Overview of the Gulfstream G450 Jet
The G450 is the final version of Gulfstream's GIV family, a line of large business jets built in Savannah, Georgia from 1985 to 2018. Its certification name is GIV-X. The FAA approved it on August 12, 2004.
Gulfstream began work on an improved GIV-SP in 2001. The G450 first flew on April 30, 2003, and production began in October 2004, replacing the G400. The last G450 was delivered on January 19, 2018, after 365 deliveries over 12 years. A reduced-fuel version was sold as the G350.
Compared with the original Gulfstream IV, the G450 has a fuselage 12 inches longer, the main entry door moved aft, upgraded engines and many systems taken from the Gulfstream V-SP family, including the forward fuselage and larger cockpit of the G550.
When a helicopter transfer makes more sense than a Gulfstream G450
A G450 is the right tool for a long flight with a group. It is the wrong tool for a short hop to the airport. In New York, BLADE offers flights between Manhattan and JFK or Newark in about 5 minutes, from $195 per seat, and a BLADE vehicle takes you from the airport heliport to your terminal. For other short trips, BLADE can arrange a helicopter charter.
Technical Specifications of the Gulfstream G450 Jet
Performance and Range
- Maximum range: 4,350 nm at Mach 0.80 (Gulfstream)
- Cruising speed: Mach 0.80 to 0.85
- Maximum speed: Mach 0.88
- Service ceiling: 45,000 ft
- Engines: two Rolls-Royce Tay 611-8C turbofans with FADEC
- Maximum takeoff weight: 74,600 lb
- Wingspan: 77 ft 10 in
Cruise Speed
The G450 cruises between Mach 0.80 and Mach 0.85. Its published maximum range is quoted at Mach 0.80. Flying faster shortens the time in the air but uses more fuel and reduces range.
Maximum Altitude
The service ceiling is 45,000 feet. That gives the crew room to climb above much of the weather when the route allows.
Range
With 4,350 nautical miles of range, the G450 can fly many long routes nonstop. Range on the day depends on passengers, bags, winds and reserves. The operator plans each trip and will tell you if a fuel stop is needed.
What types of missions is the Gulfstream G450 best suited for
The G450 suits long domestic and international trips for groups who want a large cabin. For the longest routes, a jet with more range such as the G550, which Gulfstream lists at 6,750 nautical miles, may avoid a fuel stop.
Dimensions and Capacity
The G450 is certified for up to 19 passengers, limited by emergency exit requirements. Most executive layouts seat fewer. Gulfstream's listing shows 16 passengers with 6 berths.
Passenger Capacity
Seat count and the number of seats that convert to beds vary by aircraft, so check the seat map with the operator.
Interior and Comfort Features of the Gulfstream G450 Jet
Cabin Layout and Design
The G450 is a large-cabin jet, with room for several seating areas and berths for sleeping. Owners customize interiors, so finishes and layouts vary. Ask for recent photos and the seat map of the specific aircraft.
Seating and Amenities
Ask the operator about the galley, the lavatory, the sleeping layout and catering on your specific aircraft.
Entertainment and Connectivity
Wi-Fi and entertainment systems are installed and upgraded by each owner. If you need to work in flight, confirm the system and its coverage on your route.
Choosing the right aircraft based on distance and time sensitivity
Start with distance and group size. A G450 fits a large group on a long flight. A smaller jet fits shorter trips with fewer people. A helicopter fits the short trip to the airport. BLADE arranges private jet charters with licensed operators, so you can compare aircraft for your route.
Safety and Security Features of the Gulfstream G450 Jet
Advanced Avionics and Systems
The G450 uses Gulfstream's PlaneView cockpit, with four 14-inch liquid crystal displays and a head-up display. It does not have fly-by-wire flight controls.
Enhanced Flight Deck
The G450 shares the larger cockpit and forward fuselage of the G550. It also uses Gulfstream V-SP systems such as the Honeywell flight deck display suite, electrical power generation, cabin pressurization and temperature control.
Emergency and Safety Enhancements.
Gulfstream added a flight control hard-over protection system and redesigned main landing gear wheels and brakes. For a charter, the operator is responsible for the crew, maintenance and compliance with FAA rules, so ask who operates your flight.
