Boeing said on Thursday that it finalized the underlying configuration of the 777-9 airliner, the first member of the new 777X aircraft family to be produced, and can begin the detailed design phase of the program.

The firm configuration milestone means that the Chicago-based airframe manufacturer has completed its configuration trade studies that are required to finalize the airplane’s capability and basic design. This work included the evaluation of wind tunnel tests, aerodynamic performance, and structural loads.

The next phase for the 777-9 will be the detailed design of parts, assemblies, and other systems for the plane. According to Boeing, as soon as detailed designs have been completed, production – currently slated to start in 2017 – can begin.

“The program is right where we want it to be,” said Bob Feldmann, vice president for the 777X program at Boeing. “We have an airplane and production system that are on track and on schedule, and we remain laser focused on meeting our commitments to our customers.”

The new 777X will be the largest and most fuel efficient twin-engine plane in the world, according to Boeing. It will use 12% less fuel and have 10% lower operating costs than competitive aircraft, the company said. Boeing is also promising new features that will improve passenger comfort.

The 777-9 will seat up to 414 passengers in a two-class configuration, and will be capable of flying 7,525 nautical miles or up to 8,060 nautical miles with 349 passengers on board.
