ELI5: Explain Like I'm 5

Low level windshear alert system

Imagine you're on a swing in the park, and you're swinging really high. Suddenly, the wind changes and blows in the opposite direction. Your swing slows down really quickly, and you feel a jolt. That jolt is like what happens to an airplane in windshear.

An airplane is a bit like a swing in the sky. It has wings that help it go up and stay up. But when it encounters windshear, the wind changes direction quickly and can make the wings lose lift, just like you lost momentum on the swing.

The Low-Level Windshear Alert System helps pilots know when there's windshear ahead. It uses special instruments to measure wind speed and direction, and it can detect when there's a sudden change in wind speed or direction. If it detects windshear, it sends an alert to the pilot, who can adjust the plane's flight path or speed.

Think of it like a special alarm that warns pilots when there's a problem ahead, just like a smoke alarm warns you when there's smoke in the house. By knowing about windshear in advance, pilots can make sure that everyone on board stays safe and comfortable during the flight.
