11.20 - Cabin Systems (ATA 44) Flashcards
What is CIDS and where is it used?
CIDS = Cabin Intercommunication Data System
Cabin Intercommunication Data System (CIDS) includes the cabin internal communication system, cabin and cockpit communication system, the in flight entertainment (IFE) system and a system to allow passengers to communicate with the ground.
It is used on all modern and new commercial aircraft.
What does the cabin mass memory store?
The cabin mass memory system stores data that is used in the cabin, this includes cabin configuration information, audio and video files such as passenger breifing and announcements as well as In-Flight Entertainment (IFE).
What 2 networks are connected to the external communication system
Ground-based network (antennas lower fuselage)
Satellite-based network (antennas upper fuselage)
How is the cabin network distributed in the cabin, when is it not permitted to be on and can you connect your own personal computer to it?
The cabin network system is a essentially a LAN (Local Area Network) system and it’s distributed in the cabin by a process known as Multiplexing. Multiplexing is where digital data is broken into small packets, attaching an address to each packet and sending it down the data bus. At the receiving end (passenger device or IFE system), de-multiplexing occurs as data packets are converted into the required audio, visual data etc to the correct passenger.
It is not permitted to be on during takeoffs and landings
A passenger may connect their personal computer to the IFE system if available or to the onboard Wi-Fi system.
What makes up the cabin core system?
The cabin core system consists of the In-Flight Entertainment (IFE) system, External Communication system, Cabin Mass Memory system and the Cabin Monitoring system
