1:500,000 or 1:250,000 VFR Charts
This may sound like a stupid question but i've reached a point during my PPL after a few lessons whereby i'm looking at buying a few bits and pieces which i'm going to need at some point during the course.
I'm taking lessons in and around London and was wondering what VFR charts would be preferable when flying in this area, whether it be 1:500,000 or 1:250,000.
