Jan 30, 2015 · 87UL/E0 (similar fuels are called 82UL or 85UL) -- This is a tightly specified form of motor gasoline (mogas) -- without any ethanol or oxygenates in it, as many aircraft fuel systems aren't compatible with ethanol -- that is used in low-compression aviation piston engines mounted in airframes certified or STCed for operation on motor gasoline ...
How is fuel weight calculated? - Aviation Stack Exchange
Feb 20, 2018 · The maximum fuel weight is the difference between maximum ramp weight and zero fuel weight (which is 562,000−361,000=201,000kg) Max take-off weight is a bit less than maximum ramp weight, but we'll handwave over taxi fuel for simplicity. The point here is that if you can fill the aircraft with cargo, it would be too heavy if you also filled ...
fuel - Why do jet engines use kerosene rather than gasoline?
Mar 4, 2015 · natural gas is commonly used as a turbine fuel in pumping stations: it's already there and thus is "free". The required pressure vessels make it impractical to use as an aircraft fuel. So kerosene basically became the standard turbine fuel because it's: cheap: kerosene makes up a rather large fraction of crude oil.

How do aircraft keep fuel from freezing while in flight?
Initial fuel temperature. If you fuel in the middle east during the middle of summer, the fuel will be a lot warmer than when you fuel in Siberia in the middle of winter. Warmer fuel will take longer to freeze. Outside air temperature. Much like trying to freeze water to form an ice cube, the colder the air around it, the faster that it will ...
refueling - How do you know which fuel an aircraft uses?
Jul 11, 2017 · They can also often burn aviation gasoline or avgas/jet mixes but under operating restrictions that will be mentioned in the AFM. Large turbine engines will require jet fuel, and kerosene-based jet fuel at that -- they cannot run on wide-cut jet fuels such as Jet-B or JP-4, likely due to boiloff issues. These aircraft take enough fuel, though ...
