Gulfstream: G500/600 Performance Exceeds Original Specs

Gulfstream Aerospace has revealed that ongoing flight testing of the forthcoming G500 and G600 means customers can expect improved performance when the two types go into service next year. The company made the announcement on Monday at NBAA 2017.

According to Gulfstream, the G600 will offer a maximum range of 6,500 nm/12,038 km at Mach 0.85, which is 300 nm/556 km farther than originally promised. At high-speed cruise, Mach 0.90, the G600 will cover 5,100 nm/9,445 km, also an increase of 300 nm/556 km over initial projections.

Meanwhile, the G500 will be able to fly 5,200 nm/9,630 km at the Mach 0.85 long-range cruise speed, besting the company's original estimate of 5,000-nm/9,260-km range. At high-speed, also Mach 0.90, the G500 will cruise 4,400 nm/8,149 km, extending its capabilities by 600 nm/1,111 km from original projections.

To highlight the revised range numbers, Gulfstream flew its fully outfitted G500 to Las Vegas from London, a potential city-pair record of 4,690 nm/8,686 km. The flight included an average 32-knot headwind. The city-pair record is pending confirmation with the National Aeronautic Association.

Examples of both the G500 and G600 are present at the company's NBAA 2017 static display. The G600 cabin is the longest in its class, according to the company, and can be configured for up to four living areas, including an optional fixed bed. Divans converting into beds also are available for customers wanting to take advantage of the model's revised range capabilities. The G600 cabin—which also features forward and aft lavatories, with a full-size galley—is “the most functional, flexible and comfortable in business aviation,” said Gulfstream president Mark Burns.
