As I understand it, CAP755 (copy in front of me) makes recommendations that are NOT compulsory, and is effectively a 'voluntary miniAOC'. Companies that want to be 'state of the art' will put the required Ops manual in place (or, like us, rejigger their existing Ops Manual so that it is CAP755 flavour) so that they are whiter than white. Companies that 'don't feel like it' will just not bother. So where is the value in the document? Good organisations that are probably not a CAA concern get additional admin, others will not be impacted.
