10. Cabin

The Cabin Intercommunication Data System (CIDS) consists of two directors, one active and one hot standby. The CIDS communicates with cabin, passengers and crew via Decoder Encoder Units (DEUs) and is programmed and tested via a Programming and Test Panel (PTP).

The Forward Attendant Panel (FAP) is located at the purser station and consists of:

The PTP is located behind a hinged access door to the left of the FAP. It is equipped with a Cabin Assignment Module (CAM) containing airline specific data. It is the PTP communicates system status to the crew.

The Aft Attendant Panel (AAP) is located at the rear left crew station. It allows control of a subset of cabin systems.

An Attendant Indication Panel (AIP) is located near each main cabin crew station. It displays communication and system related messages.

Area Call Panels (ACP) are located in the ceiling at either end of the cabin. Their indications are:

Pink steady or pink flashing

Crew communication

Blue steady

Passenger call

Amber steady

Lavatory call

Amber flashing

Lavatory smoke detection

The controls on the main doors consist of an opening handle with an associated mechanical door status indicator located towards the top of the door and a slide arming lever with associated status indicator just above the lever. An emergency opening cylinder and assocated pressure gauge are situated in the door support and a white gust lock button is located on top of the door support. Each door has an observation window, and two indicators are fitted at the bottom of this window. The first is a cabin pressure indicator which flashes red if the cabin is still pressurised when the engines are shut down and the slide is disarmed. A white indicator illuminates as the opening handle is first moved if the slide is armed.

The overwing exits have a single opening handle with a protective cover. If the cover is removed, a white "SLIDE ARMED" light will illuminate.

The slides deploy automatically if the doors are opened when the slide is armed. A red manual inflation handle is provided on the right side of the girt bar for the main doors and in the exit frame for the overwings. The main door slides are single lane, and the overwing slides are dual lane. All slides are fitted with integral lighting and emergency lights are fitted to the aircraft below the overwing exits to illuminate the route to the slide. Red handles are fitted to the sides of the slide near the bottom to allow the slide to be used as a rag slide in case of pressure loss. The main door slides have a white handle under the girt bar cover that allows the slide to be quickly detached from the aircraft. It will remain attached to the aircraft by a tether, and a knife is provided to cut this tether. In case of ditching, it is possible to transport a slide from an inoperative door and deploy it from an operative door once that door's slide has been detached.

Emergency oxygen generators are fitted above each row of passenger seats, above each cabin crew station and in the lavatories. The generators start automatically when any of the masks attached to it are pulled down.

An emergency evacuation system is fitted, with contols on the FAP, AAP and cockpit. An EVAC panel is situated on the left of the overhead panel. The CAPT & PURS/ CAPT switch determines which stations can initiate an evacuation alert.
