Gulfstream’s G600 has begun FAA certification field performance testing close on the heels of type certification of its sibling G500.

“We continue to make steady progress toward certifying the all-new G600 later this year and beginning customer deliveries in 2019,” said Gulfstream President Mark Burns. “With the exceptional performance we’re seeing from the five flight-test aircraft in this program, I am highly confident our clients will be impressed with the aircraft we deliver. Its high-speed range, superior comfort and unmatched efficiency have already exceeded our expectations. Even at this stage in its development, the G600 is garnering attention, with its award-winning interior and seats, increased range capability and performance at high speed. The recent type certification for the G500 is added motivation and inspiration for us to bring the G600 across the finish line and into the hands of our customers.”

The G500 earned both its FAA type certification and production certificate on July 20. Customer deliveries of the aircraft will begin later this year.

The longer-range G600, meanwhile, recently completed FAA certification for ice shapes and stall speeds testing.

Since first flight, the five aircraft in the G600 flight-test program have accumulated more than 2,290 flight hours over more than 600 flights.

The G600, which made its first flight on Dec. 17, 2016, can fly 6,500 nm (12,038 km) at Mach 0.85 and 5,100 nm (9,445 km) at Mach 0.90. The maximum operating speed for the aircraft is Mach 0.925.
