The European Union Aviation Safety Agency (EASA) has officially certified the Airbus A350-900 equipped with the upgraded Rolls-Royce Trent XWB-84 enhanced performance (EP) engine. This milestone introduces significant improvements in fuel efficiency, promising a one percent reduction in fuel consumption, which is expected to lower operational costs for airlines while also supporting environmental sustainability by reducing emissions.
The Trent XWB-84 EP engine marks an evolution from the current engine used in the A350-900, incorporating several technical upgrades. These include optimized aerodynamics in the fan, compressor, and turbine, as well as enhanced cooling mechanisms for the turbine blades. The improvements are the result of a comprehensive development program, which involved extensive ground and flight testing. This certification underscores the ongoing evolution of both the A350-900 and the Trent XWB engine family, which have seen continuous advancements since the aircraft’s introduction a decade ago.
With EASA approval now secured, attention will turn to the certification process by the United States Federal Aviation Administration (FAA), which is expected to be completed soon. Once approved, airlines worldwide will be able to integrate the new engine variant into their fleets.
Julien Puyou, Head of Airbus’ Widebody Programme, remarked that the certification strengthens the A350-900’s position as a long-range leader. He emphasized the company’s commitment to continuous innovation in collaboration with Rolls-Royce, noting that the Trent XWB-84, already one of the most efficient widebody engines available, will offer even more performance benefits to customers.
The A350 family remains recognized as the most modern and efficient in its class, particularly in the 300–410 seat range. Its advanced technologies, including cutting-edge aerodynamics, lightweight materials, and improved fuel efficiency, have led to a 25% reduction in fuel consumption, operating costs, and CO₂ emissions. Additionally, the A350’s Airspace cabin enhances the passenger experience with modern, comfortable amenities for both passengers and crew.
