Also ORS4 no. 711 (now no. 756) was launched without any RIA, so NPLG is losing revenue to SEP pilots able to use these exemptions with their UK-issued pilot licences who would otherwise have needed a NPPL(SSEA).
That's an interesting take on it - I had wondered what the RIA had to say about the potential for lots of PPL AMEs going out of business, but if there was no RIA that answers my question!
