Gulfstream exceeds G500 and G600 planned performance

Posted 10 October 2017 · Add Comment

Gulfstream Aerospace has announced that during rigorous flight-testing its long-range Gulfstream G500 and Gulfstream G600 offer better performance than originally thought.

As a result, Gulfstream is announcing new performance standards for both aircraft.

Upon entry into service, the G600 will deliver 6,500 nautical miles/12,038 kilometers of range at Mach 0.85, 300 nm/556 km farther than the initially promised range of 6,200 nm/11,482 km. At its high-speed cruise of Mach 0.90, the aircraft will fly 5,100 nm/9,445 km, an increase of 300 nm/556 km over original projections.

The G500 can fly 5,200 nm/9,630 km at its long-range cruise speed of Mach 0.85, providing operators even greater mission flexibility over the aircraft’s original 5,000-nm/9,260-km range. At its high-speed cruise of Mach 0.90, the G500 will offer 4,400 nm/8,149 km of range, a 600-nm/1,111-km increase over its projected range of 3,800 nm/7,038 km.

 “As we methodically moved through our concurrent flight-test programs, which are going exceptionally well, we recognised we had both the time and ability to enhance G500 and G600 performance and give our customers a business-jet family that’s better than the one we had promised them,” said Mark Burns, president, Gulfstream. “Extracting more capabilities from our aircraft has become a Gulfstream hallmark, the result of creating and maintaining a culture committed to continuous improvement, listening to our customers and exceeding our promises.” 

To demonstrate its increased range, a fully outfitted G500 set a potential city-pair record between London and Las Vegas, flying 4,690 nm/8,686 km at an average speed of Mach 0.88 with a 32-knot headwind. Now in Las Vegas, both the G500 and G600 — with fully outfitted interiors — will be part of the Gulfstream static display at the NBAA Business Aviation Convention & Exhibition at Henderson Executive Airport. The city-pair record is pending confirmation with the National Aeronautic Association.

Powered by twin Pratt & Whitney Canada PW800-series engines, the G500 and G600 have a maximum operating speed of Mach 0.925 — the same as Gulfstream’s G650 and flagship G650ER.
