Dreamliner a step closer to flight

THE Boeing Company 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 pre-test continuity checks to verify that the wiring installed in the airplane had been connected properly.

“We are very methodical in ensuring the integrity of the airplane’s systems. In completing the Power-On sequence, we have verified both that the electrical power distribution system is installed as designed and that if functions as intended.”
