Rolling 'G'

[Vendeeglobes]

For the aerodynamicists

I'm looking into UPRT training for large jet aircraft, specifically Boeing.

AFM limitations provide values for + and - G but no 'rolling G' (combined roll and pitch), and UPRT recovery generally separates manoeuvers by pitch and roll (not combined). During nose low recovery, the nose is often raised (unintentionally) by inexperienced trainees as the lift vector becomes more vertical, whilst they are rolling wings level, and thus inducing greater G.

Am I guessing correctly that the + and - G limits are fixed whether in a turn, rolling or wings level?

Thanks in advance..
