"A very simple and cost effective system indeed!"
It is you are correct.
I was wondering however whether in fact it achieves the objective intended.
An analogy. Speed cameras are very cost effective. Do they actually reduce accidents caused by undue speed?
Presumably a copy of these publications could be sent to every current pilot. Would that be more cost effective in terms of the enhanced safety in might achieve if that is your primary objective?
Is it a good thing to rely on pilots passing the material on to other members of their group, pilots who might rent their aircraft or pilots who habitually rent from fly clubs?
