Wondering if anybody out there can provide the equation/formula for G-loads calculations other than tables from FOM's? (Particularly on AIRBUS A/C's).

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.

Are you on the Airbus? If so, you can go into the FMS and pull up current G values. It's mildly interesting to watch it change as you maneuver around.

1000fpm = about 2.5 G's on a hard landing
