Individual responses are vital, rather than everything going through one group reply, as total number of responses and a whole host of useless statistics will be counted by a team of statisticians in Euroland.
As for what you want to say, that depends on your circumstances, but most VFR pilots are likely to object for paying for significant amounts for nav / met / and comms services. How we argue against it is going to be tricky as previously it came from general taxes, now converting to "user pays".
I think that everone who flies should read the document (takes 30 mins), and reply if so moved.
The only sensible position is.....read if you want, reply if you want, but if you don`t want, don`t moan about big charges if they happen.
Enjoy the next 6 months of flying, they are likely to be the best value from here on in.
