Gulfstream’s ultra-large-cabin, ultra-long-range Gulfstream G650 has successfully completed its first series of flight tests, according to the company. The 1-hour and 45-minute flight tested the aircraft’s handling qualities, engine operability and flap operation. Additionally, the crew evaluated the aircraft’s pitot-static systems, avionics, hydraulic systems, electrical power generation and distribution, flight controls, and cabin environmental and pressurization controls. The evaluations were performed at intended airspeeds of up to 240 knots and desired altitudes of up to 9,500 feet. "The pilots’ reports indicate that the G650’s flying qualities were outstanding," said Pres Henne, senior vice president, Programs, Engineering and Test, Gulfstream. "With its cutting-edge technology, the aircraft performed superbly, as we expected it would. We are very excited to continue our flight-test program and look forward to certification in 2011." The G650 flight-test and certification plan involves five aircraft and more than 1,800 hours of testing. Gulfstream is working toward concurrent certification from the Federal Aviation Administration and the European Aviation Safety Agency in 2011.
