How do planes fly upside-down?

Question

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?

Answer 1

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
