Several airports have no charts at all, while existing charts are available on-line, free of charge. I would like to have the possibility to add custom charts (either a link or a PDF) per airport that I use often, so that navigraph can be extended. Moreover, it could be done in a collaborative way so that charts additions could be shared by the community.
For instance, I take the example of LFLJ, no charts in navigraph while a nice one is published (all charts are published in france by authorities) on this web site Visualisateur AIP for instance
I could position the chart on the navigraph map so that we could also benefit of the overlay feature.
