Boeing shows off new 787-9 in air show practise video

Boeing has released video of a 787-9 Dreamliner practising for the Paris Air Show in the skies above Washington State.

The plane is in the livery of customer Vietnam Airlines and the video shows off its technical manoeuvres and what the Boeing says are its ''many capabilities.''

The demonstration Boeing is scheduled to fly June 15-18 at the 2015 Paris Air Show.
It is filmed above Moses Lake, in Washington, the base of Boeing's manufacturing operations.

Air New Zealand already has three of the 787-9 Dreamliners which it says is performing beyond expectations.

The Boeing 787-9 is the second and newest member of the 787 family, largely made of lightweight carbon fibre and with new aerodynamic features.

With the fuselage stretched 6m over the 787-8, the 787-9 can fly more passengers and more cargo further but claims fuel savings of 20 per cent over older similar size aircraft.

The Dreamliner programme was beset by delays before delivery and problems with its lithium ion batteries soon after entering service in 2011. Earlier this year airlines operating the plane were reminded of the need to periodically ''reboot'' it on the ground after concerns were raised about it being continuously run.

Thirty customers from around the world have ordered 509 787-9s as at last month.
Air New Zealand flies its Dreamliners mainly to China and Japan.
