Two Rolls-Royce Mk 611-8 engines provide 13,850 lbs of thrust each. Inspection interval is 8,000 hours. The Roll-Royce upgraded engine is responsible for 15% improved fuel consumption and decreased noise levels.
Another addition is the six-screen, color EFIS. The Honeywell SPZ-8000 avionics suite is found in the GIV’s cockpit. It includes Collins radios, FMS and dual Honeywell laser inertial reference systems. Triple laser INS, dual FMS and an air-to-ground telephone are options.
The GIV 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 pilot maneuverability easier. The GIV’s takeoff weight is 2,000 additional pounds than its predecessor, at 72,300 pounds. Hot-and-high performance is also improved. The GIV has a high speed cruise of 480 ktas.
Compared to the GIII, the GIV has gained 4.5 feet in usable interior space but maintains Gulfstream’s famous stand-up cabin. The cabin has a length of 45.1 feet, width of 7.3 feet, and height of 6.1 feet. Up to 19 passengers can be accommodated in the GIV comfortably. Amenities include a large galley and full-sized lavatory, including a shower.
The GIV is an ideal midsize, intercontinental-range business jet. Gulfstream’s aircraft have evolved through new technologies and improvements, and the GIV is evidence of this. With a new design, upgraded engines and additional space, the GIV offers great performance in the intercontinental class of jets; so great that Gulfstream modeled most of their latest jets off of the GIV. It is also offered in a single-pilot modification, the GIV-SP.
