Qantas Airways Ltd is set to fly again some of its Airbus A380s as it announced on Tuesday that a London-bound aircraft is scheduled to take off from Sydney on November 27, Saturday.

QF31, according to Qantas Airways chief executive Alan Joyce, would pretty much constitute the national carrier's only active A380 that the airline intends to use on its service routes between Australia and the United Kingdom.

That means the lone Airbus aircraft would be serving the destination's flight schedules pending the final outcome of the intensive engine inspection program being jointly carried out by the A380 manufacturer and Rolls Royce, which makes the Trent 900 engines that power the Qantas superjumbos.

Qantas was forced to ground its entire fleet of A380s three weeks ago when a plane that took off from Singapore suffered a blown out engine over Indonesia.

That incident was followed by series of malfunctions on other A380s that sent Rolls Royce into frantic search for the actual cause of the problem before it finally isolated the real engine issue that caused oil staining and subsequent engine fires.

Qantas said that the flight resumption of its A380s would be gradual and for the time being, a single aircraft would be utilised to serve its prime European route and along the way "Qantas will assess when and how best to deploy them as more A380s return to service."

As if in a test mode, Qantas will fly the first A380 with its engines running at below full power in observance of the airline's conservative approach to operational safety for the Airbus superjumbos.

Also, the company said on its statement that it is "voluntarily suspending A380 services on routes that regularly require use of maximum certified engine thrust and will do so until further operational experience is gained or possible additional changes are made to engines."

The operational move, according to Qantas, was independent of Airbus and Rolls Royce directives and solely the decision of the airline though it clarified that should pilots require, they could use the maximum certified thrust in the middle of a flight.
