Gulfstream is reporting progress in the testing program for its new flagship G700, completing more than 100 flights to date. The Savannah, Georgia-based aircraft manufacturer also has conducted flutter testing and expanded the flight envelope at both low and high speeds. In early May, the company announced that a third airframe had joined the flight-test program.

Powered by a pair of Rolls-Royce Pearl 700 engines, the G700 has an intended maximum operating speed of Mach 0.925 and a maximum cruising altitude of 51,000 feet, but as part of the test regime, the aircraft exceeded both, reaching Mach 0.99 and an altitude of 54,000 feet. The G700 will be able to fly at least 7,500 nm at a long-range cruise of Mach 0.85, Gulfstream said.

The large-cabin jet offers up to five living areas, the largest galley in the industry, a 100 percent fresh cabin air system, and the option for a master suite with shower.

“These accomplishments at this stage in flight testing point to the impressive maturity of the G700 program,” said company president Mark Burns. “We designed and developed the G700 for our customers to fly safely, securely, and efficiently while enjoying the same level of comfort as they do on the ground.”
