The European Union Aviation Safety Agency (EASA) has certified the Airbus A350-900 with Rolls-Royce Trent XWB-84 Enhanced Performance (EP) engine.

The Enhanced Performance capability is set to deliver one percent lower fuel consumption, which will provide airlines with a reduction in overall operating costs as well as emissions.
Whilst 1% might not sound a lot, when taken into consideration over the life of an aircraft, this can add up with reduced fuel costs (especially when multiplied over a fleet).
The Rolls Royce Trent XWB-84 EP is an evolution from the current A350-900’s engine, incorporating design improvements, including upgraded fan, compressor and turbine aerodynamics and enhanced turbine blade cooling. This certification milestone demonstrates the continuous development and improvement of the A350-900 and its Trent XWB engines since the family’s entry into service 10 years ago.
The confirmation of the EASA approval will be followed in the very near future with the FAA’s corresponding certification – paving the way for the operation of this new engine variant by airlines worldwide.
In Quotes
Julien Puyou, Airbus’ Head of the Widebody Programme said:
“With EASA’s certification of the Trent XWB-84 EP to power the A350-900, we strengthen the aircraft’s position as the long-range leader. Together with our partner Rolls-Royce, this latest evolution underscores our joint commitment to continuous improvement and innovation. The Trent XWB-84 is already among the most efficient widebody engines on the market and this enhanced version will deliver even greater performance and efficiency for our airline customers,”
Percentages Matter
Airbus continues to deploy the A350 at speed, with the company winning more than 1,300 firm orders over 60 customers worldwide.
But yet – airlines are notorious for seeking efficiencies in the cabin and on the wing (as we’ve seen at this week’s show, where saving weight in cabin, carts, partitions, electronics – the list goes on).
And as noted above, 1% in isolation isn’t a lot. But when multiplied over multiple take-offs and landings, over multiple years… the savings can come in.
Both are good for the environment and the airline’s pocket.
