How Airbus Is Debugging the A350

A few times a month, Airbus Flight Test Engineer Patrick du Ché stands up from his desk, takes off his jacket and tie, walks to the coat rack in the corner of his office, and slips into a set of fire-resistant underwear, a bright-orange flight suit, and sturdy black boots. Then he walks down two flights of stairs and out onto the tarmac of Toulouse-Blagnac Airport in southern France. There, rising above a fleet of newly painted A320 short-haul jets, is an Airbus A350-XWB long-range widebody airliner—the very first of its kind. Sleek and nearly all white except for the lettering along its flank and the swirling blue-on-blue Airbus logo on the tail, it carries the official designation MSN001. Last May, in a modest employees-only ceremony, the final assembly line workers formally handed the plane over to the Flight Test Department. Or, as du Ché sees it, “They handed it to me.”

As a flight engineer and head of the department, du Ché gets first pick of the test flights. Although he describes himself as risk-averse, he tends to choose those he calls the most “interesting,” which means at the edge of the plane’s capabilities, where if something goes wrong, it could destroy the plane. Since June, du Ché and his colleagues have flown at the A350’s maximum design speed; conducted aerodynamic stalls; and taken off so slowly that the tail dragged on the ground.
