Gulfstream G450

G450 Overview

Gulfstream G450

Gulfstream G450

The Gulfstream G450® is not only the best large-cabin, long-range business jet in its class, it’s also a direct descendent of the storied GIV®-series aircraft, the best-selling business jet in the world. By the time production of the GIV-series ceased in 2002, Gulfstream had turned out over 500 of these world-class airplanes.

The G450 is a complete upgrade of what was an outstanding business jet to begin with. It can reach a maximum operating speed of Mach 0.88 and carry a management team of eight up to 4,350 nautical miles(8,056 km) at its normal cruise speed of Mach 0.80. With its intercontinental range, the G450 easily links Dallas with Paris. High altitudes do not faze this aircraft. A G450 departed the high-altitude Centennial Airport in Denver and touched down slightly more than seven hours later at Honolulu Airport on Oahu. The flight set a new city-pair speed record.

The G450′s cockpit bristles with the same advanced technology found on all other large cabin Gulfstream aircraft. The G450′s PlaneView® cockpit is considered to be the most advanced flight deck in business aviation. The airplane’s avionics suite presents critical flight status information on 14-inch(36 cm) liquid crystal display screens arranged in a landscape format. Gulfstream’s Enhanced Vision System™, a standard feature, enhances situational awareness significantly by presenting pilots with a clear picture of runway markings, taxiways and the surrounding landscape at night or in deteriorating weather conditions. Gulfstream also offers the Synthetic Vision – Primary Flight Display as an option increasing the level of safety and situational awareness even in zero visibility conditions.

G450 operators may choose from six Select Interior Configurations to personalize their cabin. Individual cabin designs will accommodate up to 16 passengers comfortably with berthing for six. Whatever the configuration, G450 passengers will appreciate the abundant sunshine streaming through Gulfstream’s signature oval windows, the 100 percent fresh air and the advanced soundproofing that envelops the living environment in new levels of quiet.

The inherent value of the G450 is evident in its GIV lineage, its PlaneView cockpit and its dispatch reliability rate, which is greater than 99.8 percent. Like all members of the Gulfstream fleet, the G450 is sustained by Gulfstream’s vast, worldwide product-support network. More than 3,000 trained professionals stationed at strategically located service centers, authorized warranty centers and line-service facilities around the world stand ready to meet the needs of the G450 fleet.

The same Gulfstream team that won the 2003 Collier Trophy, the most prestigious award in aviation today, also developed the G450. Whether you cross a continent or an ocean, the G450 will strive to exceed your expectations.

G450 Performance

You might say the Gulfstream G450® large-cabin, long-range business jet comes from good stock. It can trace its heritage back to the Gulfstream GIV®, the GIV-SP® and the G400®. The GIV series, introduced in 1986, set new standards in business aviation. It was the best-selling long-range, large-cabin business jet in the world. Longtime Gulfstream operators still speak fondly of that airplane and its succeeding generations.

Today’s G450, introduced in 2003, is an entire upgrade of what was then an outstanding business jet. It can transport eight passengers and a crew of three up to 4,350 nautical miles (8,056 km) at a normal cruise speed of Mach 0.80. It can attain a maximum operating speed of Mach 0.88 and climb to an initial cruise altitude of 41,000 feet (12,497 m) in only 20 minutes. As the trip progresses, the G450 can easily step up to a maximum cruise altitude of 45,000 feet (13,716 m).

With its intercontinental range, the G450 spans oceans and continents. Think Dallas to Paris or Honolulu to Denver.

Each of its upgraded Rolls-Royce Tay Mk 611-8C engines produces 13,850 pounds (61.6 kN) of thrust. This thrust provides excellent takeoff performance with improved capability from demanding high elevation airports on hot days. Yet when you combine this unbridled power with aerodynamic and material improvements, the G450 displays flight and performance characteristics that provide greater fuel efficiency and lower operating costs than the previous GIV family of aircraft.

Gulfstream’s engineering and technological advances extend to the G450 as well. The aircraft’s PlaneView™ cockpit, for instance, features the most advanced avionics suite in the industry, now supplemented by Gulfstream’sEnhanced Vision System II™ and optional SV-PFD™. Combine EVS with the Heads-Up display and the optional SV-PFD and pilots can experience an unprecedented level of situational awareness.

Exceptional performance, today’s advanced avionics and a heritage of engineering excellence that dates back over two decades. You wouldn’t think it could get any better.

G450 Technology

Here’s a formula for success: Take a business jet with a true pedigree, a descendent of the famous Gulfstream GIV® series and equip it with the most-advanced flight deck in business aviation. Now you have a Gulfstream G450® large-cabin, long-range business jet, an airplane that boasts virtually every major technological advance Gulfstream has made over the past two decades.

Upgraded with aerodynamic and system improvements and equipped with Rolls-Royce Tay Mk 611-8C engines, today’s G450 offers business travelers a choice of domestic or transcontinental destinations.

With its state of the art display technology, standard cursor control devices, its open architecture and its Interactive Navigation (I-Nav) management system, the PlaneView® cockpit is the most advanced flight deck in business aviation today. Fourteen-inch liquid crystal display screens provide pilots with all the system status flight information they need in landscape format. All navigation and system displays are placed in familiar locations.

Gulfstream’s Enhanced Vision System II™, a standard feature in the PlaneView cockpit, presents a clear picture of runway markings, taxiways, other aircraft and the surrounding landscape at night or in deteriorating weather conditions. The optional SV-PFD takes it one step further by displaying digitized real time terrain information on the pilot’s primary display. The net effect is to provide the flight crew with a level of situational awareness never before available.

Gulfstream’s technological achievements aren’t confined to the cockpit. They can also be found in the airplane’s spacious and comfortable cabin. Today’s business travelers can maintain their productivity by accessing the G450′s wireless local area network (LAN) or talking with clients via the satellite communications system (SATCOM), both of which are standard cabin features. As an option, G450 operators can select Gulfstream’s Broad Band Multi Link, which provides significantly faster Internet connections than single, dual or quad-channel systems.

As engineers at Gulfstream’s research and development laboratories continue to develop innovative components and systems, the PlaneView cockpit’s open architecture will continue to accommodate them. We believe there’s always room for improvement, especially when it involves the safety of your airplane.
