ELI5: Explain Like I'm 5

Localizer performance with vertical guidance

Localizer performance with vertical guidance, or LPV for short, is like having a very special map that helps airplanes safely land on a runway.

Imagine you are flying in an airplane and you’ve been told to land on a certain runway. But it’s foggy outside so you can’t see the runway until you’re very close to the ground. This is where LPV comes in handy.

The LPV map is like a secret code that tells the airplane’s computer where the runway is and how far away it is. The computer can then use this information to guide the airplane safely down to the ground, even in very bad weather.

The LPV map has special lines that show the airplane where it needs to be in the sky in order to land correctly. These lines are like a path that the airplane needs to follow. The map also has special numbers that the airplane’s computer uses to figure out how fast the airplane needs to go and how high it needs to be to follow the path correctly.

LPV is very important because it helps airplanes land safely in bad weather. It’s like having a special friend who helps you find your way when you can’t see where you’re going!
