Honda Aircraft recently achieved new milestones during flight testing of the first conforming HondaJet (F1), which reached a maximum speed of 425 ktas, rate of climb of 3,990 fpm and maximum operating altitude of 43,000 feet. Powered by two GE Honda HF120 turbofans, the $4.5 million HondaJet is scheduled to enter service in the third quarter of next year. The next HondaJet to fly will be F2, and this is the third conforming jet. Power-on testing is complete and function testing of F2 is under way in preparation for its first flight this summer. The second conforming jet–static test article ST1–is undergoing full-airframe structural testing. Honda Aircraft technicians are installing systems on the fourth conforming HondaJet (F3), which will also join the flight-test program. The fifth jet (ST2) is slated for stress and fatigue testing, then the final test jet (F4) is expected to fly next spring to test cabin systems and function and reliability.
