The Gulfstream IV (or GIV or G4) and derivatives are a family of private jet aircraft produced by Gulfstream Aerospace, a General Dynamics company based in Savannah, Georgia, United States. The G-IV ceased production in 2003.
Design and development
Gulfstream began work on the GIV in 1983. The first GIV made its maiden flight on September 19, 1985. The model received type certification from the FAA in April 1987.[2] The G-IV entered into service with serial number 1000 in 1987 and was upgraded to the special purpose GIV-SP version at serial number 1214 in 1993. It was later redesignated G400 at serial number 1500.[3]

A shorter range variant was created based on the GIV and given the G300 designation in 2002.[2] The G400 has a large cabin, long range of 4,350 nautical miles (8,060 km) and the same comfort and design that characterize the G series. Typical cruise height and speed are 45,000 ft and Mach 0.88. Earlier models were fitted with Honeywell's SPZ 8000 Avionics package. The SPZ 8400 Avionics Package was an option, becoming standard on later models. It costs about $15 million at 2009 prices.[3]
In 2001 Gulfstream began work an improved version of the GIV-SP, originally designated GIV-X. It was later renamed G450. The G450 is lengthened 1 ft (0.305 m) over the G400 and shares the forward fuselage and larger cockpit of the G550. Production of the G450 began in October 2004, replacing the G400. The G450 has better performance and comes with the PlaneView cockpit with four 14 in (355 mm) liquid crystal displays and a Head up display (HUD). The shorter range G350 version of the G450 was developed and received certification in 2004.[4][5]
Operational history
The National Oceanic and Atmospheric Administration (NOAA) operates a GIV-SP modified to fly scientists and crew members at 45,000 feet around tropical cyclones. The aircraft was modified to drop instruments called "dropsondes" to measure windspeed, barometric pressure, humidity, and temperature as they fall to the surface of the ocean. By sampling the cyclone with these dropsondes over a 4,000 mile track around the storm, the forecasters at NOAA's National Hurricane Center and Hurricane Research Division can better predict where the hurricane will be "steered" by the upper level winds. They also predict wind shear that will either increase or decrease a hurricane's strength. The GIV-SP is suited for this mission since it is fast, and can fly long distances with ample cabin space for the crew and instruments.[6]
In June 1987 a Gulfstream IV set 22 world records in its class in flying west around the world in 45 hr 25 min. The next year another GIV set 11 world records flying east around the world.[7] In 1990, Gulfstream CEO Allen E. Paulson and a Gulfstream flight crew set 35 international records for around-the-world flight in a GIV.[citation needed]
Variants
C-20F/G/H/J military variants
The U.S. military variant of the IV, designated C-20F/G/H/J Gulfstream IV in Department of Defense service.[8] The C-20F is a GIV model operated by the U.S. Army in a command/executive transport role. The C-20G aircraft[9] may be configured for cargo operations, 26 passenger operations or combinations of the two. With passengers seats removed, it may be configured as three pallets with no passengers or two pallets and eight passengers or one pallet and fourteen passengers. With full seating, the aircraft is capable of accommodating up to twenty-six passengers and a crew of four. A hydraulically-operated cargo door is installed on the starboard side of the aircraft, and a ball roller cargo floor is capable of accommodating palletized cargo.
The C-20G variant is operated by Fleet Logistics Support Squadron Four Eight (VR-48) and Marine Air Support Detachment (MASD) at Naval Air Facility, Andrews Air Force Base, Washington, DC and at Fleet Logistics Support Wing Detachment, Marine Corps Base Hawaii. The C-20H is a GIV-SP model operated by the U.S. Air Force in a command/executive transport role. The C-20J is a GIV-SP model operated by the U.S. Army in a command/executive transport role.
G350/G450
The G450 is an improved version of the GIV-SP/G400 using technologies from the G500/G550 (an upgrade to the GV). It has a "PlaneView" cockpit with 4 Honeywell 21 EFIS screens, and a Gulfstream-designed cursor control system. It also has the "Enhanced Vision System" (EVS), an infrared camera that displays an image of the view in front of the camera on a head up display. EVS permits the aircraft to land in lower-visibility instrument meteorological conditions than a non-EVS-equipped aircraft.
The G350 is the short-range version of the G450. It has the same exterior appearance as G450, and includes the PlaneView cockpit, but does not have EVS as standard equipment, which is available as an option.
