Why are the electronic charts so expensive though? I'm not saying they should be less expensive than paper charts but they miss out the printing process and if they are available for download there is no transport issues to think about.
To have a chart when flying is a legal requirement and I think they should be more freely available and easier to work with. Having electronic versions would allow easier and quicker updates to be made and would hopefully mean that you were safer.
I myself am put off by the high cost of the electronic charts, especially when you have to buy new ones every couple of years.
