The Gulfstream G500 ( type certification designation GVII-G500) is a twin-engine, long-haul business jet from the US manufacturer Gulfstream Aerospace . A variant that is slightly larger in overall dimensions is called G600 (GVII-G600). Gulfstream first publicly unveiled the G500 on October 14, 2014 at Savannah Airport as the next generation of Gulfstream aircraft based on technology from the Gulfstream G650 and G650ER. After production of the G450 was discontinued in early 2018, the G500 is supposed to fill the gap between the G280 and the G650 .
history
development
Work on the G500 and G600 began in 2008 under the project name P42. Special consideration was given to the more than 200 suggestions for improvement from the Gulfstream operators, which are part of the Advanced Technology Customer Advisory Team (ATCAT).
testing
The test was carried out with four aircraft. A fifth machine serves as a demonstration aircraft z. B. at airshows. While these aircraft had six windows on each side, all copies from the seventh machine (first customer aircraft), like the G600, have seven windows each.

|---|---|---|---|---|---|
| Work number | 72001 | 72002 | 72003 | 72004 | 72005 |
| Mark | N500GA | N502GS | N503G | N504GS | N505GD |
| First flight | May 18, 2015 | 20th November 2015 | 20th November 2015 | 20th February 2016 | 5th August 2016 |
Test and approval operations have also been carried out for the G600 with a total of five machines since December 2016. At the Business Aviation Convention in Las Vegas in October 2017, Gulfstream announced that significantly better values than originally guaranteed could be flown, especially for the range. At a cruising speed of Mach 0.9, the range was increased by 550 km (G600) to 1100 km (G500).
After more than 5000 flight hours, the G500 received type certification from the FAA in July 2018 and on the same day also certification for the start of series production.
Series production
The first delivery of a G500 series machine took place on September 27, 2018, when Franklin Mountain Assets in El Paso (Texas) received the serial number 72010. The first international customer was Qatar Executive Airways , which took over two G500s at the end of December 2018. So far, as of May 2019, a total of 58 G500 and 19 G600 have been delivered.
construction
Wings and engines
The G500 / G600 has completely redesigned wings, which are also being built by Gulfstream for the first time. These have a supercritical profile and a sweep of 36 ° in 25% of the wing depth (t / 4 line). There are only simple Fowler flaps on the trailing edge and no slats to aid buoyancy in order to keep the number of moving parts low.
The propulsion system consists of two jet engines from the Pratt & Whitney Canada PW800 series. G500 uses two PW-814GAs with a thrust of 67.4 kN each, while the G600 uses two PW-815GAs with 69.7 kN each.

Members of the ATCAT consortium suggested the use of an enlarged fuselage with the cross-section of the G650, but Gulfstream found this impracticable because of the weight and drag disadvantages. An oval cross-section was also rejected. Compared to the G450 and G550, the new fuselage is 52 mm higher in height; the cabin is 178 mm wider and the floor area 203 mm wider. The passenger cabin is 2.13 m wide, 1.88 m high and can accommodate up to 18 people. The cabin pressure is always kept at a value that corresponds to an altitude between 3000 ft at FL 410 and 4850 ft at FL 510. The area of the cabin window has been increased by 16% compared to the G450 / G550.
Avionics

The G500 and G600 have a newly developed Symmetry Flight Deck with active-control side-sticks from Honeywell . The sidesticks are electronically coupled so that the copilot can see and feel the movements of the pilot's sidestick. The main equipment of the cockpit are four 12 × 8 inch screens and ten touch-screen control units . In addition, the Enhanced Vision System (EVS), which has been in use at Gulfstream since 2004 and is based on the images from an externally mounted infrared camera, is in a third generation. EVS supports the pilot on the ground and on the final approach.
The flight control is carried out via a three-axis fly-by-wire system. This ensures, among other things, protection against exceeding the permissible flight parameters ( flight envelope protection ).
Materials / construction
The fuselage, wing and vertical tail fin are made of various metal alloys and a small amount of steel. The tailplane fin, rudder, spoiler, winglets, the cladding of the fuselage-wing transition , the cabin floor and pressure bulkheads are made of composite materials .
The G500 and G600 are manufactured in two newly built 37,100 m 2 manufacturing facilities in Savannah. One building is used for the construction of the wings and tail unit, while in the second the fuselage is produced and final assembly takes place.
