What are you talking about? Inertia of the plane, inertia of the wind gust? Inertia isn't resolved by G-Forces.
Inertia is the resistance of any physical object to a change in its state of motion or rest. It can be measured several ways, G-Force is one of them.
G-Forces aren't created by the bank.
Not by the bank itself, but from turn. A turn from a coordinated level 60 degree bank for example results in an inertia of 2G.
