Each seat has a removable seat cushion, contoured back cushion with lumbar support, coat hanger, head rest and a document holder. FLIGHT COMPARTMENT FURNISHINGS PURPOSE The flight compartment has seating for the flight crew and a flight observer. It also has readily accessible normal and safety equipment. The flight compartment panels give access to the aircraft flight equipment and controls. GENERAL DESCRIPTION The flight compartment has seats for the pilot, the copilot and an observer. Crew aids are supplied to help the crew in aircraft flight operations. Insulation blankets are installed where necessary in the flight compartment and can be removed for structural inspection. Access panels in the compartment give access to the aircraft flight equipment. The floor area is covered with a foam backed vinyl-coated covering. The flight compartment furnishings include these components: • • • • • • The base frame of each seat is attached to four plate assemblies which roll on two machined tracks attached to the flight compartment floor. A roller is installed in each plate assembly to allow the seat to move freely along the tracks. Each seat is adjustable fore and aft along the floor tracks by means of a lock release lever located on the inboard side of each seat. The seat is held in place by four locking pins which engage in holes located along the length of the floor tracks. Pulling the lock release lever up unlocks the seat by disengaging the locking pins allowing the seat to move freely along the tracks. The height control lock lever, located on the outboard side of each seat, raises or lowers the seat with the help of a gas spring. The recline adjustment lever, located on the right side of each seat, reclines the back rest from a range of 7° to 34°. The seat also has controls for the adjustment of the lumbar support. Turning the control knob on the right side of the seat adjusts the support IN and OUT. Turning the knob on the left side adjusts the support UP and DOWN. The padded armrests fold up to make it easier to enter and exit the seat. The armrests can be individually adjusted UP or DOWN by a knob located at the forward end of each armrest. Pilot and Copilot Seats Observer Seat Crew Storage Floor Cover Sidewall Panels and Covering, Flight Compartment Ceiling Panels and Covering, Flight Compartment SUB-SYSTEM DESCRIPTION The flight compartment furnishings supply flight crew and observer accommodation and also normal and safety equipment. The seats have a safety harness with a crotch strap, lap belts and a shoulder harness. An inertia reel controls the movement of the shoulder harness which is spring loaded to the retracted position. The inertia reel may be operated in a manual or automatic mode. Selection of the inertia reel to lock secures the harness in position. Selection of the inertia reel to unlock lets the harness move freely until a force of 2 G or greater is applied, automatically locking the inertia reel. The inertia reel lock levers are located on the inboard side of the seats. This allows each flight crew member to access the other crew member lock lever in case of incapacitation. PILOT AND COPILOT SEATS The pilots and copilots seats are mechanically adjustable fore/aft and vertically and are installed on track rails in the flight compartment.

The seat cushions have heater pads to warm the seat pan. Each seat is heated by a 32 W heater pad. Annunciator switches located near the pilot and copilot seats in the flight compartment give manual control of the heating. Electrical power is supplied from the 28V DC right secondary bus through related flight compartment annunciator switches and relays to energize the seat heater pads. When a SEAT HEATER annunciator switch is pushed, the 28V DC right secondary bus is used to energize the related relay and heater pad. The SEAT HEATER lamps in the annunciator switch come on to show that electrical power is supplied to the heater. The relay has time delay circuit to de-energize the heater pads after 10 minutes. The heater pad also has a thermal switch to protect itself from too much heat and a fuse to protect itself from too much current.

The overhead bins are installed in the passenger compartment above the seats. They extend the full length of the passenger compartment on both sides of the aisle. They are used for carry-on luggage and portable emergency equipment storage. The bins are made from a fibreglass composite material with a honeycomb core. The interior of the bin is painted while the exterior has a plastic laminate decorative finish. The bins are attached to the aircraft structure with support brackets and bin hangers through anti-vibration mounts. Spacers are installed to keep an equal distance between each bin. Each bin has a self-latching door which opens upward and pivots at the front and rear of each bin compartment. The door is attached to the bin with gas spring actuators. The door is held in the closed position by the latch. When the latch is released, the actuators open the door at a controlled rate. The door latch assembly has a spring loaded handle which hinges on a latch pin. A set screw is located on the inside and underneath the handle and can be adjusted to prevent the handle from rattling and vibrating. Lifting the handle firmly upwards gives access to the set screw. Cove panel retention springs and fluorescent lights are located above the bins. The fluorescent lights are protected from accidental breakage by a transparent light guard. Air condition system headers with outlets and ceiling lights ballast are installed on the outboard side of the bins. An electrical wire harness with receptacles and connectors are installed on each bin.

The wardrobe is used for garment hanger bags and briefcase size bags. The space above the wardrobe is for avionics equipment. The wardrobe base is attached to the floor with screws and to the ceiling structure with fittings. The wardrobe has a self contained shelf unit with a hanger bar, honeycomb composite panels with quick disconnect latches, a floor pan and a door. The door pivots at the top and bottom on two Teflon bushing and pin assemblies and opens into the aisle. Panels within the closet compartment can easily be removed to give access to electrical equipment and utility lights. The wardrobe overhead light is controlled by a rocker switch in the flight attendants panel and powered from the 28V DC left secondary bus through a circuit breaker. The wardrobe enclosure is formed by the upper shelf unit, the floor pan and quick release sidewall panels. The floor pan is attached to the floor structure and the quick release sidewall panels connect the upper shelf to the floor pan. Removal of the sidewall panels gives access to the electrical equipment and the utility lights located in the sidewall forward of the airstair door. The wardrobe side panels are made of a honeycomb core and have a composite laminate surface. The flight attendant seat back forms part of the aft, inboard wardrobe compartment.
