Do planes dump fuel in an emergency?

The manufacturers consider this in their design of an aircraft, so by the time a plane reaches its destination, it'll be light enough to land safely. Sometimes, however, in an emergency situation, a plane might be forced to land earlier than expected. And that's when fuel dumping comes in.

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.

Area and flight level Specific areas have been designated where fuel dumping is allowed to avoid damage or harm where the fuel may drop; generally speaking, this is above seas or unpopulated areas above land.

A plane like a Boeing 747 uses approximately 1 gallon (about 4 liters) of fuel every second. Over the course of a 10-hour flight, it might burn 36,000 gallons (150,000 liters).

In some cases, such as the “Miracle on the Hudson”, the aircraft is ditched without major damage and it may actually float for some time. Eventually, all of them will sink. A “crash” implies an uncontrolled landing in which the aircraft is significantly damaged and will quickly sink.

In these cases, the airplane may arrive at the landing airport at a weight considerably above the maximum design landing weight. The pilot must then decide whether to reduce the weight prior to landing or land overweight. The weight can be reduced either by holding to burn off fuel or by jettisoning fuel.

With today's fuel prices, it costs about $450,000 to fill up a Boeing 747, depending on your market. By contrast, the Gulfstream G280, a popular business aviation aircraft, costs around $8,000 to fill.

Can Boeing 737 dump fuel? No, it has no equipment to dump fuel. Simplified reason: Fuel dump equipment is only required when the Maximum Takeoff Weight and Maximum Landing Weight differ by more than 105%.

Air carriers buy fuel from multiple suppliers at differing rates and in different locations. Not every supplier operates at every domestic airport that a carrier may serve, so multiple arrangements are necessary, including transporting fuel from a market center to the airport.

Can a large modern jet airliner plunge intact underwater from flight? No. Large airliners are not desgned for this and are not even strong enough to make a landing on water in less than perfect conditions. striking the surface at a larger angle would certainly lead to widespread disintegration.

As the Boeing 747 flew over Mauritius in the middle of the Indian Ocean, the pilot reported smoke in the cabin. A few minutes later, the plane crashed into the ocean, killing all 159 passengers and crew.

Pilots are trained to shut outer air vents to prevent water from seeping in and aim for calm waters. They will do their best to keep the plane parallel to the waves and try to land tail down for a smoother landing. This is also to prevent the plane from breaking apart and ensure it will float.
