aviatorhi, none of us has provided the prove for either of statements thus leaving us with the deductive logic and historical values. So far the odds are against the statement of 1 QRH is required for obvious reason and pro 2 QRHs on airbus fleet. Once again, prove me wrong and I have no problems to admit of being wrong.
We then take it off and replace with two of our customised QRH's on arrival at base
why would anyone do that?
