Describing the cabin of Gulfstream’s new G650, senior v-p of programs, engineering and test Pres Henne said it began with a sketch of a cup holder and a single window. “That simple drawing led to an aircraft interior where form follows function,” he said.
Gulfstream unveiled the finished cabin at last month’s NBAA convention (see article on page 16), installed in one of the certification test flight aircraft, S/N 6004.
Big is one way to describe the cabin. There is 6 feet 3 inches of headroom in the flat-floor environment. At 8 feet 2 inches wide and 53 feet 7 inches long, it is 14 inches wider and 2 feet longer than the G550 cabin, and the G650 has 28 percent greater cabin volume than the G550.
But cabin environment is not the only standard. Studies have shown cabin altitude to increase crew and passenger fatigue, particularly on long flights–the G650 will be capable of carrying eight passengers and four crew 7,000 nm nonstop. With a cabin altitude of 4,850 feet at its ceiling of 51,000 feet, the G650 has the lowest cabin altitude in the industry, according to Gulfstream. And at 41,000 feet, the cabin altitude is as low as 2,800 feet.
