Answer 1

Aircraft designed to fly upside down have an airfoil that produces nearly as much lift in normal flight as it does inverted. It relies more on thrust and elevator input to climb in normal flight, whereas a ‘normal’ airplane could fly with very relatively little horsepower but a more efficient airfoil.

I’m other words, an aerobatic airplane has an airfoil that is much more symmetrical than is typical in most airplanes.
