2004 – 2017

Key Facts

  • The Gulfstream G450 is a large jet manufactured by Gulfstream between 2004 and 2017.
  • The Gulfstream G450 is powered by two Rolls-Royce TAY 611-8C engines, resulting in an hourly fuel burn of 465 Gallons per Hour.
  • Capable of cruising at up to 500 knots, the Gulfstream G450 can fly non-stop for up to 4350 nautical miles.
  • The aircraft can carry up to 16 passengers.
  • The Gulfstream G450 has an estimated hourly charter price of $7500, with a new list price of $43 million at the time of manufacture.

Overview & History

The Gulfstream G450 is a direct descendent of the Gulfstream G400/GIV-SP series. It comes with upgraded engines (Rolls-Royce Tay 611-8C) with FADEC, and redesigned thrust reverser, nacelle, and pylon that, coupled with aerodynamic improvements, increase range and payload.

As of November 2016, 33% of the Gulfstream G450 aircraft were purchased pre-owned by their current owners, the other 67% new. Currently, 8.5% are for sale with the majority of those (76%) under an exclusive broker agreement. When for sale, the average time on the market is 244 days.

Flight-testing of the Gulfstream G450 started in April 2003 and FAA certification was completed in August 2004. A total of 342 Gulfstream G450 aircraft have been manufactured, all are still in operation today. Production of the G450 will end in early 2018 as Gulfstream transitions production to its new G500.

Gulfstream G450 Performance

The Gulfstream 450’s Rolls-Royce Tay Mk 611-8C engines are built around the high-pressure engine core of the SpeyRB.183-555, which has successfully documented thousands of hours of flight time in various other commercial and private jets.

The Rolls-Royce Tay engine, however, gets 2,600 pounds more thrust on takeoff than the Spey.

The Tay engines produce 13,850 pounds of thrust each, allowing a sea-level takeoff in 5,450 feet. At an altitude of 5,000 feet, the runway requirement is 8,030 feet.

The engines easily meet both FAR part 36 phase III noise requirements, producing 79.1EPNdBon takeoff, and SFAR part 27 emissions limits.

Oil consumption and vibration levels are reportedly low as well. The Gulfstream 450 can climb to 41,000 feet in twenty-three minutes.

After more than 800 hours of wind tunnel testing and aerodynamic improvements, the Gulfstream 450 is able to cruise at .85 Mach (476 knots) while at a cruise altitude of 41,000 feet. The Gulfstream 450’s flight envelope extends up to 45,000 feet.

The cabin is rated to 9.5 psi, allowing the G450 to maintain a sea-level cabin at 22,000 feet. The maximum range (while traveling at .80 Mach with eight passengers and three crew members) is 5,000 miles (4,350 nautical miles).

Gulfstream G450 Interior

Between fourteen and eighteen passengers should ride comfortably in the Gulfstream 450s 1,525 cubic foot cabin.

Passengers can easily stand in the 6.2 foot high cabin and will enjoy the 7.3 foot width and 45.1 feet in length (an 18-inch increase from the G-III).

The 169 cubic feet of baggage space is accessible in flight. Two full-length closets for coat storage are located inside the two fully enclosed lavatories.

There are plenty of cabin features that should make transcontinental and transoceanic flights enjoyable.

To begin with, the full-sized galley comes fully equipped with everything needed for hot and cold food preparation: a high-temperature oven, microwave, and full-sized sink with hot and cold water, cooled storage, two coffee makers, and an optional espresso machine.

There is even fitted storage space for the dinner service (including crystal and cutlery) custom-made for Gulfstream’s private jets.

Standard and optional electronic offerings include a CD, VHS, and DVD player, two LCD screens, individual headphones at each seat (for the cabin audio system), a fax machine, and satellite phones.

Additional features such as power plugs, work tables, and a LAN connection are included as well.

Electronics, lighting, and the two-zone temperature control system can be controlled from several different locations in the cabin.

Cockpit

The PlaneView cockpit has four large liquid crystal flight displays, a Gulfstream enhanced vision system (EVS) with a Honeywell HUD 2020 head-up display, and a cursor control device.

The EVS, developed by Gulfstream and Kollsman, is the first vision system of its type to be certified by the Federal Aviation Administration.

The vision system gives the pilot a heightened level of situational awareness and allows greater safety.

In January 2008, the FAA certified the Gulfstream synthetic vision-primary flight display (SV-PFD) system and the Gulfstream / Kollsman second-generation EVS II for the G450.

SV-PFD displays three-dimensional, color terrain images from the Honeywell enhanced ground proximity warning system (EGPWS). EVS II is 10kg lighter with four times the computational power and memory of the previous EVS.

The aircraft is fitted with a Honeywell Primus Epic avionics suite. The avionics systems are installed forward of the cabin door.

Gulfstream G450 Charter Cost

The cost to charter this jet starts at around $9,900 an hour.

Hourly charter rates do not include all taxes, fuel, and other fees.

Charter costs will vary based on year of make/model, schedule, routing, passenger & baggage totals, and other factors.

Purchase Price

The acquisition cost for this jet typically ranges from $40 million.

The price of a jet depends on the production year; it can also go above the given range if the production is new.

It will cost buyers around $2 million per year which includes fuel, crew members, and maintenance, etc. The price of a pre-owned aircraft can be within $30 million.
