Here is one for the z axis g load induced by a level bank:
G = 1/(cos(angle of bank))
As an example since the cos for 60 degrees and 45 degrees are 0.5 and 0.707 respectively, the G load for each would be
1/.5 = 2g for a 60 degree angle of bank and
1/(.707) = 1.3g for a 45 degree angle of bank.
If you want decelerative g forces found, simply find the rate of deceleration divided by 32ft/sec^2. That is, if you are decelerating at 128 ft per sec per sec, you will be feeling 4 gs.
