If the airplanes wings are shaped to create a lifting force , how can acrobatic airplanes fly upside-down ?

713 views

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.

If upside down, for example, some of those surfaces are movable and will be adjusted to counteract the natural tendency to “float” towards the ground. If you look closely, you’ll also notice that the engine is pushing in a direction that forces the plane to *not* move towards the ground. We call this orientation angle of attack.
