G450

The G450 is a designation for the model GIV-X, approved by the FAA on August 12, 2004, as is the G350, which has a reduced fuel capacity. Compared to the Gulfstream IV, its fuselage is 12 inches longer and the main entry door relocated aft. The Rolls-Royce Tay 611 engines are replaced by 611-8Cs with FADEC, redesigned thrust reversers, nacelles, and pylons which increases range and payload, coupled with aerodynamic improvements. Many Gulfstream V-SP improvements are used: the Honeywell advanced flight deck display suite, electrical power generation, cabin temperature control and pressurization, nose and nose landing gear. It also has an improved APU and flap/stab actuation system, redesigned main landing gear wheels and brakes, flight control system hard-over protection system.
