aerodynamic lift
I was long-winded last night. Too wordy.
Check this graph. Notice that CsubL is at or near its maximum at alpha = 10 degrees. The three different curves are for different aspect ratios.
Harrier ramps are inclined at a ten degree angle, I think. And the Admiral Kuznetsov had a twelve degree ramp(?). The idea is to rotate the wing to its maximum CsubL.

I believe that there's a movie from the early 1950's titled
Highway in the Sky, starring John Wayne as an heroic DC-3 pilot.
