Helimutt I sense your frustration in thinking that some people are finding a back door way to keep flying when a single doctor tells them that they are unfit. Or indeed when several doctors who are following the letter of the regulations of their country tell them so.
The UK, and hence the new JAR medical is known for being a mix of all the previous medical restrictions of EEC countries rolled into one. It is a prototypical horse designed by a committee. It bears very little resemblance to a medical system which keeps medically unfit pilots grounded and fit pilots flying.
Many, many other countries in the world see the bureaucratic stupidity of JAR and decide to apply their own standards to flight crew licencing, and indeed to many other areas of aviation, most particularly engineering standards. These countries are often guided by what they see as a good working system under the FAA and then modify them to become a kind of localised FAA. They are often more restrictive than FAA but still far more sensible and practical than JAR.
Medical is the case in point here. We are not suggesting that underacloud should go to darkest wherever and get the best medical that money can buy, but that he should try to pass a medical in a jurisdiction where sound medical principles apply over bureaucratic nonsense.
There is a lovely description in a boating book, "Sods Law of the Sea" when it describes one of the more eccentric yachties on the east coast of England. To paraphrase, "It wasn't that he was getting worse, it was just that as the National Health got themselves more organised, their idea of normality deviated further from his."
Think about it. It's so true in aviation medicine today.
