dear friends and followers welcome back to my channel and greetings from the Airbus a 320 simulator at the TFC flight training center here in Essen Germany. This is video number 3 out of 10 Airbus introduction videos and today, I’ll be giving you a basic explanation of the Airbus A320 fuel system So let’s get started (Air Traffic Control Radio) (Up beat electronic music playing) The A320 fuel system consists of the fuel tanks, controls the distribution of the fuel during refueling, supplies fuel to the engines and apu cools the oil for the integrated drive generator lubrication system keeps fuel in the outer wing for wing bending and flutter relief and supplies information on the Ecam and cockpit indication Within the cockpit we have all the related fuel switches on the overhead panel and the Ecam display showing the fuel panel after pressing the fuel button on the Ecam control panel. Other than that the Ecam will automatically display the fuel page in case of a system failure or warning. Outside of the cockpit you can find a refueling panel on the lower part of the fuselage, below the right-hand wing and the refueling coupling in the midsection on either side of the wings The fuel is stored in three tanks: the left and right wing tank and the Center tank The wing tanks are further divided into a inner tank and a outer tank. The total usable fuel capacity is 23.858 liters or 6302 US gallons on the Airbus A320 model. Okay, let’s look at the Ecam fuel display. Starting at the bottom we have the FOB, the fuel on board Moving up we have a scheme of the wing tanks, each showing the current fuel quantity and the fuel temperature Except for the one in the center tank, which isn’t exposed as much to the outside air temperatures compared to the wing tanks. Then you have the fuel pumps, the crossfeed valve and the fuel lines Towards the engines including the low pressure fuel valve. Number one and two represent the engine one and two plus the fuel each engine has used since engine starts and the sum of that. Now as you can see there is a barrier between the outer wing tank and the inner wing tank. That’s there for a specific reason, the fuel systems will primarily empty or use the center tanks first then the inner tanks and as soon as the inner tanks reach a fuel level of 750 kilograms, a transfer valve will open, let in the outer wing tank fuel flow into the inner tank by gravity. The reason therefore is to reduce wing bending and control wing flutter during flight. Now, you can see that each side is isolated from each other, but if there were to be any abnormality, like an engine failure for example, a fuel imbalance could create a further problem. That’s where the crossfeed valve comes to play. Normally the valve is closed, but setting it into the open position, fuel then can be transferred from the heavier side to the lighter side using the fuel pumps accordingly. There is a total of six identical fuel pumps: two in each in a wing tank and two in the center tank. When the wing tank pumps are selected on, they operate continuously, providing necessary pressure to the fuel line feeding the engines and are manually switched off after the engines are shut down and reaching the parking position. To make the system redundant, suction valves are installed in each wing tank. So in case both fuel pumps fail in a wing tank the engines can use suction pressure to extract the remaining fuel from the tank. But there aren’t any suction valves installed in the center tank. Therefore in case both center tank pumps should fail, the remaining fuel is not available from the center tank Also, the fuel is limited by temperature. The minimum temperature for jet A-1 fuel is -43 °C and a maximum of +45 °C. To counteract from fuel freezing up in cruise, Airbus has installed a fuel-to-oil heat exchanger. During flight, the cold fuel cools the hot oil of the integrated drive generator and at the same time the oil warms up the fuel to prevent it from freezing. That’s it for today I hope you enjoyed the basic introduction video of the fuel system on the Airbus A320 Thank you very much for the support by TFC providing me with this great flight simulator and see you next week. All the best, Your Captain Joe. Electronic outro music playing

  1. It would take 26 tower cranes to lift the weight of the fuel alone on an A380 bus. You know those big towers that build skyscrapers? 18 tons of fuel in each thin ass wing weighing just sloshing around on bank turns. Haha. Ok. People need to look into compressed air engines they're using it right in front of us. They are even started with compressed air.

  2. cartoons, make a footage of fuel pump, fuel tanks etc and let us see how you fuel the flying busses… i can paint for you how i fuel my starship i have in the attic and dress in star trek uniform… friggin zombies..

  3. The wings don't seem big or strong enough to hold all the fuel. Are you sure the planes don't just run on compressed air?

  4. Having the fuel stored in the wings doesn't it increase the risk of engine explosion in case of a faulty situation?

  5. Captain you should not lie to people. Be honest, wings are so tiny and have loads of hydraulic stuffs for spoilers. Wings never have any tanks and jet tribune runs on compressed air.

