FBM, you are out of date. The aviation medical training requirement for GMPs (GPs in UK speak) was dropped from the early proposals from EASA, under pressure from certain representative organisations. The GP only needs to register once with the UK CAA, online, to inform them he is doing / going to do LAPL medicals. MED.D.035 (b) of sub part D of Annex IV of the Air Crew Regulation (EU 1178/2011) states that in order to issue LAPL medical certificates a GMP shall be fully qualified and licensed for the practice of medicine in accordance with national law. Sub section (c) states that GMPs acting as AMEs (for the LAPL) shall notify their activity to the competent authority.
