A test flight is a normal step in aircraft production and takes place prior to the delivery of the aircraft to the customer. Following the flight, the aircraft will go through a few more weeks of final delivery preparations.
Airbus cautions that with any test flight, weather or other external factors could affect the decision to fly, right up to take-off. Be sure to follow the Airbus in the U.S. on Facebook and Twitter for the most up-to-date information about the flight, and photos after the completion of the flight.
