When JAR-FCL came along in 1999 they removed the requirement for ground examiners, there were 5 or 6 then, now there is only one! What will happen with the new EASA LPL and LPL(Basic) there are no exams! AOPA invented the NPPL but nobody ever produced any exams for it! The Microlight world write their own questions as did the SLMG world, but that ceased a few years ago and by default they adopted the JAA Questions.
