Airspeed

Airspeed is like how fast you're going in an airplane. You know how when you're running, you can tell how fast you're going because of the wind in your face? Well, it's the same idea in an airplane. The air outside is moving, and the plane is moving through it.

Airspeed is measured using an instrument in the cockpit. It helps the pilot know how fast the plane is going. The faster the plane goes, the more air moves over the wings, which helps the plane stay in the air. If the plane is going too slow, it might not be able to stay in the air anymore, and that's not good!

So, airspeed is really important to keep track of when flying an airplane. It helps the pilot know if they need to go faster or slower, and it helps keep everyone safe in the sky.
