A 747-8 has completed its first test flight this week with a package of performance improvements, including enhanced GE engines that are designed to improve fuel efficiency. The aircraft took off from Paine Field in Everett, Washington and landed at Boeing Field in Seattle approximately four hours later. “It was a great flight and the engines performed as expected," said Boeing flight test and evaluation Captain Kirk Vining. The Performance Improvement Package (PIP) includes improvements to the GEnx-2B engines and Flight Management Computer (FMC) software. The test programme also validated the design changes, demonstrating the operation of the horizontal tank fuel system on the passenger version of the 747-8. Entry into service of the new engines and FMC software will take place in late 2013, while the new configuration is set for delivery in Q1 2014, and will also be available for retrofit.
