ELI5: Explain Like I'm 5

Air traffic service

Air Traffic Service (ATS) is like the traffic police in the sky! They help airplanes know where to fly and at what altitude. They also help pilots make sure they don't bump into each other in the sky. ATS gives the pilots clear and accurate information from the ground like the weather and other airplanes flying nearby. They also help airplanes stay away from dangerous spots like thunderstorms. This helps keep everyone safe while flying!
