Okay kiddo, you know how cars need gasoline to run? Well, airplanes also need fuel to fly, but it's a special kind of fuel called aviation fuel or aviation gasoline.
This fuel is made up of a mixture of different chemicals, including hydrocarbons like kerosene and gasoline.
The reason airplanes need this special fuel is that they fly much higher and faster than cars, and regular gasoline can't handle the high altitudes and temperatures they experience.
The fuel is stored in big tanks at airports, and then pumped into the airplane's fuel tanks before takeoff. The amount of fuel the plane needs depends on how far it's traveling and how big the airplane is.
Aviation fuel is carefully regulated and tested to make sure it's safe and efficient for planes to use. And, just like with regular gasoline, airplanes have to stop and refuel if they're flying a really long distance.
So, basically, aviation fuel is like the special juice that makes planes go "zoom" up into the sky!
