So the question is:
Is an 'IR-SP-ME class/SE' a single Rating or is it an abbreviated way of writing 'IR-SP-ME class' and 'IR-SP-SE class' and therefore an Examiner may Renew simply the 'IR-SP-SE' class on its own.
It is the SPA-IR that is being renewed, not the class rating, so no problem provided it is on the front of the licence. The examiner can sign it up. If it's on the back, just admin at the CAA post PC. I see where you are coming from, but the IR-ME has the greater privilages anyway.
Done plenty of these with no problem so far. Just go fly the profile and see what happens. If you are up to standard-pass; if not-training event.
