it must be the same for a normal wing if it lifts it goes slower so it has exactly the same behaviour that a flat wing, why to use normal wings if with flat wings you can lift as high by pitching up?
the only advantage can be that normal wings lift without losing speed, free energy
but what would be of this world if plumb could turn into gold, petrol was useless and you could irrigate africa turning it into what it once was, no wonder that bull on subpressions that everybody say they understand but actually nobody does
The reason you don't see the point is probably also why you're not an aeronautical engineer. Just because something isn't innately obvious to you, that doesn't mean it's wrong
