But if your national CAA will not accept EASA licenses, then you surely require one that can issue a licence that WILL be accepted? Would you find one outside Turkey?
On a sidenote, i cannot help wondering about this story. Why will your CAA no longer accept EASA licences? Nothing to do with Brexit I suppose
but perhaps it is another indication of deteriorating relations between Ankara and "Brussels", i.e. the European instances?
