Gulfstream IV / IV-SP
Heavy Jet - 13 passengers, 4,220 nm published range
About the Gulfstream IV / IV-SP
The Gulfstream IV is the aircraft that established the modern large-cabin business jet, and with the GIV-SP it remains one of the most numerous heavy jets on charter. Two Rolls-Royce Tay engines take it 4,200 nm with four passengers aboard at Mach 0.80 to 0.85, in a stand-up cabin a little over 45 ft long with a full galley, an enclosed lavatory and baggage reachable in flight. It is the value end of the heavy-jet market: the same cabin cross-section as a G450 for meaningfully less per hour.
Who charters it
The heavy-jet workhorse when the mission is transcontinental or transatlantic and the budget will not carry a G450 or G550. It offers the same cabin cross-section as its successors at roughly $7,000 to $10,500 an hour, and there are enough of them on Part 135 certificates that availability is rarely the constraint. Two things to raise with a client. The airframes are old, with the youngest GIV-SP built in 2002, so cabin condition, connectivity and interior refurbishment vary enormously between tails and are worth confirming rather than assuming. Older Tay-powered aircraft are also noticeably louder on departure than a modern Gulfstream and face noise restrictions at some European airports. Charter hourly figures shown here are non-binding estimate ranges, not quotes.

Specifications current as of 2026-09-28. Published range assumes still air, an optimum profile, and a light payload. Rates are indicative and vary with routing, availability, and operator.
Worth knowing
- Established the large-cabin business jet class and remains among the most common heavy jets on charter
- Two Rolls-Royce Tay 611-8 turbofans rated at 13,850 lbf each
- Stand-up cabin sharing its cross-section with the later G450
- Baggage compartment accessible in flight, 169 cu ft
- More than 900 aircraft built across the GIV lineage, so operator familiarity and parts support are deep
Colorado mountain airports: capable
Rated from published numbers and its close kinship with the G450, which is rated capable here. The 77.8 ft wingspan is the same and sits comfortably inside Aspen's 95 ft limit, and the 5,300 ft sea-level takeoff distance is 300 ft shorter than the G450's. The caution is the same one and it is payload, not runway: a heavy jet at density altitude gives up fuel before it gives up runway, so get a runway analysis at weight for the specific tail. The older Tay engines also make this the louder option where noise limits apply.
Planning guidance only. The operator, the AFM performance data, and conditions on the day are the final authority.
