The annual survey at MoD airfields (done by a privatised portion of the PSA before it became Defence Estates) have been using CAP168 design criteria and reporting under CAP232. So that would say to me that the MoD airfields are probably designed to the civvy standards anyway?
By the way, HTB, is the Aerodrome Manual the master documentor the AIP? I'd be grateful for your opinion.
