747-8 heads for old Mexico and New Mexico

Boeing started engine runs on RC001, the first 747-8 Intercontinental, at Everett on Mar 8. Engine start-up sets the clock running on the path towards flight line gauntlet and first flight later this month. Check out thisBoeing video for an interesting take on these preparations.
Boeing says the General Electric GEnx-2B engine runs began at 11:57 a.m. (PST) and lasted approximately two hours and 45 minutes. The first engine was started with bleed air from the Pratt & Whitney Canada PW901C auxiliary power unit, while the remaining three were started using the standard cross-bleed system says Boeing. The engines were powered down and inspected and will be restarted following a technical review. A flow balance test is scheduled to take place on Mar 9.

Testing of the 747-8F freighter meanwhile continues with one of the fleet, RC503, expected to fly south on Mar 9 for runway testing at Mexico’s Toluca airport. As well as being at a relatively high elevation of 8,448 ft, the airport’s main runway 15/33 is one of the longest in Latin America at 13,780 ft. Closer to home, the first stretched 747-8, RC501 is meanwhile scheduled to conduct certification brake testing at Roswell, New Mexico.
