Gulfstream G150

Built 2006–2017Out of production2 pilots

The last and largest of IAI's Westwind and Astra family; it replaced the G100 and ended production in 2017.

71JetGrade70 = typical for midsize jets

The G150 flies about 2,950 nm with four passengers and cruises near 470 kt, so it crosses the country nonstop for roughly $4.2–6.4M. In exchange you get a shorter cabin than a Hawker or Citation Sovereign, awkward baggage loading and longer runway needs.

Buy it if

You regularly fly two to four people 2,000 nm or more, want coast-to-coast nonstop range with Gulfstream factory support, and your home runways are at least 5,000 ft long.

Skip it if

You often fill every seat with heavy bags, fly from short or hot-and-high runways, or want a longer cabin with room to spread out; a Citation Sovereign or Hawker 900XP fits those missions better.

Biggest compromise

Payload at full fuel. With full tanks the G150 can carry only about 850 lb, roughly four passengers with light bags, and balance limits can force a choice between full fuel and a full baggage hold.

  • Gulfstream G100 instead: The narrower predecessor costs less to buy but has a smaller cabin, older avionics and less payload with full tanks.
  • Cessna Citation Sovereign instead: A longer cabin and much shorter runway needs with similar range, for buyers who carry more people and bags.
  • Learjet 60XR instead: Similar speed and cabin size, but roughly 500 nm less range and Bombardier rather than Gulfstream support.

Nearly every G150 for sale has engines on Honeywell's pay-per-hour plan. Check that the contract transfers and whether a buy-in is owed.

Known issues

  • Engine program status drives value

    Engines off Honeywell's pay-per-hour plan face costly mid-life and core inspections; nearly every aircraft for sale is enrolled.

  • Flap and slat system fixes

    Gulfstream replaced flap and slat drive units, actuators and controllers under 2015 service bulletins; confirm they were completed.

  • Wing corrosion under flap fairings

    A 2022 directive requires inspecting and repairing debonded flap fairings and corrosion on the lower wing skin.

Gulfstream still supports the G150 through its St. Louis midsize service center and Dallas, with Duncan Aviation and others as authorized shops. Honeywell-approved shops maintain the engines.

Review

The full review

Strengths

  • About 2,950 nm with four passengers, enough for Los Angeles to New York or Teterboro to San Juan nonstop.
  • High-speed cruise of about 470 kt and a climb to 40,000 ft in under 16 minutes.
  • Gulfstream reported 99.8% dispatch reliability, and its St. Louis center still specializes in this fleet.

Limitations

  • Needs about 5,000 ft of runway at maximum weight, more than many midsize rivals.
  • Full-fuel payload is only about 850 lb, so a full cabin means carrying less fuel.
  • Cabin is 17 ft 8 in long, and most of its 80 cu ft of baggage space is a high external hold.

The Gulfstream G150 is the last of a family that began with the 1960s Jet Commander and ran through Israel Aerospace Industries' Westwind and Astra jets and the Gulfstream G100. IAI built it for Gulfstream from 2006 to 2017, and about 126 were made before Gulfstream ended production and steered midsize buyers toward the larger G280. Compared with the G100, the G150 has a fuselage about a foot wider, a slightly taller and longer cabin, a Rockwell Collins Pro Line 21 cockpit and a higher 26,100 lb maximum takeoff weight.

Pilot's take

From the cockpit, the G150 is a straightforward jet. The Pro Line 21 displays are large and logical, and pilots describe the aircraft as easy to hand-fly. It climbs quickly into the low 40s, where it settles at about 470 kt. The care goes into planning: on a hot day at a heavy weight the runway numbers grow fast, and loading needs a real weight-and-balance check when the tanks are full and the bags are heavy. Crews also mention a noisy entry door and the step ladder needed for oil checks. Plan around those and it is a capable long-range partner.

— TheJetGrade editorial

Who this is for

Owners who mostly fly two to four people on long domestic trips and want Gulfstream support at a midsize price. It suits coast-to-coast travelers better than families hauling bags out of short mountain runways.
