Revealing the outcome of recently completed flight tests, Airbus says the Rolls-Royce Trent XWB97-powered aircraft is meeting or beating performance targets. Empty weight is on specification at 129,000 kg (284,000 lb.), while noise is slightly better than expected with a 16.5 EPNdB (effective perceived noise in decibels) margin to ICAO Chapter 4 standards, allowing the aircraft to meet the stringent QC0.5/1 rules for nighttime operations at London Heathrow – a global yardstick for noise-sensitive arrivals and departures.
In recent testing the aircraft also showed better-than-expected airfield performance, with the ability to take off at more than 5.3 tonnes higher weights in hot weather conditions, 7.2 tonnes greater weights than forecast out of obstacle limited runways and 3.8 tonnes better out of high altitude airfields.
