Okay kiddo, an aeronautical station is like a radio station that airplanes and airports use to talk to each other.
Let's imagine that you and your friend are in two different cities far away from each other. You want to talk to your friend, but you can't go to her house because it's too far away. To talk to her, you can use a phone. Just like a phone helps people talk to each other when they are far away, an aeronautical station helps airplanes and airports talk to each other even if they are far apart.
Airplanes use their radios to talk to the aeronautical station. They can say things like their location, their altitude (how high up they are), and any problems they may be having. This way, the aeronautical station can keep track of all the airplanes in the sky and make sure that they don't have any problems.
Airports also use the station to talk to the airplanes. For example, the airport can tell airplanes when they can take off and land on the runway.
The people who work at the aeronautical station are called air traffic controllers. They are like the conductor of an orchestra: they make sure that everything runs smoothly and that there are no accidents.
So, in essence, an aeronautical station is like a giant phone system that helps airplanes and airports communicate with each other to keep everyone safe.
