Icarus,
I understand what you and Cargorat are saying however, I do disagree with you as far as the NOTOC is concerned. I know that the "signature" signifys the undersanding and awareness of DG being aboard the aircraft. However, the PIC may not accept the pkg if it has not complied with the IATA DGR. That is everybody's responsibility down the chain. The PIC shouldn't be just limited to "signing" and "flying".
Thanks
