Tks for the above. Sticking strictly to EASA Part FCL, my licence privileges under FCL 905 includes para. (g),(g) (IR(R). I assume because my previous JAR FI rating lifted the instrument restriction, I maintain FI instrument privilege, even though I haven't qualified as in the para (g) 1,2.
And on the basis that instruction or examination can only take place if the same qualification is held (or higher), I can instruct/examine the PPL/IR or en-route IR when I gain these ratings, or of course resurrect my lapsed SEP/SP IR.
