I wonder how precisely it is possible to calculate this little rule of thumb: “10–25° flap add more lift that drag. 25–40° flaps add more drag than lift.”

I once read that when the flaps are at the same degree of deflection as the aileron is when also deflected, the pilot gets the highest amount of left from the flaps. I think my batty instructor told me that before slamming home his shot of tequila (eight hours before he flew again, of course).

Wow, just … wow!
