There are four main fuel tanks in the wings, a tail plane tank, a center wing tank, and reserve fuel tanks in the outer wing sections. The maximum fuel capacity is 216,846 L (57,284 gal.).

Fuel Storage in AirplanesBelieve it or not, an airplane's wings often contain a majority of the fuel the aircraft will use. Some planes also possess fuel tanks inside the aircraft's body; however, there are several benefits to placing fuel in the wings of an airplane.
How far can a Boeing 747 fly without refueling? A: This depends on the size of the plane, its efficiency, and how fast it's flying. A modern Boeing 747 can fly about 15,000 km (9,500 miles) when it's flying at 900 kmh (550 mph).
Fuel dumping (or a fuel jettison) is a procedure used by aircraft in certain emergency situations before a return to the airport shortly after takeoff, or before landing short of the intended destination (emergency landing) to reduce the aircraft's weight.
As a rule of thumb for the Boeing 747, pilots either quote dump rates ranging within 1–2 tons per minute or reference a thumb formula of dump time = (dump weight / 2) + 5 in minutes.
But it's much more than a time waste. It's also a big source of carbon emissions. The average taxi time in the U.S. is between 16 and 27 minutes, which accounts for about 5% of a flight's fuel consumption. A Boeing 747, for example, uses 1 ton of fuel during a 15-minute taxi.
A: The tracks across the Atlantic are determined daily to take into account the meteorological conditions of the moment. If there are strong winds, the eastbound tracks will be farther north to take advantage of them, while the westbound flights will be routed south to avoid the headwinds.
A pilot will choose to dump fuel only on very rare occasions. Brickhouse: Unless you have a medical emergency on board, someone is dying, you don't really have time to fly around and burn fuel. So, in that case that's when you would dump fuel so that you can lose weight quickly.
Therefore, Boeing's general recommendation is to jettison fuel above 5,000 to 6,000 feet whenever possible, although there is no restriction on jettisoning at lower altitudes if considered necessary by the flight crew.
The most common reason is that there are no airstrips or airports on many of the small islands, so if a plane had to make an emergency landing, it would be difficult to find a place to land. Additionally, the Pacific Ocean is vast and remote, so if a plane were to go down, it would be very difficult to find.
Qantas 747-400 City of Canberra (VH-OJA) flew from London to Sydney non-stop during its 1989 promotional flight, flying 17,000 kilometers in about 20 hours.
A member of the same Boeing 747 family, the 747-400 is a behemoth that can catapult 416 passengers across the world with a maximum speed of Mach 0.855 (656 mph). With a range of up to 7,225 nautical miles, it's most commonly used for busy long-haul routes with high demand.