  6. Some please google what a 23,000 liter tank looks like. Plus how?? How ?? Can the file be in the wings ?? Where does all the hydraulics fit???

    Here it is; https://www.google.com/search?q=23,000+liter+tank&client=safari&hl=en-us&prmd=simvn&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjp3L_i8v7ZAhUJyYMKHWiUCIMQ_AUIEigC&biw=414&bih=622#imgrc=dcVyk49Yn_4W8M:

    So basically this plane carries a tanker???

  7. can i regular person that's not a pilot go and play in one of those simulators ? i wanna see if i can take off or land without any training.

  8. Why is this done by pilots/crew, and not monitored and controlled by a computer? (with redundant systems of course)

  9. captan joe i really love your videos and you are encouringing me to be a pilot and i heve a question what plane do you fly
    airberlin?
    air france?
    emirates?

  10. 1:34 – the older A320/319's have the fuelling panel on the right wing, almost next to the nozzle port. The newer ones have the panel where you showed us and that's better. Too bad the nozzle still has to connect up on the wing.

  11. What if they're lying to us and air is what really help an aircraft fly so they can raise airline tickets?
    I suppose a little fuel is used for lifting weight but I strongly believe these aircraft fly on air

  12. I remember the incident of Air Transat flight 236. They had developed a fuel leak in one of the engines. This subsequently caused a fuel imbalance in the fuel tanks. Following the protocol, they opened the cross feed valve to balance the tanks, not realizing that the reason for the imbalance was because of a leak. This action subsequently drained both tanks and they ended up gliding several hundred kilometres without fuel. What I don't understand is if they were monitoring the tanks as they should be, why did they not close the cross-feed when they realized that the imbalance was continuing and that they were consuming fuel at an alarming rate.

  13. AIR…bus not FUEL..bus they run on AIR…AIRplanes at tbe AIRport fly over a plain flat surface.

  14. Good video. In ACJ, additional fuel tanks are added for more range. So where are these added ? In cargo hub or somewhere else ?

  15. You are liers. You said that the fly had 23.858 litres, and the oficial version is 248-296 t. Captain joe you are a hoax man. bye

  16. just finished watching few clips on jet fuel hoax and I came across your clip about the fuel system. Your video just completely woke me up from almost believing that we're being lie about paying for fuel charge, that airplane are run by compressed air not by fuel. Anyhow, just got a few question I like to ask if you have a moment. 1. From the Jet Fuel Hoax clips they mentioned aircraft wings will NOT ever have ability to carry such heavy load of fuels on both wings. I am finding this reasonable. What do you think about this? Does aircraft wings really can sustain weight as much as 4 buses on each side of wings??
    2. how do a fully fueled airplane keep its center weight balanced when turning (banking)

  17. 1-Where are the 85,000 gallons of LIQUID Jet A fuel stored on the A380? 2-How do they fill the A380 with 85,000 gallons of LIQUID Jet A fuel in 45 minutes? 3-What is the total $cost to fill up the A380 with 85,000 gallons of LIQUID Jet A fuel. 4-How are the A380 jet engines able to atomize and burn 85 gallons of LIQUID Jet A fuel per minute?

  18. Dear Joe!
    Thank you for interesting videos! They are nice!
    Could you confirm one moment of Airbus SOP?
    When we are flying below transition lever, we are announcing to PM altitude, which set on FCU, i.e. "Six though and blue" etc. But what about situation when ATC gives to climb to FL 240, for example? What PM should say for announcing? "Fl240 blue" or "24000 ft blue"? Transition altitude didn't assed yet. Thanks!

  19. Joe are you serious? 18.9 tons of fuel? Now that’s a hum dinger of a story. Did you learn that in flight school because in the real world that much weight would take a hell of a lot to get off the ground. How much does a car weight? Hum now stack those on the wings and center of plane. It’s funny that when you just throw out numbers people believe but give them a visual and things change.

  20. Hey Captain Joe, what do you think about the "jet fuel hoax" do you think they are charging us more for fuel that is not used?

