Aircraft 2 has flown approximately 120 hours as test pilots expand the flight envelope. Meanwhile, Aircraft 3 has accumulated 40 flight hours since first flying in October 1999. Assessment of aircraft attributes continues to confirm predictions. The active vibration system has been functional since the first flight. Performance and range predictions have been validated.
Acoustic levels are below certification requirements.
Flights have been conducted at gross weights far in excess of initial certification goals with various cg locations, from full forward to full aft, at a wide range of airspeeds. Tethered hover flight, both in and out of ground effect, has recorded 31,000 pounds of lift generated, confirming projected performance. Flights continue with current emphasis focusing primarily on the handling qualities of the aircraft at various operating weights. Aircraft 4 will be completed this year, incorporating a final update to the avionics configuration, ensuring that the latest available equipment is included for certification. Aircraft 5, the utility-configured aircraft, has participated in the Paris Air Show and the Nova Scotia International Air Show as a static display.
