My progress: ok so we know that the plane has velocity of 180km/h which is 50m/s.

And there are two forces acting on the plane at the bottom of the loop.

Fn [upward] and Fg [downward] (in this case Fn is greater? because it's acceleration is towards center,)

fn - fg = ma

4mg - mg = mv2/r ??

is this correct ?
