The Gulfstream G650's fuel burn rate is 480 gallons per hour or 3100 pounds per hour
The Gulfstream G650 is a luxurious, ultra-long-distance, super-fast business jet. It is powered by two Rolls-Royce BR725 turbofan engines, which together consume 480 gallons of fuel per hour, or 3100 pounds per hour. This fuel burn rate is specifically applicable when flying at FL450.
The G650's fuel burn rate is influenced by various factors, including speed, altitude, and distance travelled. For instance, when flying at Mach 0.85, the aircraft burns 2400 pounds or 1100 kilograms per hour. At this speed, the G650 can fly a distance of 5,555 kilometres and burn a total of 16,000 pounds or 7,257 kilograms of fuel.
The Gulfstream G650's fuel efficiency is further enhanced by its advanced wing design. Its wings have a sweep of 36 degrees, greater than previous Gulfstream aircraft, and do not feature leading-edge high-lift devices. This wing design contributes to the aircraft's exceptional performance and range.
Additionally, the G650 is equipped with a fuel quantity monitoring system (FQMS) that helps prevent fuel stratification issues. This system, built by Zodiac subsidiary Intertechnique, uses a distributed architecture that ensures the accuracy of fuel quantity readings. The G650 also features larger diameter fuel tubing and electronically controlled refuelling, resulting in faster refuelling and fuel removal processes.
The G650's fuel burn rate of 480 gallons per hour, or 3100 pounds per hour, contributes to its impressive range and performance capabilities, making it a popular choice for long-distance travel.

The jet's range is 7,000 nautical miles
The Gulfstream G650 is a large business jet produced by the American company Gulfstream Aerospace. The G650's range is 7,000 nautical miles, allowing it to fly long distances without refuelling. This range is made possible by the jet's efficient fuel usage and powerful engines.
The G650 typically consumes 480 gallons or 3,100 pounds of fuel per hour at FL450, with a maximum fuel burn of 489 gallons per hour. However, during the first hour of flight, which includes launch, second-stage climb, and ascent to altitude, the fuel burn is higher, at approximately 1,100 gallons.
The Gulfstream G650 is powered by two Rolls-Royce BR725 turbofan engines, which produce a combined total of 33,800 pounds of thrust at takeoff. These engines are an upgraded version of the BR710, featuring a larger fan diameter and improved bypass ratio, resulting in higher fuel efficiency.
The G650's range of 7,000 nautical miles allows it to fly non-stop on many long-haul routes. For example, it can fly from Hong Kong to Teterboro, New Jersey, a distance of 7,494 nautical miles, or from Los Angeles to Melbourne, Australia, without refuelling.
The jet's range and fuel efficiency are further enhanced by its wing design, which features a sweep of 36 degrees and no leading-edge high-lift devices. This wing design contributes to the G650's superior performance and efficiency compared to previous Gulfstream models.
In summary, the Gulfstream G650's range of 7,000 nautical miles is a result of its efficient fuel usage, powerful engines, and advanced wing design. This range enables the jet to fly non-stop on many long-haul routes, making it a capable and versatile choice for long-distance travel.

The G650 uses two Rolls Royce BR725 engines
The Gulfstream G650 is a large business jet produced by the American company Gulfstream Aerospace. The aircraft is powered by two Rolls-Royce BR725 turbofan engines, mounted on the rear fuselage. Each engine offers 16,900 pounds of thrust and they use a combined 485 gallons of fuel per hour. The G650 has a range of 6,912 nautical miles when operating under NBAA IFR with 8 passengers and available fuel.
The BR725 engine is a variant of the G550's BR710 engine, featuring a larger 1.27m-diameter fan with a 24-blade swept-design and a solid titanium case. The BR725 provides 16,100 pounds of take-off thrust and offers an additional 12.6% thrust during climb. The Gulfstream G650's fuel quantity monitoring system (FQMS) is built by Zodiac subsidiary, Intertechnique, and features a distributed architecture that prevents a single failure from masking fuel quantity.
The G650 has a maximum speed of Mach 0.925 and can carry 19 passengers or sleep 10. The aircraft's first flight took place in November 2009 and it received FAA certification in September 2012. The latest model costs $75 million, while a used 2015 model averages between $60 and $65 million.
The G650 is known for its ultra-long-distance capabilities and luxurious interior. It is a popular choice for corporate pilots and has been used to fly hundreds of the world's rich and famous to their destinations.
