These include:. Most types of airplane wings are flat on the bottom, but curved on top. However, symmetrical wings, which are curved on both sides, handle airflow identically, whether the plane is right-side up or upside down.
This is called the angle of attack. It can be likened to sticking your hand out of a car window. If you tilt your hand, you can feel the force upwards or downwards. This is the same for a plane. Aerobatic airplanes , also called stunt planes, have inverted fuel mechanisms that use fuel injection instead of a carburetor.
Some of these planes have a header tank, which is a separate tank for inverted flying. During a regular flight, gravity draws fuel into the tank. For upside down flights, the header tank is situated at the top of the engine, which sends fuel directly to the injectors. Instead, the oil is contained in a separate tank and is pumped through the engine whether the plane is upright or not. Fighter jets epitomize aircraft that can perform breathtaking maneuvers, including inversion.
They can pull off these tricks because of sophisticated thrust vectoring and super-maneuverability. Stunt planes that are meant to fly upside down have symmetrical wings. They don't rely at all on wing shape for lift.
To fly upside down, a stunt plane just tilts its wings in the right direction.

The way a wing is tilted is the main thing that makes a plane fly, and not the wing's shape. The angle of attack is the angle between the axis of the wing and the direction of incoming air.
