Why the Gulfstream IV / IV-SP / G400 Fits Colorado

With 4,220 nautical miles of published range, it covers trips from Denver to destinations such as San Francisco, Washington and Honolulu, allowing for reserves and routing. Aspen’s airport will close to all aircraft from April 4th to November 19th, 2027 for runway reconstruction, so a trip to Aspen in that window will be planned through another airport, such as Eagle County or Rifle.

Centennial caps aircraft at 70,000 lb maximum takeoff weight, or 75,000 lb for Stage III aircraft, so heavier aircraft leave from Denver International, Rocky Mountain Metropolitan, Colorado Springs or Colorado Air and Space Port. At Colorado’s elevations, whether the aircraft can use a particular airport on your date is the operator’s call for that aircraft, its weight and the day’s conditions, and your advisor will confirm it before anything is booked.

How Colorado Clients Use the Gulfstream IV / IV-SP / G400

Heavy jets carry larger Colorado groups a long way, such as a family to Mexico for the holidays, a company team to either coast, or a party to Europe on some routes. Most aircraft in this class seat between ten and sixteen people, with cabins built for long days in the air.

Tell us the route, how many people are flying and what they are bringing, skis and golf bags included, and your advisor will say whether this aircraft suits the trip or suggest one that suits it better.

Vetting Behind Every Trip

Every operator, aircraft, and crew goes through our internal due diligence before we present any options. Our internal standards meet or exceed what the FAA requires:

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.
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.
