Verdict per regime (private, charter dry and wet) across 465 Brazilian public runways, with the margin in meters.

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

  1. 1979 - Launched in 1979, first production jet with winglets

    Certified in September 1980, it was the first production business jet to use winglets designed by Whitcomb (NASA), reducing induced drag by ~5% and extending range by 200 nm over the GII.

  2. 1979First flight
  3. 1980FAA certification
  4. 1986 - Production ended in 1987, replaced by the GIV

    202 units delivered between 1980 and 1987. Succeeded by the Gulfstream IV with Tay 611-8 engines (quieter and more economical) and a Honeywell SPZ-8400 cockpit with 6 CRTs.

  5. 1986End of production

Curiosities and highlights

Benefits

Genuine transatlantic range

3,650 nm allows nonstop New York to Geneva, redefining the standard for large business jets. It became the preferred aircraft of heads of state and Fortune 500 CEOs in the 1980s.

Platform certified for scientific missions

The SRA-1 and GIII-SP variants serve as atmospheric research and ISR platforms; NASA operates units for remote sensing and the USAF/USN still keep GIIIs on ELINT/SIGINT today.

Limitations

Fuel-hungry Spey engines

The Rolls-Royce Spey Mk 511-8 engines burn ~380 gph in cruise, 40% more than modern turbofans such as the BR710 or Tay 611-8. Fuel cost makes the GIII expensive for private operation today.

Curiosities

C-20, the USAF/USN military variant

The Pentagon acquired 17 units as C-20A/B/C/D/E to transport generals and for SAM (Special Air Mission) flights. Some remain in Navy service in 2025 after more than 35 years.
