The Gulfstream G650 / G650ER of Gulfstream Aerospace is a twin business aircraft . The G650 program was started in 2005 and presented to the public in 2008. The G650 is the largest and fastest business aircraft in the manufacturer's range and has one of the longest ranges in its market segment.
history
Development of the Gulfstream G650 began in 2005. On March 13, 2008, it was first presented as the successor to the Gulfstream G550 . The machine has a 28 percent larger cab than the G550, which is also 35 cm wider and 7 cm higher. The roll-out took place on September 29, 2009 at Gulfstream's headquarters in Savannah and the first flight of the machine took place on November 25, 2009 with test pilots Jake Howard and Tom Horne and flight test engineer Bill Osborne on board. On November 18, 2011, the provisional and on September 7, 2012, the final approval by the US American aviation authority FAA was granted. The first series machine was delivered to a US customer on December 20, 2012. For 2014, Gulfstream was awarded the Collier Trophy for this aircraft .

Engines
It is powered by two newly developed engines from the Rolls-Royce BR700 family with the designation BR725, which were produced in Germany . The engines are a further development of the BR710 series and produce 75.2 kN (16,900 pounds ) instead of 68.4 kN of thrust; Thanks to its lower consumption, the G650 with the engine should achieve twelve hours of flight time at Mach 0.9. The integrated FADEC engine control is responsible for improved economy in the respective flight condition; As a result, this type of aircraft achieved both a range and a speed record for business jets.

The wings with a sweep of 36 ° contain the entire fuel supply and hold up to 20,050 kg of kerosene in the tanks. The G650 is equipped with two toilets , a kitchen, a bar and various entertainment electronics as well as a satellite telephone and wireless Internet connection. In addition, the G650 has a quadruple redundant fly-by-wire control. The cabin accommodated in the oval fuselage for 13 to 16 passengers is equipped with 16 large windows measuring 71 cm × 52 cm and has a total size of 16.33 m in length, 1.95 m in height and 2.59 m in width. In addition, a cabin pressure that is higher than that of other machines - the pressure at the service ceiling corresponds to that at an altitude of 1500 meters - and improved noise insulation should ensure greater comfort.
Enhanced Vision System
The G650 aircraft are to be equipped with an addition to the head-up display called an enhanced vision system , which uses an infrared camera to show a picture of the surroundings and enables the pilots to carry out approaches up to a decision height of 100 feet (approx. 30 meters) ; In this case, however, no - expensive - approval for approaches according to CAT II is necessary, the aircraft flies instead to CAT I (normally with a decision height of 200 feet) with the reduced requirements of 100 feet and 350 meters minimum visibility. The system has been approved by EASA .
Version G650ER (Extended Range)
On May 18, 2014, at the European Business Aviation Association's annual exhibition, it was announced that Gulfstream has developed another version of the G650 with extended range. The G650ER has larger tanks in the wings that can hold up to 4,000 pounds (1,814 kg) more fuel than the G650. The maximum take-off mass was also increased by this value, so that the maximum payload remained unchanged with full tanks. With full tanks and a cruising speed of Mach 0.85, the G650ER has a maximum range of up to 13,900 km. The G650ER was approved in October 2014. At the end of March 2019, a G650ER set a new speed record for business jets. During the flight from Singapore to Tucson (Arizona) an average speed of Mach 0.85 (1007 km / h) was measured on the 15,518 km long route. Up until then, this was also the longest flight ever made by a business jet.
In July 2019, a new world record for the fastest circumnavigation of the earth was set with a G650ER. The flight lasted 46 hours, 39 minutes and 38 seconds.
Existing G650s can be upgraded to the status of the G650ER with a retrofit service bulletin. The cost of the service bulletin is approximately $ 2 million.
Incidents
On April 2, 2011, an aircraft in the G650 test fleet (N652GD) crashed immediately after taking off from Roswell International Air Center in the US state of New Mexico . All four crew members - two pilots and two engineers - were killed in the incident. The aircraft had carried out a take-off with a simulated engine failure in order to determine the length of the take-off run with minimal flap position and engine failure. After take off, the plane touched the ground with the tip of the right wing and sagged. The landing gear did not withstand the impact and the plane caught fire. The cause of the accident was an incorrect calculation of the safe take-off speed (V 2 ). By falling below the actual V 2 , the right wing stalled . The problem of unintentional taxiing had previously occurred on two other test flights. However, it had not been adequately investigated by Gulfstream, so the cause was only determined after the crash.
