Boeing has flipped on the power to its first 777X test aircraft, a move that allows the company to progress with a broad array of systems tests prior to next year's planned first flight. The company performed the power-up in early December at its site in Everett, where two flight-test 777Xs are in final assembly. The power-up procedure occurs when airframes move to the final position in the assembly process and enables "hundreds of functional tests" to be performed, says Boeing. (www.flightglobal.com) 更多...
