Gulfstream has delivered the 50th Gulfstream G600 to an unnamed North American-based customer.The Gulfstream G600 entered service in August 2019 and has gained popularity over the last two years. It was the first aircraft, business or commercial, to be certified to Stage 5 noise standards, decreasing its impact on communities surrounding the airports it takes off and lands at. With a range of 6,600 nautical miles at Mach 0.85 and 5,600 nm at Mach 0.90, it is no wonder it reigns in the long-range-jet category. It may soon be upstaged, however, by the new Gulfstream G700 jet set to be delivered in 2022."The 600 dominates the sweet spot of range, speed, cabin comfort and fuel efficiency, and overwhelming market enthusiasm is exceeding even our own high expectations," said Gulfstream president Mark Burns.Its notable wing design combined with Pratt andamp; Whitney 800-series engines, greatly reduce drag and are more environmentally efficient. According to the company, nitrogen oxide emissions are 27% lower than the latest International Civil Aviation Organization Committee on Aviation Environmental Protection's international requirements, and emissions for carbon monoxide, hydrocarbons and smoke are more than 75% better than international requirements.The G600 interior can be configured for up to three living areas and a crew compartment or four living areas, and features low cabin sound levels, a low cabin altitude and 100% fresh air, all of which reduce fatigue and decrease the impacts of jet lag. The G600's 14 panoramic oval windows let in an abundance of natural light.
