Starter feature. Available on your Jet Tracker account.
Manufacturer-published distances at sea level, ISA and reference weight. Not corrected for altitude, temperature, wind or runway condition, takeoff included. Uses the declared LDA as a proxy for effective runway length (RBAC 135.361) and the most favourable threshold in calm air (135.385(b)(1)): on the day, wind may force the shorter threshold. Destination only: does not assess the alternate aerodrome (135.387). Not a substitute for the AFM or the operator's performance analysis. Rule: RBAC 135.385 and 135.398; private flying (RBAC 91) is not factored. Runways: declared distance (LDA) from AISWEB/DECEA (2026-09-05), checkable on each aerodrome chart; where DECEA publishes no declared distance, physical length from OurAirports is used.

History
- 1985 - First business jet with a full glass cockpit
Launched in 1985, the G-IV was the first bizjet in history to offer a full glass cockpit (Honeywell SPZ-8400 with 6 CRTs). It paved the way for the modern digital avionics that are now standard in all business jets.
- 1985First flight
- 1987FAA certification
- 1992 - GIV-SP in 1992 raised the bar
In 1992 Gulfstream launched the GIV-SP (Special Performance) with a higher MTOW, more efficient Tay 611-8 engines and the Honeywell SPZ-8500. More than 350 GIV-SP units produced, the most valued variant today on the used market.

Curiosities and highlights
Benefits
Real transatlantic range
4,220 nm (G-IV) to 4,350 nm (GIV-SP) allow nonstop flights NYC-London, LAX-Tokyo (with tailwind) and São Paulo-Madrid. A standard that defined what is expected of a heavy jet for 2 decades.
G300/G350/G400/G450 derived family
The entire G300, G350, G400 and G450 line (through 2018) is a direct descendant of the G-IV: same fuselage, wing and architecture. The G450 brought PlaneView and a higher MTOW, but the structure is fundamentally a refined G-IV.
Limitations
Operating cost weighs on the used market
Despite the attractive acquisition price (USD 2.8M-12M), the Tay 611s burn 480 gph and an overhaul costs USD 1.2M per engine. Operators must be ready for USD 750k/year in fixed costs + USD 5,500/hour, a barrier for owner-operators.
