I think the question could be read a couple of ways. Here's my take on and corresponding answer for it:
Smooth Air Straight and Level : 1G
Turbulent Air Striaght and Level (oxymoron?) 1G + 1G = 2G
So, the turbulence is actually adding an additional
1G to the normal straight and level G-Loading.
Therefore, if we were pulling in to a manoeuvre with a 4G load and experienced the original turbulence we'd have: 4G +
1G = 5G
Hope this helps
