Boeing 777 Spotting Guide


The Boeing 777 is a family of long-range wide-body twin-engine jet airliners developed and manufactured by Boeing Commercial Airplanes.

It is the world's largest twinjet and has a typical seating capacity for 314 to 451 passengers, with a range of 5,235 to 9,500 nautical miles (9,695 to 17,594 km).

Commonly referred to as the "Triple Seven", its distinguishing features include the largest-diameter turbofan engines of any aircraft, six wheels on each main landing gear, fully circular fuselage cross-section, and a blade-shaped, sawed-off tail cone.

Background and Development

As Boeing's first fly-by-wire airliner, the 777 has computer-mediated controls. It was also the first commercial aircraft to be designed entirely with computer-aided design.

The 777 first entered commercial service with United Airlines on June 7, 1995. It has received more orders than any other wide-body airliner; as of July of 2016, 60 customers had placed orders for 1,893 aircraft of all variants, with 1,417 delivered.

The 777, sometimes called the "Worldliner", is currently produced in two fuselage lengths:

  • The original 777-200 variant entered commercial service in 1995, followed by the extended-range 777-200ER in 1997.
  • The stretched 777-300, which is 33.25 ft (10.1 m) longer, followed in 1998. Also, the 777-300ER has been an extremely popular model with world airlines.

Boeing announced the Boeing 777-8X and 777-9X in 2013 with improvements on the aircraft using 787 technology, composite wings and improved GE9X engines.
