouts of the ceiling panels and the lateral right sidewall lining at FR28.
Catch assemblies hold them in the cutouts. The rapid decompression panels are sealed to the ceiling panels and to the sidewall lining with adhesive tape.
E. Divider Net and Door Net
There are two types of nets installed in the FWD cargo compartment. The divider net divides the cargo compartments into sections. The door net prevents damage to the cargo compartment door. The door net and the divider net are attached to the tie-down and net attachment points.
F. Tie-Down and Net Attachment Points
Screws attach the tie-down and net attachment points to the fuselage structure. These attachment points are used for:
-
the attachment of the door and divider net
-
the attachment of the straps which hold large or small items of bulk cargo.
G. Loading Area Light
The loading area light is a spotlight and is installed in the ceiling panel at the FWD cargo compartment door. The intensity of the loading area light permits to read labels on equipment near the cargo compartment door.
H. Cargo Compartment Lighting
The FWD cargo compartment has a lighting system with neon tubes and is installed in the center of the ceiling panel. Toggle switches installed at the FWD cargo compartment door control the lighting system.
