Does anyone know where i could find out the approx weight of a quantity of jet fuel and whether or not this is included in the max takeoff weight of an aircraft. I need to find out for a piece of IT coursework on spreadsheets.
Thanks

1 litre of fuel is .72 kg. So just multiply the number of litres by .72 Wink

And yes it will be included in the maximum take-off weight Wink

There are two types of aeroplane, Spitfires and everything else that wishes it was a Spitfire!

Jet A (which is the fuel used on turbines) has a weight of 6.75lbs/gal =1 litre is .8kg

Ozzy gave you the weight of 100LL Avgas, which is the typical fuel for pistons

And yes, the fuel weight is added to the max. takeoff weight. Without fuel, the aircraft's weight is expressed as zero fuel weight (ZFW)

The Maximum ZFW limits ensure that cabin loads do not overstress the wings in bending, because the fuel is loaded in the wings outboard and thereby reduces the wing bending moments.

Thanks for the info Nexus. Better be getting back to my spreadsheets Sad

Are there several different types of aircraft fuel then besides avgas and jet fuel.

I found another website which says that Jet Fuel weighs 62.5% the weight of water. water weighs roughly 1kg per litre (I measured it, with scales) thus jet fuel weighs 625 grams per litre. or are my scales broken?
