Gulfstream has provided an update on the flight-test programme for its new G700. The aircraft, which was unveiled in October 2019, has now flown more than 100 test flights. It has also completed company flutter testing and its flight envelope has been expanded at both high and low speeds.
As part of Gulfstream’s testing efforts, the aircraft also flew beyond its maximum operating speed and cruise altitude, reaching Mach 0.99 and an altitude of 54,000ft (16,459m). In typical operations, the G700 has a maximum operating speed of Mach 0.925 and a maximum cruise altitude of 51,000ft (15,545m).
“These accomplishments at this stage in flight test point to the impressive maturity of the G700 programme,” said Mark Burns, president at Gulfstream. “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. With the largest galley in the industry, the utmost in technology, and the finest, freshest cabin environment, the G700 unlocks new opportunities in business jet travel.”
Gulfstream says the aircraft features wellness features including 100% fresh, never recirculated air; a low cabin altitude; “whisper-quiet” noise levels; and the option for a circadian lighting system. The cabin also features 20 panoramic oval windows in up to five living areas and the Gulfstream-exclusive ‘ultragalley’ with more than 10ft (3m) of counter space, as well as a master suite option with stand-up shower.
The G700 is powered by Rolls-Royce Pearl 700 engines and can fly at its high-speed cruise of Mach 0.90 for 6,400 nautical miles (11,853km) or at its long-range cruise of Mach 0.85 for 7,500 nautical miles (13,890km). The G700 also includes the Gulfstream Symmetry Flight Deck with electronically linked active control sidesticks; extensive use of touchscreen technology; and Gulfstream’s Predictive Landing Performance System.
