Ending protracted speculation about how it would address the aging fuselage cross section of its large-cabin business jets, Gulfstream Aerospace last month took the wraps off the G650, which will topple (but initially not replace) the G550 from its perch as the top Gulfstream business jet when it enters service in the first half of 2012.
Compared with its predecessor, the G650 will have a cabin 14 inches wider, three inches taller and 45 feet 6 inches long, providing 28 percent more volume and a lower cabin altitude (4,850 feet at the FL510 ceiling and a mere 2,765 feet at FL410), a larger baggage compartment (195 cu ft, 11 percent more than the G550’s, accessed by an 8-percent-larger exterior door that is four inches closer to the ground and accessible in flight up to the airplane’s certified ceiling), a larger main entry doorway (74.75 inches high) and larger cabin windows (28 inches wide versus the current 26 inches, and mounted 3.4 inches higher in the fuselage for a better viewing angle).
