Do pilots dump fuel before landing?

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.

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.

Air Canada Flight 143, commonly known as the Gimli Glider, was a Canadian scheduled domestic passenger flight between Montreal and Edmonton that ran out of fuel on Saturday, July 23, 1983, at an altitude of 41,000 feet (12,500 m), midway through the flight.

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.

In most cases, airlines only dump air in midair immediately before landing. They don't do it before or during takeoff, nor do they do it halfway through their flight. Rather, airlines may dump some of their airplane's excess fuel immediately before landing so that it lowers the weight of their aircraft.

What's more bizarre is that they do it in the air while flying. Tossing fuel into the air is a safe procedure for a good reason. Additionally, it is not as wasteful as it seems. Fuel disposal can occasionally be less expensive than not doing so.

MORE DETAILS

In commercial aviation fuel is dumped rarely. Only if the aircraft is taking off above max landing weight and an emergency takes place shortly after takeoff would a commercial aircraft be required to dump fuel.

Q: Why do planes speed up before landing? The airplanes do not increase speed before landing. But when landing gear and flaps are set to landing position, they create a lot of aerodynamic drag. Therefore, engine power is increased to maintain the approach speed.

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.

While the exact answer varies from jet to jet, most of them can fly at least 60 minutes without refueling. Based on the aircraft's size and weight, a private jet's range may be anywhere from 2,000 nautical miles to 10,000 nautical miles.

In 2016, ATSB confirmed Shah's home flight simulator had been used to plot a course into the southern Indian Ocean. Bailey believes Shah depressurised the plane to incapacitate his passengers and crew, before flying the plane solo for the next six hours until its fuel ran out.

Theoretically it is possible but even a supersonic jet would be hindered by factors such as speed restrictions and in-flight refuelling.

Air Transat Flight 236 was a transatlantic flight bound for Lisbon, Portugal, from Toronto, Canada, that lost all engine power while flying over the Atlantic Ocean on August 24, 2001. The Airbus A330 ran out of fuel because of a fuel leak caused by improper maintenance.

In this case, the aircraft will try to do it overland (not water) or away from populated areas, as it is the equivalent of dumping thousands of liters of petrol onto an urban area. The FAA mentions explicitly that any dumping can't occur under 2,000 feet.
