How Airbus engineers are debugging the A350-XWB

Airbus has long been in a neck-and-neck race with Boeing for the lead in the airplane market. The company is making a big bet with the A350, a plane built with composite materials to make it lighter and more fuel-efficient. However, it’s also a plane designed from a clean slate instead of retrofitting an older design. That potentially attracts more attention but it also means that working out all of the bugs is a much bigger task than usual.
