Boeing Achieves 787 Power On

EVERETT, Wash., June 20 /PRNewswire-FirstCall/ — The Boeing Company (NYSE: BA) has completed the Power On sequence for the first 787 Dreamliner, marking the completion of the next major milestone on the path to first flight later this year.

Power On is a complex series of tasks and tests that bring electrical power onto the airplane and begin to exercise the use of the electrical systems. The 787 is a more-electric airplane with the pneumatic, or bleed air, system being totally replaced by electronics.

“The team has made great progress in bringing the bold innovation of the 787 to reality,” said Pat Shanahan, vice president and general manager of the 787 program. “There is plenty of work to be done between now and first flight, but with every step forward we grow more and more confident.”

The Power On sequence began in early June with a series of pretest continuity checks to verify that the wiring installed in the airplane had been connected properly. Upon completion of those checks, the Boeing team plugged in an external power cart and slowly began to bring full power into each segment of the system, beginning with the flight deck displays. From that point forward, the pilot’s controls were used to direct the addition of new systems to the power grid.

    So does that mean they have finished Power On testing for ZA001? or is it still going on? And what is next step for this birdie?

    I agree I couldn’t more I am super happy for them. But what is the next major step for Boeing with this Bird?
