Gulfstream Aerospace Corp. announced today it has improved the payload-carrying capability and performance of its large-cabin, long-range G450.

By increasing the aircraft's maximum takeoff (MTOW) and maximum ramp weight (MRW), a 700-pound (318 kg) weight increase in the payload with full fuel — from 1,800 (816 kg) to 2,500 pounds (1,134 kg) — is possible. The MTOW is now 74,600 pounds (33,838 kg), while the MRW is 75,000 (34,019 kg). The benefit of this enhancement is the G450's ability to now carry 12 passengers with a maximum fuel load.

For a payload of 12 passengers traveling at the long-range cruise speed of Mach 0.80, the G450's range is 4,270 nautical miles (7,908 km), up from 4,170 (7,723 km). The aircraft's range with eight passengers traveling at Mach 0.80 remains at 4,350 nautical miles (8,061 km).

"The extra weight gives the aircraft more flexibility and addresses the need of operators to carry more passengers and baggage," said Pres Henne, Gulfstream senior vice president, Programs, Engineering and Test. "Additional range at higher payloads is always beneficial. These enhancements make an excellent airplane even better."

Gulfstream will incorporate the modification in production aircraft beginning in the first quarter of 2011. In-service aircraft can be modified through an aircraft service change (ASC).

Powered by two Rolls-Royce Tay Mk 611-8C engines, the G450 can fly eight passengers 4,350 nautical miles (8,061 km) nonstop at speeds of up to Mach 0.80. From Atlanta, the G450 can fly nonstop to Anchorage, Sao Paulo, Dakar, Geneva or Helsinki. One of the most dependable aircraft in its class, the G450 has a dispatch reliability rate of 99.89 percent. The G450 features PlaneView ®, the most advanced flight deck in its class, and the Gulfstream Enhanced Vision System (EVS) as standard equipment.
