Gulfstream GIV-SP

The Gulfstream GIV-SP is a midsize cabin business jet with significant improvements, including a larger cabin, longer range, and advanced development over the earlier GII and GIII. The biggest improvement with the GIV/GIV-SP over the earlier Gulfstream models is the Rolls-Royce Tay engines which bring more efficient fuel burn and lowered noise emission. The GIV-SP is the first in the Gulfstream family to employ Goodyear Aerospace’s brake-by-wire system and a Dowty fail-passive steer-by-wire system, making maneuverability easier. The Gulfstream GIV-SP gross takeoff weight is a 1,400-pound increase over the GIV.

Two Rolls-Royce Mk 611-8 engines power the Gulfstream GIV-SP, each offering 13,850 lbs of thrust and using a combined 479 gallons per hour (GPH). The range of the GIV-SP is 4,091 nm operating under NBAA IFR 4 passengers with available fuel.

The cabin volume for the Gulfstream GIV-SP is 1,658 cubic feet. Typical configuration features 10 passengers and 2 crew seats.
