Flaps and Drag

Apologies for the double up... but the video is cool.

By the way, my opinion is that this is within the realm of good airmanship and practice as that one, well worn piston engine is slightly less reliable than Flyboy and Dummy's double turbines!

I liked the part about "dispersing" energy.

Of course not. He says that you get the bet lift to drag ratio with flaps 10.

Context. He is correct within context.

Of all of the 'official' flap DEPLOYMENT 'notches', 10 degrees gives the best L/D.

Flaps 0 has no deployment and flaps 5 isn't one of the 'notches'.

And, you are avoiding my question about slow, slightly flapped drag vs. clean cruise speeds at a single altitude. :-)

He's also ignored the effect that if you try to take off with flaps 30 you'll not accelerate as fast before rotation. I would expect this effect to outweigh any tendency to rotate earlier because of the increased lift. But, I'm not an aeroengineer at all.
