Consider this.
Most airplanes restrict available flap the higher elevation the airport.
At sea level, you've got gobs of flap to play with for takeoff or landing.
Go to some of them 10k+ airfields, and you're permitted very little, maybe slats only.
Why's that?
I figure it's because the denser air can press itself around the outer camber more easily and can stay laminar to a lower speed.
Get up into the thinner angel breath, and it's not so forgiving - you really have to coax those sparse molecules to stick with ya.
Thoughts?
