ELI5: Explain Like I'm 5

Blind approach beacon system

So imagine you are playing a game of hide and seek with your friends in a big park. But you don't know where your friends are hiding! So what you do is use a whistle to make a loud noise that they can hear. When they hear the whistle, they know where you are and can call out to help you find them.

Now, imagine that airplanes are playing a game of "hide and seek" in the sky. Sometimes they can't see where they are going because it's foggy or they are flying at night. That's when they need a Blind Approach Beacon System (BABS) to help them land safely.

Here's how it works: The BABS is like your whistle in the game of hide and seek. It sends out a signal that airplanes can hear when they are close by. The signal helps the airplane know where the airport is and where to land safely.

The BABS is like a big lighthouse that shines a signal in the sky to help guide the planes to the right place. Just like your flashlight at home helps you see where you are going in the dark.

This Blind Approach Beacon System is very important to help planes land safely in bad weather or at night. It helps pilots know where they are going and keeps everyone safe.
