"We are pursuing a two-step certification approach to keep us on track for our planned deliveries in the second quarter of 2012," said Larry Flynn, president, Gulfstream. "With the PTC in hand, our plan is to move production aircraft into final phase manufacturing to ensure customer deliveries in the second quarter of 2012."
PTCs have been common in general aviation programs over the past 15 years. Both the Gulfstream V and the Gulfstream G550 were issued PTCs before receiving full certification. The four G650 aircraft in the flight-test program have flown more than 2,225 hours during more than 675 flights. One of those aircraft has a fully outfitted interior, allowing the company to confirm weight projections and test new features, including its Cabin Essential™ design for redundant cabin systems. Seven production aircraft have flown in preparation for their induction into final phase manufacturing. More than 20 aircraft are in various stages of initial or final phase production.
Among its achievements, the G650 has flown for more than 14 consecutive hours, with flight test data confirming its ability to achieve 7,000 nm (12,964 km) at Mach 0.85. The aircraft has also demonstrated 5,000 nm (9,260 km) at Mach 0.90. With a top speed of Mach 0.925, the G650 is the world's fastest civilian jet.
"The G650 will exceed the capabilities of anything on the market, flying faster and farther, with industry-leading fuel efficiency and reduced emissions," Flynn said.
