Almost exactly one year after its maiden flight the fifth Boeing 747-8 Freighter test aircraft took off for its round of tests on 3 February. In addition to an hour of engineering testing, the flight included a standard two-hour and 30-minute B1 flight profile, which Boeing conducts on all production airplanes prior to delivery.

Boeing’s second test aircraft in late February 2010 examined new navigation equipment. Boeing discovered a buffet problem with the third test aircraft, involving turbulence coming off the landing gear doors interfering with the inboard flaps. The fourth -8F aircraft was used to conduct the non-instrumented or minimally-instrumented tests. The 747-8F programme is due to complete all flight tests in time to enter air cargo service with first customer Cargolux by mid-year.
