Hi Phil
At the moment the UK exams are still valid for the issue of a JAR ATPL, as I said previously, however next year it looks as though EASA licensing requirements may start taking effect. At the moment the UK CAA can say they accept their old UK ATPL exams for the issue of the UK JAR ATPL, as JAR isn't european or UK law, and the UK CAA has to go by their own law in the ANO.
However next year it'll be european law, and the UK won't have the power to automatically say the exams are valid. The EU/EASA may simply say they accept JAR exams or the new EASA exams, and the UK can't do anything about it unless EASA says they'll also except national exams pre JAR. Who knows if they'll say the latter??
