11.21 Information Systems Flashcards
What is the purpose of information systems?
improve flight, cabin and maintenance operations and give services to passengers
What does the information system contain? (Composed of 2)
- Network server system (NSS)
- air traffic control (ATC)
What does the network server system host?
Onboard information system (OIS)
How Are the information system structured? (2)
- avionic world
- open world
What are avionic and open worlds?
- Avionic world = gathers aircraft systems in a secured environment
- open world =extension of the aircraft systems to the outside for airline operations and passenger needs
How is the onboard information system (OIS) shared out? And what are they called? (3)
Into 3 domains
- avionic domain
- flight operation domain
- communication and cabin domain
What does OIS stand for?
Onboard information system
What does NSS stand for?
Network server system
What does the avionic domain supply? (4)
- tools to support maintenance
- recording capability of a/c parameters
- electronic documentation related to flight, maintenance and cabin operations
- servicing tool
What does flight operation domain supply? (5)
- Performance computation tools
- operation electronic documentation related to flight ops
- Tools to support navigation
- communication management services for data exchanged with aoc centres
- tools to support maintenance
What does the communication and cabin domain supply? (3)
- pax services (email and internet)
- communication management
- Tools to support maintenance
What is the avionic domain composed of? (4)
- 2 servers
- 2 redundant routers
- 1 secure interface router unit
- 2 secured communication interfaces
What supplies aircraft parameters and avionic data from avionic world to the NSS and OIS?
Centralised data acquisition module (CDAM)
What does the open world diode do?
Allows a unidirectional data flow from the avionic world
Where is the avionic world accessible from?
Flight deck, cabin and other various points via HMI’s
What is the flight operations domain composed of? (4)
- 1 server named “aircraft network server unit-airFraMeR” (ANSU-AFMR)
- 1 router named “aircraft router unit-AFMR” (ARU-AFMR)
- captain and first office laptop AFMR
- 1 back up laptop
Where is flight operations accessible?
Cockpit through various interfaces
What is the communication and cabin domain composed of?(3)
- cabin network server unit-passenger (CSNU-PAX)
- cabin router unit-communication (CRU-COM)
- 4 cabin wireless lan units (CWLU’s) and 4 related antennae
What does the CRU-COM route data between? (5)
- Flight operations domain
- CSNU-PAX
- satcom system
- Optional Cabin video monitoring system
- optional in flight entertainment system
What does HMI stand for?
Human machine interface
What components does the HMI’s consist of?
2 OIT’s, 2 printers and 3 laptops
What does OIT stand for?
Onboard information terminals
What does OMT stand for?
Onboard maintenance terminal
What does PMAT stand for?
Portable maintenance access terminal
What is the difference of the access to the avionic, flight ops, and cabin and communication domains when using OMT’s and for what reason is this?
Different interfaces for security reasons
