Why Full Flaps Create SO Much Drag

[00:00:00]Which brings us to section three, the lift and drag trade-off.

[00:00:04]So, the really crucial point here is that extending flaps isn't just a simple on-off switch. When you drop partial flaps, let's say to 10°, you get this massive immediate increase in lift with only a very small penalty in drag.

[00:00:15]That's perfect for taking off or starting an early approach. But, as you push that lever further to 20, 30, or even 40°, the aerodynamics shift dramatically. Your lift essentially maxes out, but the drag absolutely skyrockets because you're creating massive airflow separation and turbulence. Those full flap settings are exactly what you want when you need a super steep approach or a short field landing.
