First flight

The most successful large widebody ever, with over 830 built, powered by the GE90-115B, the most powerful jet engine in regular service until the GE9X. Emirates operates more than 100 of them. It effectively killed the four-engine airliner by matching 747 capacity with twinjet economics.

The story of the Boeing 777-300ER

Boeing launched the 777-300ER in February 2000. It is a heavier, longer-range development of the 777-300, built to replace the 747-400 on long-haul trunk routes. Airlines wanted 747 space without 747 fuel bills, and Boeing answered with a twinjet of almost the same size. It first flew on February 24, 2003, and Air France began service in May 2004. The type reshaped long-haul flying within a decade.

Only one engine is offered, the General Electric GE90-115B, the most powerful commercial jet engine ever approved. Its fan is wider than a 737 fuselage, which makes the aircraft unmistakable. The result matched 747-class capacity with twinjet economics, burning roughly a fifth less fuel per seat than the jumbo it displaced. The market responded fast. Having only a single engine option kept costs and testing down.

More than 830 were delivered, making it the best-selling widebody version of its generation. Emirates alone has flown well over 100, and Cathay Pacific, Air France, Qatar Airways, ANA and Singapore Airlines built large fleets. It ended passenger 747 production and pushed the A340 out of the market. Many early airframes are now moving to freighter conversion. Production has now wound down in favor of the 777-9.

Design and engineering

Two GE90-115B turbofans, each rated at 115,300 pounds of thrust, hang on a strengthened wing whose raked tips stretch the span to 64.8 meters. The 73.9-meter fuselage seats about 365 to 400 people, and ten-abreast economy is now common. It is one of the largest twinjets ever flown.

A semi-levered main gear lets the aircraft pivot over its rear axle during rotation, which shortens takeoffs and guards against tail strikes. The fly-by-wire flight deck is common to all 777s, and many airlines pair it with the 787 in mixed-fleet flying.

How to recognise the B77W in the wild

A very long twinjet with two colossal GE90 engines, six-wheel main gear bogies, raked wingtips and a flattened blade-shaped tailcone; its sheer fuselage length distinguishes it from the stubbier 777-200 models. More tells in how to identify any aircraft overhead.

Facts about the Boeing 777-300ER

  • Each GE90-115B engine produces more thrust than all four engines of an early 707 combined.
  • Emirates has been the largest 777-300ER operator in the world, at times fielding a fleet of well over 100.
  • The -300ER's semi-levered main landing gear pivots so the aircraft can rotate over its rear wheels, easing tailstrike risk on its 73.9-meter fuselage.
  • More than 830 777-300ERs were delivered, making it the best-selling widebody variant of its generation.
