A330s are used by a range of operators. Low-cost long-haul operator AirAsia X has converted 11 existing A330ceo orders to A330neos, it was announced in January 2016.
A smoother pressure profile on the inboard wing upper surface and a shortened flap track fairing to improve the shock pattern on the mid-board wing have, Airbus says, cut the A330’s drag by 1% in the cruise.
Airbus delivered the first 242-tonne A330 weight variants in 2015. The Incremental Development programme has involved introducing new parts and assembly methods for the aircraft.
Numerous avionics upgrades have been introduced to the A330, including an On-board Airport Navigation System that shows the aircraft's position on a moving map to assist with ground movements.
Cabin modifications on the A330 have included new lighting, an upgraded environmental control system and connectivity options.
The Incremental Development programme has laid the foundations for the A330neo variants, the first of which is due to fly this year.
