Hi Mathewlai, Its all to do with how the plane reacts to different All Up Weights (AUWs.)

If you throttle back to just 70 knots with just yourself on board, then pull fully back, you will not be able to pull more than say +2G.

Try the same at max AUW (full of passengers and full fuel.) and you will not get +2G but maybe just 1.5G. To get the 2G, you will need to fly faster when fully loaded.

Increase the speed to beyond Va and it is then possible for you to exceed the +4G limit of most planes, with full deflection of the yoke. Again Va will be higher when fully loaded, by a factor that I think is proportional to the squre root of the increase in weight.
