Airbus says its new long-haul plane the A350, will make its maiden flight late on Friday (NZT) after having successfully passed a series of ground tests.
The company said the flight would take place at 0800 GMT at the Toulouse-Blagnac airport in southwestern France, "weather conditions permitting".
Flight test teams were, however, carrying out a final round of controls before giving their final green light.
A first flight would come days before the Paris Air Show, where Airbus and Boeing compete for the attention of the public and more importantly, plane buyers. Airbus has spent NZ$16 billion developing the A350, the company's most advanced airliner yet, with composite materials and swept wings to rival Boeing's wide-body jets.
Smaller versions of the three model of the Airbus XWB (extra wide body) plane will compete directly against Boeing's 787 Dreamliner which was plagued by years of production delays and more recently battery problems after finally delivering the aircraft to its customers. The larger version of the new Airbus will compete with Boeing's 777.
