”Specs for the Airbus are 250 metric tons of fuel. Yep. You read that right. So I was downgrading to 200 metric tons. So the 737 only carries about 41 tons? That would be 20 tons each wing? Wowser.”

Again, there is no narrowbody aircraft, whether Airbus or Boeing, that is carrying anywhere near 500,000 pounds of fuel. I’m not sure what you’re referring to when you’re just saying “the Airbus.” Which model?

The comparable Airbus models to the B737 would be in the A320 family, and they carry a similar quantity of fuel. Very few aircraft even have maximum gross weights (which includes the full-up weight of the aircraft with fuel, passengers, and baggage) in the 500,000 pound range, much less carry that much in fuel.

From the 2005 manual with specs, says the A380 AirBus carries 320,000 litres of fuel or about 160,000 liters per wing. So where does all that fuel go? I don't understand. These jet engines need that much fuel for an eight hour trip, as it says in the spec sheets.

I screenshot'ed it but look at the book specs at 3:21 minutes

From the comments on these A380 AirBus Specs for the wings and fuel distribution:

"18 tonnes of Jet fuel at 0.785 kg/l requires 150 cubic metres. With the A380 wing area at 845 square metres (Wikipedia), that's 422.5 sq m per side.

Estimating (from the fuel tank picture in your manual) the 'wet' part of each wing comprises about 60% of total area or about 250 sq m. Placing 150 cubic metres over this requires an average wing thickness of only 0.6m to store the lot.

The wing looks at least 2 metres thick at the root and one metre thick at mid span so there's plenty of space for 118 tonnes of fuel per side. Please do pick up a calculator and follow this through if in doubt. Failing that, sniff the kerosene fumes!"

and another commenter:

"He makes a strong argument about the physics of the wings being completely off the physics chart. I looked into it. 6.8 pounds

JP-5 is a complex mixture of hydrocarbons, containing alkanes, naphthenes, and aromatic hydrocarbons that weighs 6.8 pounds per U.S. gallon (0.81 kg/l) and has a high flash point (min. 60 °C or 140 °F).

Max. fuel capacity 323,545 L / 85,471 USgal[36

That’s 578,000 pounds loaded in the wings.

Maximum take off weight 575 t (1,268,000 lb)

So half of his weight is in the wings. 😜😂🤣"
