We are all taught the correlation between bank angles and g forces in level flight. For a long time now I've wondered what effect a climb or descent has on this. I've looked around for some sort of a formula but come up empty handed.

The reason I ask is that I've been trying to get a better understanding of what's happening on a descending turn to final and the effect on stall speed.

Can anyone provide a formula or something I can work with on this?
