I agree, Wouter - nicely well worded reply.

Bill - one minor point:

The the plane is taking off and landing the flaps are down (high angle of attack) and extended aft. This creates more lift and power.


The flaps increase the camber, not the angle of attack. More camber creates more lift at higher angles of attack (without stalling), but at the expense of greater drag. The extended flaps (and leading edge slats) also introduce a slot that helps the airflow remain attached (not stall), as does the slot on the sailing wing.