  21. Why are people BELIEVING this GARBAGE!! This plane does not run on the so-called fossil fuel. DON'T JUST BELIEVE THIS VID DO THE RESEARCH😂🤣😂🤣😂

  22. you did not talk about the wing tank vents on the Airbus 320….. They produce an annoying hauling that drives people MAD with the most terrible whining sound your ears can tolerate that far surpass the engine noise. This noise victimize communities under the plane path within 20 miles of an airport. all so airlines could profit by victimization of communities all over the world . this type of aircraft should be outlaw.

  23. Fuel storage 23,000 L ie tons!! FOB says 7,520 !!!!!! Errrrrrrr you're lying 23,000 tons of fuel is a joke on a aluminium plane!! taking you have passenger weight, cargo, baggage, What those wing tanks are is compressed helium tanks and the plane engine run themselves on compressed air.

  24. Hey Joe, (reminds me of Jimi Hendrix)…are you really a Captain?….it's just that you have only 3 stripes instead of 4 on your epaulettes. They're supposed to be 4 right?

  25. I heard about a procedure that says that we need to switch off the center fuel pumps if we have less then 500kgs in it… can you tell me more about that ?

  26. Superb explanation sir, smooth crisp and informative.. Never felt like loosing control on video..
    Hatts off

  27. Can you transfer fuel from left tank to right tank using x feed or is it only to feed the engine on the opposite side?

  28. Triple redundancy is very important in aviation. So… if Captain Joe hasn't uploaded a video, I watch Mentour Pilot. If Mentour Pilot hasn't uploaded a video, I watch Dutch Pilot Girl; and if SHE hasn't uploaded a video, I watch the 'Something In The Air' channel, which is only about kites, but it has some quite nice music… 🙂

  29. I just realized how close my birthday is to yours mine is June 2nd and yours is June 21st if I'm not mistaking.

  30. Fuel To Oil Heat Exchanger Is Very Simple And Brilliant Idea
    Little Things Make Big Difference In Aviation That's Aviation Is So Much Too Me

  31. Consider this, if you fly in an airbus, the pilot is controlling WITH HIS LEFT HAND!!!! THIS is just messed up!!!

  32. how strong are the cantilevers? amazing how they hold all that weight. Also amazing how all that weight reacts in turbulence. I feel like there may be some fibbing about how much fuel is used by commercial airline travel. But I am sure you and the fan boys will DEBUNK any thoughts that might cause decent. Im sorry, all your work is for the technocratic elite who own us. Hey Captain Joe! Have you ever filled the fuel tank yourself?

  33. how long does it take to pump 100,000 litres of fuel through a 4 inch hose? taking static friction into account of course.

  34. mmember that time Tom Hanks landed a fully fueled 747 in the Hudson River? Mmmmember when it floated and all the imagery of the ferry boats saving the people all STANDING on the wings FLOATING with ease untop the lapping river?

  35. Captain Joe, im sure you are not lying to us. You have just never pumped your own gas, so why would you know. This also takes psychological stress off of you, you aren't responsible for other men's lies. BUT! oooohhh Captain Joe! if you looked into how the fuel system works with an honest heart, how much fuel are they really pumping through those 4 inch coupled hoses? Come on Joe! take a red pill! ask some questions! Dont be a toe to the corporate line Joe!

  36. Commercial aircraft don’t use fuel,advancements in engine technology means that they don’t use fuel,the power comes from compressed air..the thickness of the wings has decreased dramatically over the years,so now we pay in the price of the ticket,fuel that is not there in the wings…

  37. Joe you know you are very popular on Real Flight Simulator everyone is talking about u on any server. Even me XD

  38. Excerpt from patent
    for producing liquid oxygen to be utilized as the oxidant for a non-air breathing engine utilized to propel a vehicle, such as an aircraft.

    Non-air breathing engines of the type disclosed in pending US. patent application Serial No. 417,867 filed March 22, 1954, by Randolph Samuel Rae and entitled Non-Air Breathing Engines can utilize low temperature liquids as the fuel and oxidant. When such engines are utilized forpropelling vehicles, such as aircraft, the liquid fuel and liquid oxidant can be carried in separate tanks within the vehicle and such tanks are supplied with suflicient amounts of the liquid substances to propel the vehicle for the required time. When the engine is used to propel an aircraft, it is obvious that unnecessary weight could be eliminated if the liquid oxidant were produced continually throughout the flight.

    By the present invention, it is proposed to produce the liquid oxygen continuously throughout the flight of the aircraft so that only the amount of oxygen needed tomaintain the flight of the aircraft will be carried by the aircraft
