On Feb. 3, Boeing publicly unveiled the first 787 Dreamliner to feature interior components. The third flight test airplane, ZA003, has a partial interior that provides a glimpse into the new flying experience the airplane will offer. Configured for flight-testing purposes, the interior includes instrumentation racks, flight-test equipment and workstations for engineers.

"This airplane is specifically configured to test the passenger experience elements of the airplane," said Tom Galantowicz, director of 787 Interiors, Commercial Airplanes. "Our engineers and flight-test team use a disciplined process to certify the various elements of the interior and conduct airplane-level verifications."

The interior includes 135 seats, multiple lavatories and two crew rests. Certifying the interior components involves analyses and testing of the lighting, lavatories, stowage bins, dimmable windows and galleys.

Passengers will be welcomed onto the 787 by sweeping arches, dynamic lighting, larger lavatories, more spacious luggage bins and electronic window shades whose transparency they can change during flight.

"Our team is making great progress and is looking forward to getting this airplane in the air later this month," Galantowicz added.

Flight testing will continue in the months ahead. Delivery of the first 787 to launch customer ANA (All Nippon Airways) of Japan is planned for the fourth quarter of this year.
