Airbus has fully opened the flight envelope of the prototype A350-900, and confirmed plans to perform a fly-past at the Paris air show.

During a second test flight on 19 June the twinjet was flown to an altitude of 42,000ft and accelerated to M0.89, beyond its typical cruise speed of M0.85.

After departing Toulouse the aircraft performed several runs over the Bay of Biscay, parallel to the western French coast.

Airbus says the flight envelope was "cleared completely" in both normal and direct law. The aircraft was also flown at maximum angle-of-attack.

Chief executive Fabrice Bregier says the airframer intends to fly the aircraft over the Paris air show on 21 June at about 13:00.

He adds that the company will "definitely" conduct a similar fly-past over the Rolls-Royce plant at Derby, from where its Trent XWB engines are sourced, at a later date. "They deserve it," he says.
