Cockpit and avionics

The revised design of the cockpit dropped the A380-sized display and adopted 38 cm (15 in) LCD screens. The new six-screen configuration will have two central displays mounted one above the other (the lower one above the thrust levers) and a single (for each pilot) primary flight/navigation display, with an adjacent on-board information system screen. Airbus says the new cockpit will allow advances in navigation technology to be placed on the displays in the future plus flexibility and capacity to upload new software and to combine data from multiple sources and sensors for flight management and aircraft systems control. The A350 XWB will also feature a head-up display.

The avionics will be a further development of the integrated modular avionics (IMA) concept found on the A380. The A350's IMA will manage up to 40 functions (versus 23 functions for the A380) such as undercarriage, fuel, pneumatics, cabin environmental systems, and fire detection. Airbus says benefits will include reduced maintenance and lower weight because IMA replaces multiple processors and LRUs with around 50% fewer standard computer modules known as line-replaceable modules. The IMA runs on a 100-Mbit/s network based on the avionics full-duplex (AFDX) standard, already employed in the A380 instead of the Arinc 429 system on the A330/A340.
