About the Gulfstream G100

Type certificated 2002 Source: FAA Type Certificate Data Sheet

Overview

The Gulfstream G100 is a fast, short-field midsize business jet that began life as the IAI Astra SPX. When General Dynamics folded Galaxy Aerospace into Gulfstream in 2002, the Astra SPX was renamed the G100 with no change to the airframe, so a used listing may carry either name for the same aircraft (serial 137 and on wear the G100 plate). Its slatted wing gives balanced field lengths near 5,000 ft and landing distances around 2,600 ft, unusual for a Mach 0.82 airframe, and it holds a 45,000 ft ceiling.

Speed and short-field access are the G100’s case on the used market: it typically costs less to acquire than a Learjet 60, Citation VII, or Hawker 800XP and matches them on pace. The trade is cabin width and fuel economy, so the real question is whether speed per acquisition dollar outweighs comfort and a 207 gph burn. A buyer who wants the same basic airframe with a wider cabin should look at the later Gulfstream G150.

Key Features for GA Buyers

  • Short-field midsize: a slatted wing delivers roughly 5,000 ft balanced field and about 2,600 ft landing distance, opening airports most midsize jets cannot use.
  • Speed and altitude: Mach 0.82 cruise near 470 KTAS and a 45,000 ft ceiling, keeping it above most weather and traffic.
  • Transcontinental reach: about 2,790 nm on the brochure basis (near 2,500 nm with full NBAA IFR reserves), enough for most US coast-to-coast pairs.

Trade-offs

  • Narrow cabin: the round Astra cross-section stands up but is tight across the shoulders next to the wider Hawker 800XP; the later G150 exists specifically to widen it.
  • Fuel burn: 207 gph makes the G100 cheap to buy but not cheap to fly, the classic high-time-jet economics.
  • Engine-program exposure: the TFE731-40R is maintained on-condition and normally enrolled on a Honeywell MSP hourly program; an off-program engine near a major inspection carries large reserve risk, so program status is the single biggest used-value swing on the type.

  • Gulfstream G150 – the direct successor: the same basic airframe with a wider, longer fuselage and more range. Compare
  • Gulfstream G280 – the super-midsize step up from the same IAI and Gulfstream lineage, with a clean-sheet wing and 3,600 nm range. Compare
  • Hawker 800XP – the archetypal midsize competitor: a wider stand-up cabin against the G100’s speed and field performance. Compare
  • Learjet 60 – a same-generation midsize twinjet that climbs harder into a tighter cabin. Compare
  • Cessna Citation VII – a contemporaneous TFE731-powered midsize: comparable speed, less range. Compare
