Why is A350 quieter?

They had very low bypass ratios and as a result, were noisy and thirsty beasts. Over the years the size of those first stage fans has grown – as has the percentage of bypass gas – to the point today where the A350 Trent XWB engine is a true giant, and the bigger the engine, the more efficient and quiet it is.

While both aircraft have much quieter cabins than their competitors, the A350 definitely feels a lot quieter than the 787, no matter which part of the plane you're sitting in. The A350 is in fact the quietest twin-engined aircraft in the skies. The only plane quieter is it's double-deckered older brother, the A380.

Haven't flown those on BA, but the A350 is much quieter than the B777 and would be my choice for that reason alone. You're also likely to have a newer cabin, unless BA refurbished the 777s. Our flight between Denver and Heathrow is on an A350.

Airbus has changed the design of its A350 flagship jet amid its dispute with Qatar Airways over peeling paint. Airbus has changed the copper foil used on its A350 aircraft, which protects from lightning strikes. In 2021, Qatar Airways sued Airbus over chipped paint that exposes the copper mesh, citing a safety risk.

Aerodynamics. Talking of the wings, they play a massive part in the aerodynamic gains in the A350 design. What makes them so special is the way they've been designed to morph in flight, changing shape for maximum aerodynamic efficiency throughout the different phases of the journey.

If you're travelling on the A380 superjumbo you have two decks to choose from – upper or lower deck. Generally, sitting on the upper deck is preferable because of the usually smaller cabin and lower density configuration (2-4-2 vs. 3-4-3). It's also quieter sitting upstairs.

However, upon the completion of the test, the aircraft entered a shallow dive and started picking up speed, before breaking the sound barrier at approximately 10,000 meters (33,000 feet).

Any plane can experience turbulence, but larger planes weigh more and don't feel the impact of wind changes as much as a smaller plane. Specifically, the Airbus A380 handles turbulence very well! The A380 is a large plane mainly used for international flights.
