Airbus , Europe's largest aerospace company, raised the prospect on Monday of a new cut in production of its A380 superjumbo because of weak sales but pledged to try to make sure the struggling project still breaks even. Airbus already plans to cut production to one superjumbo a month in 2018 from an unspecified level now and has said it needs to win more sales this year to maintain output at that new level, called rate 1 by the company's executives. At the same time, Airbus is trying to reduce its industrial costs to prevent financial losses, pending what it believes will be an upturn in sales as global air traffic continues to grow.
