Monte Carlo - Emirates Airlines is in talks with British engine manufacturer Rolls-Royce to finalize an order for Trent 900 engines to power 36 Airbus A380 of the Gulf carrier that were ordered in February.

The negotiations were confirmed by Emirates President Sir Tim Clark to German news portal aero.de during an aviation conference in Monaco.

Emirate's boss said that they are close to an agreement but there are still some subtitles to be clarified.

There were speculations that the whole order could burst because of bilateral ultimatums without result. Reaching a satisfactory settlement for all parties is an important phase to ensure the deliveries of the additional A380s as planned from 2020.

So far, 90 of Emirates' A380s are equipped with GP7000 engines of Engine Alliance and 52 with Rolls-Royce's Trent 900 engines.

Emirate's boss criticizes the engine manufacturers to do very little in terms of innovation.

Emirates has been hit hard by rising oil prices, Clark also admitted.

We have huge problems with that and it hits our bottom line really hard, so our first half was bad,
said the Emirates boss,

Clark hopes the engine manufacturers will deliver more fuel-efficient drives in the future. An A380neo could use up to 15 percent less kerosene than current devices.

He challenged manufacturers to coordinate their technologies for innovations of the widebody aircraft propulsion.

I assume that we have better engines in seven to ten years than today,
Clark told aero.de.
