Study Notes
Crew Signalling and Alerting
- The emergency crew alerting system indicates unusual behavior in the cabin or cockpit
- The system is initiated by the alert push-button from the cabin or cockpit
- It activates visual and aural warnings in the cockpit and cabin
CIDS Indicating and Control Functions
- The CIDS provides performance and operational requirements of the interfaced system on the FAP display
- The CIDS monitors and controls various systems, including:
- Emergency Lighting Power Supply
- Ice Protection and Control
- Doors/Slides
- The CIDS interface with the emergency lighting system monitors the system and carries out battery-capacity tests
CIDS Architecture
- The CIDS is a microprocessor-based system that controls and displays cabin functions for passengers and crew
- Components of the CIDS include:
- CIDS Director (DIR)
- Data links
- Decoder/Encoder Unit A (DEU A)
- Decoder/Encoder Unit B (DEU B)
- Forward Attendant Panel (FAP)
- Additional Attendant Panel (AAP)
- Area Call Panel (ACP)
- Attendant Indication Panels (AIP)
CIDS Director
- The CIDS Director (DIR) is the central control and interface component of the CIDS
- The system has two identical directors (DIRs) for redundancy, with one active and one in hot-standby mode
- Each DIR receives the same inputs and processes the information, with results checked via a crosstalk bus
Cabin Intercommunication Data System
- The Cabin Intercommunication Data System (CIDS) is used for communication between all cabin crew stations or between the cockpit and the cabin crew stations
- The system allows for announcements, music, and chimes to be broadcasted over all PA loudspeakers or passenger's headsets via the In-Flight Entertainment (IFE) system
Cabin Illumination
- The CIDS controls the illumination of different cabin areas independently
- The system has three illumination levels (bright, dim 1, and dim 2) and can be controlled by push-button switches on the FAP
Emergency-Evacuation
- The Emergency-Evacuation (EVAC) signalling system provides aural and visual signals to all crew members when activated from the cockpit or FAP
- The system prepares the crew for an evacuation from the aircraft
Cabin Network System (CNS)
- The CNS consists of:
- Ethernet Switch Unit (ESU)
- Cabin Network Server Unit (CNSU)
- Cabin Wireless LAN Unit (CWLU)
- Antenna CWLU
- The CNS enables Email services and airline-specific applications
- The CNSU does system processing and storage of data and files, and has connections with the Centralized Maintenance Computer (CMC)
