I don't know who Billiebob is but I think he is ex CAA and perhaps working as an aviation consultant.
The problem with the CAA is that so many smart people have left in the last 1-2 years. The contrast between now and say 10 years ago is staggering. It is virtually impossible to get a decent answer out of the CAA on anything now - unless you know somebody on the inside who happens to understand the stuff. The people on the public interface don't seem to know anything.
Also, the CAA is maneuvering carefully on anything to do with EASA so as to protect the various historical UK GA entitlements such as the IMCR.
