I hate to burst anyone's bubble, but last time I checked "maneuvering" speeds are more a small airplane kind of thing. while usually preventing "bending" by stalling first, large planes rarely use maneuvering speed...indeed my 737 manual doesn't even publish it.

please remember that rough air penetration speed IS NOT the same as maneuvering speed. DP Davies' book, "handling the big jets" goes into some detail about starting around page 220 (third edition).

While a maneuvering speed can be calculated, pilots of transport planes often don't have access to this(glass cockpit planes might have a display of this, but chances are that a g meter is somewhere in the loop of this?). Small planes have a nice placcard or other markings telling what maneuvering speed is for max weight.

And yes, a 60 degree bank, properly coordinated maintaing altitude turn should give you 2 gs (positive)
