Okay kiddo, have you ever been on a plane before? When you get on the plane, the pilot and the air traffic control people need to tell you what's going on with the runway and other things that could impact the flight, right? That's where the Automatic Terminal Information Service (ATIS) comes in.
ATIS is like a special message that tells pilots and other people who work in the airport what's going on with the weather, runway conditions, and other important information. It's automatic because it's pre-recorded and played back to everyone who needs to hear it.
Imagine you have a special toy that says the same thing every time you push a button. That's kind of like what ATIS is - it always gives the same information about the airport. But it's really important because it helps everyone who is working at the airport, especially pilots, know what to expect and how to fly safely.
So when you hear the pilot or someone else mention ATIS, now you know it's like a special message that tells everyone what's happening at the airport.
