Avionics
The A380 employs an integrated modular avionics (IMA) architecture, first used in advanced military aircraft, such as the Lockheed Martin F-22 Raptor, Lockheed Martin F-35 Lightning II, and Dassault Rafale. The main IMA systems on the A380 were developed by the Thales Group. Designed and developed by Airbus, Thales and Diehl Aerospace, the IMA suite was first used on the A380. The suite is a technological innovation, with networked computing modules to support different applications. The data networks use Avionics Full-Duplex Switched Ethernet, an implementation of ARINC 664. These are switched, full-duplex, star-topology and based on 100baseTX fast-Ethernet. This reduces the amount of wiring required and minimises latency.
