My original point was that the 'Terminal Procedure Publications' seemed a good idea.
Their format seems more suited to GA.
They are readily available and they are reasonably priced, at less than 6 dollars per region.
Jeppessen etc charts are fine products, if you use them on a daily basis.
But the price seems difficult to justify for a mere IMCR GA pilot, where as the 'Terminal Procedure Publications' approach seems more suitable.
