How do planes fly upside-down?

1.02K views

I understand that the wing of the plane creates downforce, lifting the plane into the air, so how do planes fly upside-down? Wouldn’t the wings start pushing the plane down into the ground once flipped?

Wings have horizontal planes of symmetry ..so even when it flips and you brake ..what you are doing is creating same lift when you inverted…

and yes this is all in my head …but i think 🤔 they just glide more than propel up …never seen anyone gain altitude while inverted

if you have i guess its momentum ! not the wings

Not ALL planes can. The speed, the shape and size/weight of the hull and wings define if it can.
A proper example how it can be is Ziv Nedevi that flew and landed F-15 with one wing. The plane was basically a rocket – long narrow hull, relatively small and straight wings, high speed.
Also take note that even if they can do it, they can do it only for a certain time and under certain conditions.

On the flip side. Why are planes not pushed uncontrollably into the sky when under power? Climbing no matter what if the engine is running.

Aerodynamic stability.
