Could this be true? https://www.facebook.com/migyal.imisyou/videos/2514422715448542/UzpfSTEwMDAwODE2OTc1NjA4NDoyMDQxMDc4Nzg2MTc0NDI3/ A friend has posted this - of course, I have been looking around to debunk it, maybe someone can give me an answer. thanks in advance.
The fact that this even needs to be debunked is ridiculous. I have worked on both military and civilian aircraft of many, many different varieties. I have never once been called to a jet with a malfunctioning “Chemtrail” system. I have never seen a maintenance manual reference for it, never been trained on it, and have never even seen provisions for such a system that might be worked by some sort of “covert contractor.” It is either the aircraft system that all other aircraft systems should emulate, or it simply doesn’t exist.
This is perhaps the dumbest conspiracy theory ever and simply feeds on people’s innocent yet ignorant understanding of aviation. No. It is not a thing. It’s not even close to a thing.
For those who did not watch the video (btw, I have no FB account and will never have one):
It is a polemic about the fuel load aircraft can take. The author claims:
- we have been deceived by a conspiracy of airlines and aircraft manufacturers about the amount of fuel that goes into an aircraft.
- the mass of the claimed fuel volume is too heavy to be lifted by an aircraft.
- the volume would not fit into the wings.
- the filling process would not allow to pump the claimed volume in the given time.
- fuel sloshing would be an insurmountable problem.
and so on. I stopped watching after half the video because the ruse had long become obvious.
I have done many calculations on how much energy is contained in the fuel and how much is needed to move an aircraft over large distances. If you read some of my answers on the subject, the results can be found even on this site. Now for a rebuttal:
- FB is the premier platform for spreading fake information. Whoever still believes what is posted there must have been living under a rock for the last decade. So the source makes this already suspect.
- The fuel needed for a given flight is only a fraction of the maximum fuel load. This maximum is only needed for extreme range and can reach up to 40% of the take-off weight. So there is clearly enough lift capacity for the structure, the systems and the payload. Fuel mass is an issue, but it is manageable.
- The tanks are in the wings, but also in the horizontal tail and the center wing which is inside the fuselage. The tanks are not special canisters like in a car, but integral tanks: The structure is sealed and riveted tight so the whole inside can be filled with fuel. The available volume is used to the extreme, and yes, it is sufficient.
- Filling is done with special, high-performance equipment. I found the part about the claimed impossibility of the filling process to be especially ridiculous.
- Yes, sloshing is also a problem with aircraft tanks, but they include baffles and sometimes even a special foam to reduce sloshing.
My conclusion: This is yet another silly conspiracy theory and clickbait for people who don't know enough about aircraft engineering.
Funny how the video just insert non scaled fuel trucks next to the aircraft instead of... Doing the maths.
A380 wing area: 845m²
253T <=> 320 000L <=> 320m³
So how high does your wing need to be to contain that much fuel ?
322m³/845m² = 0.38m = 38.1cm
Obviously this is an over simplification but the answer is yes, it fits.
The tanks are divided to prevent that, research the site for more informations.
