The Boeing 777, also known as the Triple Seven, is an American long-range wide-body airliner. It is the world's largest twinjet and the most-built wide-body airliner. The 777 was designed to bridge the gap between the twin-engined 767 and quad-engined 747, and to offer better fuel efficiency than the latter. The fuel capacity of the 777-200 is 117,350 litres, while the 777-200ER and 777-300 have a capacity of 171,175 litres. The 777-200LR has a fuel capacity of 195,280 litres.

What You'll Learn
The 777-200ER's fuel capacity
The Boeing 777, commonly referred to as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. The 777 is the world's largest twinjet and the most-built wide-body airliner.
The B-market 777-200ER ("ER" for Extended Range") is a variant of the 777 that offers additional fuel capacity and an increased maximum takeoff weight (MTOW), enabling it to operate transoceanic routes. The 777-200ER has a maximum fuel capacity of 45,200 US gallons (171,200 litres), which, combined with its powerful 93,700 lbf (417 kN) engines, gives it an impressive range of 7,065 nautical miles (13,084 km; 8,130 mi). This range capability allows the 777-200ER to fly extended routes, such as transoceanic crossings, with ease.
The 777-200ER has been a successful aircraft for Boeing, with 422 deliveries made to 33 customers as of 2019. The aircraft's combination of fuel capacity, range, and passenger capacity has made it a versatile option for airlines operating long-haul routes. However, with increasing competition from more fuel-efficient aircraft like the Airbus A350 XWB and Boeing's own 787 series, Boeing has continued to develop improvement packages for the 777 series, including the 777X, to enhance fuel efficiency and maintain the competitiveness of the aircraft in the market.

The 777-300ER Special Freighter
The Boeing 777, commonly referred to as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. The 777 is the world's largest twinjet and the most-built wide-body airliner.
The 777-300ER SF is the first aftermarket 777 freighter conversion program, with GECAS ordering 15 aircraft with 15 options. The first 777-300ER to be converted was received by IAI in June 2020, and the first aircraft was scheduled to be delivered to launch operator Michigan-based Kalitta Air in 2023. By March 2023, IAI had completed the first flight of a 777-300ER SF, converted for AerCap, and had a backlog of over 60 orders.
The 777-300ER SF is an example of how Boeing has used 777 aircraft in research and development programs. The first such program was the Quiet Technology Demonstrator (QTD), which was run in collaboration with Rolls-Royce and General Electric to develop and validate engine intake and exhaust modifications, including chevrons used in the 737 MAX, 747-8, and 787 series.

The 777-200LR's range record
The 777-200LR Worldliner, or "LR" for Long Range, is one of the longest-range commercial airliners in the world. It entered service in 2006 and holds the world record for the longest non-stop flight by a commercial airliner. The 777-200LR was designed to connect almost any two airports in the world, though it is still subject to ETOPS restrictions.
The 777-200LR has a maximum range of 8,555 nautical miles (15,844 km; 9,845 mi) as of 2017. This range is made possible by the plane's increased maximum takeoff weight (MTOW) and three optional auxiliary fuel tanks in the rear cargo hold. The -200LR was designed for ultra-long-haul routes such as Los Angeles to Singapore.
On November 10, 2005, the first 777-200LR set a record for the longest non-stop flight of a passenger airliner. The plane flew 11,664 nautical miles (21,602 km; 13,423 mi) eastward from Hong Kong to London in 22 hours and 42 minutes. This flight surpassed the -200LR's standard design range and was logged in the Guinness World Records.
The 777-200LR is a second-generation 777 variant with extended raked wingtips and exclusive power by 110,000-115,300 lbf (489-513 kN) GE90 engines. The plane also features a redesigned main landing gear, additional structural strengthening, and wingtip extensions of 12.8 ft (3.90 m).

The 777-300's range
The Boeing 777, commonly referred to as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. The 777 is the world's largest twinjet and the most-built wide-body airliner.
The 777-300ER variant is the quietest aircraft in its class, thanks to its turbofan engines from suppliers General Electric, Rolls-Royce, and Pratt & Whitney. The 777-300ER has a range of 7,880 nautical miles (14,594 km) and can carry 359 passengers.
The 777-300ER Special Freighter has a maximum payload capacity of 101.6 tonnes (224,000 lb), a range of 4,500 nautical miles (8,300 km), and a cargo volume capacity of 28,900 cubic feet (819 cubic metres). This variant has 15% more volume than a 747-400BCF and can hold 47 standard 96 x 125-inch pallet (P6P) positions, which is 10 more than the 777F.
The 777-300X, approved by the Boeing board in March 1997, can carry 355 passengers in a tri-class layout over a range of 6,600 nautical miles (12,200 km). The 777-300X has a higher maximum take-off weight (MTOW) of 715,600 lb (324,600 kg) compared to the 777-200X.
The 777-300 series has higher fuel capacity than the 777-200, which has a fuel capacity of 117,350 litres. The 777-300ER variant, in particular, has received engine and aerodynamics improvement packages for reduced drag and weight, further increasing its range.

The 777-200's fuel capacity
The Boeing 777, also known as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. The 777-200 is the baseline model and was first delivered to United Airlines in June 1995.
The 777-200 has a fuel capacity of 117,350 litres. The 777-200ER ("ER" for Extended Range) has additional fuel capacity, with a total capacity of 171,175 litres. This increased fuel capacity provides a range of 13,084 km (7,065 nmi).
The 777-200LR Worldliner has an even greater fuel capacity of 195,280 litres, achieved through additional fuel tanks in the rear cargo hold. This variant set a world record for a commercial aircraft non-stop flight, travelling 21,601 km (11,664 nmi) from Hong Kong to London Heathrow.
The 777-200 series has improved fuel efficiency compared to other aircraft in its class, such as the quad-engine wide-body 747. This, along with its higher passenger capacity, was a key benefit of the 777-200 when it was introduced.
