As the Gulfstream G500 and G600 close in on expected FAA approval dates - midyear for the former and by year-end for the latter—the twinjets have each racked up transpacific flight records in their respective weight classes, Gulfstream Aerospace recently announced.
On April 20, the G500 and G600 flew from Shanghai to Honolulu at an average speed of Mach 0.90. The G500 made the flight in 8 hours and 34 minutes, with the G600 taking just one minute longer. The following day, the sister airplanes flew from Honolulu to Gulfstream's headquarters in Savannah, Georgia. At an average speed of Mach 0.90, the G500 accomplished the flight in 7 hours and 44 minutes. The G600 clocked in at 7 hours and 49 minutes.
The Gulfstream G500 and G600 (GVII) are twin-engine business jets designed and manufactured by Gulfstream Aerospace. The G500 will replace the G450, flying nearly 30 knots (56 km/h) faster and 18% farther with the same fuel burn. The larger G600 will succeed the G550. In 2017, Gulfstream Aerospace Corp. today announced that its long-range Gulfstream G500 and Gulfstream G600 offer even better performance than originally promised.
During rigorous flight testing in 2017, the all-new aircraft have exceeded expectations, regularly demonstrating capabilities beyond the company's initial projections. As a result, Gulfstream announced 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.
