Okay kiddo, imagine you are looking at a map of your town from up above like a bird. You can see all the buildings, roads, trees, and everything else. But can you imagine if there were things in the air like planes or helicopters? They also have to fly around your town, just like birds.
Now imagine that there is a rule for those planes and helicopters that says they have to fly at a minimum altitude when they are flying over parts of the town where there are buildings and people. The rule is called the “area minimum altitude” and it helps keep everyone safe.
The reason for the rule is that if a plane or helicopter is too close to the buildings and people below, it could be dangerous. If something goes wrong with the plane or helicopter and it crashes, it could hurt the people and damage the buildings. That wouldn't be good, would it?
So, the area minimum altitude helps to make sure that planes and helicopters are flying high enough for everyone's safety. The pilots have to look at a chart that tells them the minimum altitude they should fly at over different parts of the town. This helps them stay away from the buildings and people below.
That's what area minimum altitude means, kiddo! It's a rule that helps keep planes and helicopters flying safely in the sky over our towns and cities.
