GE Aviation has initiated the flight test program for the GEnx-2B engine, which will power the Boeing
747-8. The engine flew aboard GE’s 747 flying testbed — a modified 747-100 — on March 24 from Victorville, Calif. Aircraft systems, instrumentation and performance were all tested during the five-hour flight, which involved altitudes up to 40,000 feet. GE plans to conduct around 40 flights through this summer, and anticipates FAA
certification of the engine this year.
