Example: Avionics include flight control systems.
What is a secure interface router used for?
Validate ACARS messages coming from the ground.
Example: SIRU ensures secure communication.
What ensures single direction data transfer from the avionics domain to the flight and cabin domains?
Open world diode.
Example: Diode prevents data backflow.
What controls data transfer in the cabin domain?
Cabin router unit CRU.
Example: CRU manages data flow within the cabin.
What do the cabin wireless LAN units CWLU do?
Provides a wireless network for personnel electronic devices use wifi.
Example: CWLU enables wifi connectivity for devices.
