Compared to the Gulfstream IV, its fuselage is 12 inches longer and the main entry door is relocated aft. Rolls-Royce Tay611 engines are replaced by 611-8C with FADEC, redesigned thrust reverser, nacelle, and pylon 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, and nose and nose landing gear. It also has improved APU and flap/stab actuation system, redesigned main landing gear wheels and brakes, flight control system hard-over protection system.
