I read somewhere that EASA had not had a great deal of response / comments on these NPA proposals
The other point about the above is that most people will comment only on what directl affects them.
For example, I fly on an FAA CPL/IR and own an N-reg plane. I will therefore comment on the foreign proposal (pages 159-161) and the rest doesn't matter. I never commented on the NPPL because it was never relevant, and since I can renew my old JAA PPL (with a checkride I think) the EASA LPL will be of no relevance to me.
To me, what matters is that pilots are taught what they actually need to know to fly safely and confidently from A to B, and this doesn't happen under the present system, isn't going to happen under the new system, and I don't see any way it will happen short of a drastic overhaul / modernisation of the syllabus (which would be fiercely resisted by the training industry).
The vast majority of people coming into contact with this proposal already hold JAA PPLs (or some other JAA-land ICAO PPL) and they just rent, so it doesn't affect them either.
Which leaves only a few to wade through the 600 pages...
