Question

eli5 why are flaps extended during takeoff if they slow down the plane?

In: Engineering

Answer 1

Flaps slows down the plane, but also make it easier to be airborne.
During takeoff the plane need to be airborne even at slow speeds, so it uses flaps.
During landings, the plane will use again flaps because they allow it to fly at lower speeds.

To just slow down the plane, there are other components like flaps but just to brake in the air. They are called “air brakes”.
