The first fan-powered Gulfstream aircraft was introduced in 1967 and was in production until 1980 when the Gulfstream III became the business jet leader. Looking for improvements in fuel consumption and noise levels, Gulfstream engineers turned to the Rolls-Royce Tay turbofan to power the Gulfstream IV. The G-IV’s first flight was in September 1985 and it received FAA certification in April 1987. A total of 299 G-IVs had been produced up through December 31, 1995. Beginning in 1992, the Gulfstream IV Model was designated IV-SP. The SP Model features an increased ramp weight, MTOW, maximum landing weight, and maximum payload. The latest varient, the G400 was introduced in 2003 with 23 aircraft delivered.
The Gulfstream G400 is powered by 2 Rolls-Royce Tay Mk 611-8 medium-bypass, axial flow turbofan engines each flat-rated to 13,850 lbs of thrust to ISA+15C. Inspection interval on the engines is 8,000 hours.
The Gulfstream IV-SP is equipped with Honeywell’s enhanced G-IVSP package consisting of the SPZ-8000 integrated digital flight guidance system, six-screen EFIS with 8 x 8 in. displays, and either the NZ-910 FMS or, on aircraft produced after 1994, the NZ-2000 FMS with 100-waypoint flight plan capability.
The Gulfstream G400 is a twin turbofan-powered intercontinental-range business jet configured as a cantilever low wing monoplane with cantilever T-tail. The wing is constructed of aluminum and has honeycomb winglets, triplicate spoilers, aluminum ailerons, and single slotted Fowler flaps.The G400 wing has 1,200 lbs. greater fuel capacity, and 870 lbs. less structural weight than its predecessor, the Model III. The landing gear is the retractable tricycle type, with dual wheels on each unit.
The Gulfstream G400’s typical configuration seats 10-12 passengers in an executive layout, or 14-19 in higher-density arrangements. It is normally outfitted with all the amenities appropriate for long-range flights, including a large galley and a full-sized lavatory with a shower. In the Gulfstream tradition, it features a full stand-up cabin with a cabin height of 6.17 feet and a floor width of 5.5 feet.
