Tescoapp, I'm aware of flying commercially in Class G, occasionally approaching ABZ we would "stray" when positioning for R34, not nice in IMC with a full B737. A quick solution would be to mandate flying in controlled airspace, where available, for all commercial operations and to be included in the ATO ops manuals. As for biz jet SOPs, of course there is, in the ATO/AOC docs. (and not including shortcuts to reduce costs!)
