    Dear friends and followers, welcome back to my channel! Today's video will all be about the fuel jettison procedure, or better known as "FUEL DUMPING". Why do pilots dump costly fuel overboard, after you´ve just paid for it as a passenger? And what a terrible pollution of the environment! So pilots have to have a good enough reason why they do that?
    As jets began flying with US airlines in the late 1950s and early 1960s, the FAA rule in effect at the time mandated that if the ratio between an aircraft's maximum structural takeoff weight and its maximum structural landing weight was greater than 105%, the aircraft had to have a fuel dump system installed. 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.
    And in our case, we have a medical emergency just beyond the coast of Scottland which forces us to land at the next suitable airport, which is Dublin. Then we´ll do the math on how much fuel we actually have to dump in order to safely land at Dublin airport below the maximum landing weight to not damage the airplane.
    We´ll quickly go over the fuel dumping panel and the actual fuel dumping hose of the Boeing 747.
    I hope you enjoy this basic explanation video on the fuel dumping procedure.

    wait so if you’re in a 737 and having an heart attack it is more likely you will die? Since the pilots need to consume the fuel by flying for hours maybe?

    is their a certain altitude you can only fuel dump at? using your example of 45mins out from dublin and 35mins to fuel dump but you have to land as well will you be in a holding pattern to fuel dump before dropping altitude?

    A few years ago there was a commercial jet that had to dump fuel over the state of New Jersey because it was having some kind of problem and lots of people saw it dumping the fuel and flying low. They called 911 because they thought it was going to crash. I have a fire department scanner radio and I happened to catch their calls for all the fire departments in the area to "standby for possible commercial jet crash" It was pretty shocking. I immediately picked up the phone and called my parents who were out shopping and told my mom, "Guess what they just said on the scanner! You're not going to believe it!.." That was a radio call I never thought I'd ever hear, or ever want to hear ever again. Luckily, it landed safely. But the weird thing about it, was that it was never anywhere near where I live, but all the fire departments in my town were still preparing for it and sending out the radio call for some reason.

    I don't know what countries this video applies to but in USA there are laws from Evironmental Protection Agency, Coast Guard and State agencies that prohibit allowing hazardous substances to be leaked into the environment. I've heard it said at boat refueling docks that one can receive severe fines for leaking only a drop or two of fuel into the water. Also, tanker ships and offshore petroleum drillers are fined enormous amounts for cleanup of oil spills. So, how is it legal for planes to be polluting the environment with TONS of fuel being dumped not accidentally, but INTENTIONALLY?

    • A2DJP
      A2DJP 11 days ago

      Dmytro Picky because the max landing weight is much closer to the max take off weight, so it’s simpler to just burn off the fuel, or do an overweight landing

  • charan teja

    what if flight have to land immediately after takeoff?

    • Alessandro Mancino
      Alessandro Mancino 7 days ago +1

      Then the pilot lands the aircraft (or at least he/she tries).
      If the plane can sustain the impact without becoming damaged, it will. If it can't, it will sustain varying degrees of damage (depending on a number of factors and plane model).
      It isn't that you can't land a fully loaded plane (regulations would prevent such a plane to take off in the first place): it is just that, by dumping fuel, you can save on the costs (deriving from possible structural damage to the carriage and/or airframe) and reduce the risks of an emergency landing.
      The procedure described in this video is an EMERGENCY PROCEDURE, and a rare one on top of that.
      You can be sure no airline would be happy to squander tens of tons of jet-fuel meaningless. They paid for it, and now it is gone. And guess what, if the plane redirected for a medical emergency, it is likely that the airline will have to buy another load of fuel to replace the dumped one so that the plane can now complete the trip!

    How about inventing something that fuels canisters with that fuel which then gets ejected safely with some kind of parachute or something people are able to pick up later? Or make designated dropzones for those where then we do not only not polute the atmosphere further but also safe gallons of fuel?
    Oh wait... money.

    • Derethevil
      Derethevil 11 days ago

      See that is why i said maybe think of a way better solution. There are surely chemicals out there which will prevent that from happening. Why not mix those on board and then jettison them? Even if the fuel is useless afterwards, that is still a lot better than spewing them out into the air all the time. In my opinion i do not even understand why everyone needs to fly all the time for vacations. Surely that is just me who doesn't need a fancy vacation to relax but if humanity really is interested to safe this planet, they eventually have to realize that they need to cut down in those practices in order to achieve this goal.
      Otherwise there has to be a better solution. Everything is better than poluting the air further with this. Surely unburned it isn't as bad tho still bad enough. If there is anything one can do about it which prevents that and maybe even safes this fuel for later it should be researched properly.

      that'd actually be super dangerous in practice, while the container could be dropped and parachuted rather safely and not make contact with anything before the ground, who knows where it'd actually land and how safely at that, particularly being a fuel container that could upright explode on contact and especially under sunlight (hence the sunlight warning on jerry cans). The fuel vapors are particularly an issue alone if they were to leak out of the container during drop (pressure change) or on impact, it's essentially airborne TNT and what causes most fuel fires and explosions.
