The B-market 777-200ER ("ER" for Extended Range), originally known as the 777-200IGW (increased gross weight), has additional fuel capacity and an increased MTOW enabling transoceanic routes. [64] With a 658,000 lb (298 t) MTOW and 93,700 lbf (417 kN) engines, it has a 7,065 nmi (13,084 km; 8,130 mi) range with 301 passenger seats in a three ...
With a fuel fraction of nearly 85%, the GlobalFlyer could carry 5 times its weight in fuel.. In aerospace engineering, an aircraft's fuel fraction, fuel weight fraction, [1] or a spacecraft's propellant fraction, is the weight of the fuel or propellant divided by the gross take-off weight of the craft (including propellant): [2]
It is possible to reduce the chance of fuel tank explosions by a fuel tank inerting system or fire fighting foam in the tanks. [5] The Boeing 737, for example, has two systems that reduce the chance of a fuel tank ignition. One shuts off fuel pumps when fuel output pressure is low, to prevent them from heating (since they rely on the fuel ...

The most fuel-efficient airline was Norwegian Air Shuttle with 44 pax-km/L (2.27 L/100 km [104 mpg ‑US] per passenger), thanks to its fuel-efficient Boeing 787-8, a high 85% passenger load factor and a high density of 1.36 seat/m 2 due to a low 9% premium seating.
The aircraft involved was a Boeing 777-236ER, registered as G-YMMM, with serial number 30314 and line number 342. It was built and delivered to British Airways in 2001 and powered by two Rolls-Royce Trent 895-17 engines [10] and had a seating capacity of 233 passengers.
The Boeing 777X is the latest series of the long-range, wide-body, twin-engine jetliners in the Boeing 777 family from Boeing Commercial Airplanes. The changes for 777X include General Electric GE9X engines, composite wings with folding wingtips , greater cabin width and seating capacity, and technologies from the Boeing 787 .
[1] [5] The aircraft, which became the Boeing 777, filled a crucial size and range gap in Boeing's commercial airliner lineup, offering greater passenger capacity than the twin-engine Boeing 767 and improved operating efficiency compared to the quad-engine wide-body Boeing 747. In October 1990, United Airlines placed the first order for the 777 ...
