Boeing has completed the power-on sequence for the first 787 Dreamliner, the company announced today. The process began early this month with a series of pre-test continuity checks to verify proper wiring connections. 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, engineers used the pilot’s controls to direct the addition of new systems to the power grid.

At each step of the testing, power flows into one additional area, where gauges verify that the proper level of electrical power reached the intended area.
