The normal category limits are pretty high. Most people are uncomfortable if loads exceed 1g. Remember, the sense of falling unsupported is one g. I have hit a lot of turbulence in my day but the planes I was flying didn't mind.

A lot of confusion going on here. 1 G is the gravitational force everything experiences without any other input. .3-.8 G is actually less than 1 G meaning that you just became "lighter". Zero G is equal to the absence of gravity. There is a huge difference between symetrical G forces and assymetrical G forces. A fighter designed for a 9 G symetrical G force may only be able to sustain 4 assymetric G's. The assymetry causes a twist or torque which causes a lot more stress.
