Isn't the overlying issue that having a chart valid for 12 months is possibly too long if some pilots are clearly not keeping them up-to-date?
I originally learned to fly in the UK and have since done quite a few hours in the US. At first I hated the flimsy non-laminated charts and yearned for CAA-style ones, but having flown my last 60 or 70 hours 'over there', I now know which ones I'd choose. Don't want to start a UK/US debate, and yes, our charts are better in many ways, but would it be better to have cheaper paper charts which could be thrown away and replaced with crisp new up-to-date ones every 3 months? They're easier to fold (and smaller to handle), easier to write on (both day-to-day and when updates ARE required) and just, well... easier all around. OK, there's probably a cost issue (as usual with UK GA) as theirs probably outsell ours ba a factor of may 100:1, but... well... just an idea.
