Re: Airbus reshapes A350 cabin to better accommodate 10 abreast

The faster gear retraction interests me. Airbus is predicting that with the sum total of these improvements (gear, flaps), there can be a 3.5 ton increase in payload on the A359 and a 2.5 ton increase for the A35J. They project that out of some airports, the advantage could be as big as 6 tons. Now,...
