The Gulfstream III improved on the GII with updated Rolls-Royce Spey engines, winglets, and a stretched fuselage, giving Orlando charter clients up to nineteen seats and around 4,200 nautical miles of range in a large-cabin platform that many operators have kept in service through avionics upgrades.

Why the Gulfstream III / G3 Fits Orlando
The GIII’s 4,200-nautical-mile range opens transatlantic routing from KMCO, and operators who have kept these aircraft current with avionics upgrades offer a legitimate intercontinental option at pricing well below a GIV or G450. For Orlando-to-Europe travel that doesn’t require the latest cabin, the GIII is a practical alternative.
For domestic large-group travel, the GIII’s nineteen-seat cabin covers OCCC convention groups, sports teams, and executive delegations that exceed the capacity of a Challenger 604 or 605. KORL handles the aircraft, and the FBO infrastructure at both Sheltair and Atlantic Aviation accommodates the platform.
Avionics upgrades are worth asking about on a specific GIII. Some operators have invested in EFIS cockpit upgrades and ADS-B compliance that bring the aircraft’s systems close to current standards. Others have not. We confirm the specific aircraft’s avionics status before presenting it to clients with strong currency preferences.

- FAR Part 135 charter operators for traditional private aircraft, or FAR Part 121 for airliner-size and group trips (or the foreign equivalent on international legs)
- Operator subscription to Wyvern and ARGUS reviewed where the operator participates; reports may be provided on request.
- Pilot experience and operator incident history reviewed before we recommend an aircraft.
- Fewer than 60 brokers worldwide hold Premium Wyvern Broker Member status, and Air Charter Advisors is one of them.
