I want to collate an A5 folder of charts from all the frequent airports I visit, just so I have a physical copy of the chart right in front of me. So I was wondering just how often Ground Charts, SID’s and STAR’s etc actually get updated? I mean its pointless me printing off 100’s of charts if they are going to be outdated every 2 or 3 cycles. I have a feeling they don’t really get changed all that often? And even if the odd one did get updated, it would be easy for me to see via Navigraph Charts.
