Gulfstream Aerospace Corp. announced the next-generation Gulfstream G500™ and Gulfstream G600™ have once again demonstrated additional range capabilities through real-time operations.
The newly increased range for the G500 and G600 apply to both the high-speed cruise of Mach 0.90 and the long-range cruise speed of Mach 0.85.
The G500 now delivers 5,300 nautical miles/9,816 kilometers at Mach 0.85 and 4,500 nm/8,334 km at Mach 0.90. The G600’s range at Mach 0.85 has improved to 6,600 nm/12,223 km and 5,600 nm/10,371 km at Mach 0.90.
In addition to the range increases, the G600 now delivers greater payload capacity with full fuel. As a result of Gulfstream’s advanced manufacturing and precision-build expertise, the G600’s basic operating weight has been reduced by 570 pounds/259 kilograms over original values, bringing its full-fuel payload capabilities up to 2,600 lbs/1,179 kg. This gives G600 operators even more flexibility.
During the flight-test program for the G500 and G600, both aircraft exceeded initial performance expectations with increased range capabilities. The G600 achieved a second high-speed cruise range increase before it entered service, gaining 700 nm/1,296 km over original projections. The maximum operating speed of both aircraft is Mach 0.925.
“What’s exciting for our existing customers is that these improvements already exist on their in-service aircraft with no modifications required,” Burns said.
