hello, I've download a lot of Jeppensen SID, STAR VOR approach, NDB apporach and airport charts but how to read them? Is there a website with reading material in how to read aviation charts?

It takes time to learn what all those things mean. I had to take an instrument ground school and spend a lot of time studying them before I figured out what all the possible info meant.Here's a link to a Computer Pilot article that's available online that should help. It's a PDF file, BTW.http://www.computerpilot.com/files/V5I6-aoif.pdf
