Pete Fanelli,
I stand corrected, but I believe Werbil might be referring to non Transport Cat a/c (particularly if he's flying around the Qhitsundays). I think that non transport cat a/c do not have to have a physical W&B completed before every flight. Of course you cannot be out of balance ... but if you are 1pob in a 210, then you know you are not out of balance and can prove it on paper if and when required.
