M13.21 Cabin System ATA 44  13.21 Cabin System The units and components which furnish a means of entertaining the passengers and providing communication within the aircraft (Cabin Intercommunication Data System) and between the aircraft cabin and ground stations (Cabin Network Service). Includes voice, data, music and video transmissions. The Cabin Intercommunication Data System provides an interface between cockpit/cabin crew and cabin systems. These systems support data exchange of the different related LRU's and they are typically operated via Flight Attendant Panels. Prepared By: Nor Aina Musa 2  13.21 Cabin System The Cabin Network Service typically consists on a server, typically interfacing with, among others, the following systems: Data/Radio Communication, In-Flight Entertainment System. The Cabin Network Service may host functions such as: Access to pre-departure/departure reports, E-mail/intranet/Internet access, Passenger database; Cabin Core System; In-flight Entertainment System; External Communication System; Cabin Mass Memory System; Cabin Monitoring System; Miscellaneous Cabin System.

One director is active. The two others are in hot standby. The active director controls, operates and monitors passenger and cabin crew related functions as well as the cabin support systems. The active director exchanges data with them through an onboard CIDS network or directly. Moreover the 3 directors are connected to the cockpit controls and indicating and to dedicated control panels (FAPs and optional MINI-FAPs) to give interactivity to cockpit and cabin crew. They are also connected to some A/C systems to make an automatic activation of some of the CIDS functions. Prepared By: Nor Aina Musa 8  Flight Attendant Panels (FAPs) let the cabin and maintenance crew control and monitor in the whole cabin; the various cabin support systems and, the passenger and cabin crew related functions Two independent touch-screens FAPs installed: a) in the Upper Deck b) in the Main Deck.

Prepared By: Nor Aina Musa 10  Cabin Crew Related Equipment (CIDS) The ACPs are used as a remote call facility to inform cabin attendants of a PAX or interphone call, of a lavatory smoke or of an EVAC signaling. They are mainly located on the cabin ceiling above aisles The AIPs display dial and call information from Passenger Address (PA), interphone and PAX. They display also additional cabin systems information like the LAV smoke location. The optional AAPs let the attendants control certain cabin support systems and the passenger related functions in a specific cabin zone. The optional AAPs and AIPs are mainly located near the attendant stations. Each attendant station has a handset for passenger address and interphone functions.

These announcements are initiated from the cockpit using either a handset or acoustic devices and from the cabin using cabin crew stations handset. - broadcasted to the passengers through passenger’s headset via In Flight entertainment (IFE) or through all cabin loudspeakers. A PA announcement -can be direct/prerecorded voice information -used to supply prerecorded music. Prepared By: Nor Aina Musa 14  Cabin Interphone used for the telephone communication between all cabin crew stations or between the cockpit and the cabin crew stations From the cockpit the communication is established via the cockpit handset or via any acoustic device. From the cabin the communication is established via any cabin crew station handset. Prepared By: Nor Aina Musa 15  Service Interphone The service interphone system is used for the telephone communications, on ground only, between the service interphone jacks or between the service interphone jacks, the cockpit and the cabin crew stations. The service interphone jacks are located within the service areas Prepared By: Nor Aina Musa 16  Crew Signalling and Alerting There are different kinds of cockpit and cabin crew signaling and alerting functions depending on the situation. The area ready function - the cabin crew inform the purser that a dedicated cabin area is ready for takeoff/landing. - activated using the FAPs and the optional MINI-FAPs. The cabin ready signaling - the purser inform the cockpit crew that all the cabin areas are ready for takeoff/landing. -This function is activated using the FAPs. Optional sterile cockpit - cockpit crew inform the purser that they do not want to be disturbed. - this function is activated through a sterile cockpit P/B. Optional Emergency Crew Alerting System (ECAS) - to indicate a possible violent incident against passengers, cabin or cockpit crew members. - activated from the cabin (cabin alert P/B and from the cockpit via a cockpit alert P/B).

Emergency The CIDS Emergency eVACuation signaling (EVAC) function eVACuation signaling controls the evacuation signaling in all cabin areas and in the (EVAC) cockpit. In case of emergency A/C evacuation - activated either from the cockpit (via the EVAC panel) or from the cabin (via FAPs, optional AAPs or optional MINI-FAPs). Lighted Signs The CIDS lighted signs function controls directly the lighting of the exit signs or, via DEUs A, the lighting of the No Smoking (NS), or the optional Portable Electronic Devices (PED), the Fasten Seat Belts (FSB) and the Return to Seat (RTS) signs. In addition it controls, via DEUs B, the lighting of the lavatory occupied signs - manually activated from the cockpit signs panel or automatically according to A/C systems data. Prepared By: Nor Aina Musa 26  CID Function Pax Call The CIDS passenger call function is activated from the passenger seats (via IFE) and from the lavatories and is reset from the attendant stations via FAPs, optional AAPs or optional MINI-FAPs. supplies the lighting of the passenger call indications (via the ACPs and the AIPs) and the broadcasting of passenger call chimes in the cabin. IFE The CIDS exchanges with the IFE, control commands for CIDS PAX Call and reading lights operation from PAX seats and potential IFE operation from FAP. In addition the CIDS exchanges with the IFE, control commands and audio signals, for broadcasting PA announcements at the PAX seats or IFE video related audio signals in the cabin. Air The CIDS has an interface with the air conditioning system via the Conditioning ADCN to remotely control the cabin temperature in a given range. The temperature can be set via the FAPs, the MINI-FAPs (optional) or the AAPs (optional). The actual temperature of all cabin and optional zones is shown on the FAPs.
