Whenever I see an explanation about how airplanes can fly, I see that the shape of the wing is different on the top side to create a dragging force that pushes the airplane up. The top is curved and the bottom is flat. If a airplane turn upside down, should it fall faster because it’s dragging down ? I saw airplanes doing acrobatics on air , and some of them looks impossible because of this.

Acrobatic airplanes are not very fuel efficient. The angle of attack, the orientation of the wing to the path of motion, is also a major contributor to lift. The shape provides fuel efficiency, as that’s what the airplane is usually optimized for.
