The A350 XWB’s onboard systems are optimised to two primary criteria: robustness, for ensured reliability and operability; and simplicity, for reduced maintenance time and cost.

Many of the systems are derived from Airbus’ A380, providing the advantages of operational experience with this 21st century flagship aircraft, and ensuring a high level of maturity at the A350’s XWB entry into service.

Solid state power control technology on the A350 XWB eliminates the need for individual circuit breakers in the cockpit, cabin and electronics bay – providing a modern method of power control management throughout the aircraft.

The application of variable frequency generators – which were first introduced with the A380 – provides more power with less weight and lower maintenance costs. In addition, reliability and time between removals are dramatically increased.

Another A380-proven concept is the use of two hydraulic circuits (instead of three on other jetliners), with redundancy provided by a dual-channel electro-hydraulic backup system. In addition, A350 XWB’s hydraulics will be operated at the higher pressure level of 5,000 psi., as on the A380. The increased operating pressure reduces the size of pipes, actuators and other system components while also facilitating the overall access – leading to improved reliability and maintainability, as well as reducing weight and increasing cost savings.

Rolls-Royce’s new Trent XWB engine for the A350 XWB incorporates the latest technology for excellent fuel efficiency, low noise and reduced emission levels.
