Can all planes dump fuel?

Not all planes are equipped with this sophisticated system, however. FAA spokesperson Alison Duquette says that narrow-body planes, like the Airbus A320 or the Boeing 757, aren't built with fuel dumping abilities. But larger, wide-body planes, like the Boeing 777 and 747, which have added tanks, can dump fuel.

Since most twin jet airliners can meet these requirements, most aircraft of this type such as the Boeing 737 (all models), the DC-9/MD80/Boeing 717, the A320 family and various regional jet (RJ) aircraft do not have fuel dump systems installed.

Airlines find that fuel dumping can actually be cheaper than not dumping in certain circumstances. But it's not something pilots do on a routine basis. We spoke with Alison Duquette, spokesperson for the Federal Aviation Administration (FAA), who assured us that it doesn't happen very often.

For some aircraft types, the maximum allowable landing weight is substantially less than the aircraft's take-off weight. The Boeing 747, 777, and Airbus A380s are examples, and these three aircraft types do have fuel dumping capabilities.

On the other hand, Federal Aviation Regulations require certain aircraft, like the Boeing 747 for instance, to have a fuel jettison system. The same holds true for Airbus aircraft; the Airbus A340 and A380 can dump fuel, while the A320 cannot. All Boeing 747 aircraft have a fuel jettison system.

In the event of an emergency requiring a return to the departure airport, the aircraft circles nearby in order to consume fuel to get down to within the maximum structural landing weight limit, or, if the situation demands, simply land overweight without delay.

When an airplane experiences less drag, it consumes less fuel. This relationship between speed and fuel consumption means that flying at a slightly slower speed can result in significant fuel savings for airlines, which in turn can lower operating costs and potentially reduce ticket prices for passengers.

Larger planes like the Boeing 747, on the other hand, have fuel jettison systems. If the aircraft tried to land without dumping the fuel first, it is considered an overweight landing attempt and could place immense stress on the airframe. It could also increase the risk of fire and fuel leaking onto the tarmac.

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.

Can a wide body airliner land with a full fuel tank? Yes! But it is safer to land an aircraft below its published MLW.

MORE DETAILS

The maximum landing weight (MLW) is the maximum aircraft gross weight due to design or operational limitations at which an aircraft is permitted to land. The MLW is set in order to ensure safe landings; if an aircraft weighs too heavy during touchdown, it may suffer structural damage or even break apart upon landing.

Over a certain altitude it is always considered safe to dump fuel. The high speed of the airplane means the fuel is spread very thin and will evaporate before it hits the ground. Accidents do of course happen where it is not possible to safely dump fuel and they end up dumping over populated areas.

Also, not all planes have the capability of dumping fuel. But big ones like the 747, 787, or A380 can release it from their wingtips.
