What Jets can dump fuel?

Aircraft such as the Boeing 707 and 727 and the Douglas DC-8 had fuel dump systems. Any of those aircraft needing to return to a takeoff airport above the maximum landing weight would jettison an amount of fuel sufficient to reduce the aircraft’s weight below that maximum landing weight limit, and then land.

Can fighter jets dump fuel?

Most fighter jets can dump fuel, but most don’t need to. Fighter jets use massive amounts of fuel in normal operation and a run or two with afterburner can reduce its fuel load considerably.

Do fighter jets jettison fuel tanks?

In real combat, external fuel tanks are jettisoned when empty or as soon as the aircraft needs to get rid of them to accelerate and maneuver against an enemy fighter plane or to evade a surface to air missile. Several thousand drop tanks were jettisoned over Southeast Asia during the Vietnam War.

Can A330 dump fuel?

Not all planes are capable of dumping fuel. Boeing’s 747 and 777 both have the ability to jettison kerosine, as has the Airbus A380 and an A330. However, regional jets such as a Boeing 737 and Airbus A320 can not. “For some planes, landing and takeoff limits are the same, in which case it doesn’t matter.”

When can an aircraft dump fuel?

A pilot will choose to dump fuel only on very rare occasions. In the case of an emergency situation the flight crew can decide to dump, dirty up the plane or land heavy. The dumped fuel evaporates before it hits the ground.

What happens to fuel dumped by airplanes?

When an aircraft decides to dump fuel at altitude, the pilots flick a switch in the cockpit, and pumps push the fuel out of nozzles in the wings. The fuel disperses over a wide enough area that the particles evaporate into a fine mist.

Why do planes have to dump fuel?

The reason to dump fuel is simple: to drop weight. Any given aircraft has a Maximum Landing Weight (MLW) at which it can land, and in most cases that weight is lower than its Maximum Takeoff Weight (MTOW).

Do fighter jets dump fuel before landing?

Instead of being wasteful, it is actually a very efficient way to fly because it lowers the weight of the plane, causing it less stress as it lands. Usually, airplanes won’t dump fuel in mid-air or when taking off or landing; they only do so immediately before they land the plane.

Do commercial jets dump fuel?

During a normal flight, the plan is to burn fuel so the plane’s weight will below that number by the time it lands. Some airplanes – usually larger ones – have the capability to dump fuel to reduce the landing weight. Dumping fuel can reduce the weight quickly, dumping thousands of pounds in a few minutes.

Where is fuel tank in fighter jet?

Fighter jets and helicopter have fuel tanks to store fuel ie ATF aviation turbine fuel. In case of a fighter jet, the tank may be in the wings or at times in the main fuselage area behind the cockpit. At times fir longer flights, additional drop tanks are carried for longer endurance.

Why do jets drop fuel tanks?

Drop tanks were originally designed to be jettisoned when empty or in the event of combat or emergency in order to reduce drag and weight, increasing manoeuvrability and range.

Do all aircraft have fuel dump systems?

Jets flying with US airlines in the 1950s and early 1960s tended to have fuel dump systems but today, a lot of planes do not have this feature as they are designed with possible overweight landings in mind. For example, a Boeing 757 has no fuel dump capability as its maximum landing weight is similar to its maximum take-off weight.

What is “fuel dumping”?

But it turns out that the practice of “fuel dumping” or “fuel jettison” is a fairly well-established procedure used by planes primarily in certain emergency situations to reduce the aircraft’s weight.

Can a Boeing 757 dump fuel?

For example, a Boeing 757 has no fuel dump capability as its maximum landing weight is similar to its maximum take-off weight. When there is a need and capacity to proceed with fuel dumping this is coordinated with air traffic control, and precautions are taken to keep other aircraft clear of such areas.

Why do some planes dump excess fuel when landing?

As such, landing with that extra weight could cause damage to the aircraft. To avoid this and maximise passenger safety, some aircrafts can dump excess fuel.
