What am I still able to use after I cancel the monthly subscription? If I understand it correctly, I’ll be able to use the charts I have at that moment. Can I still view them in the Windows Charts app?
Can I also continu using SimLink / MSFS moving map with those (out of date) charts?
The only thing you can keep is any downloaded FMS Data/navdata files on your local machine.
Access to Charts is completely revoked after your subscription ends. You will not have access to old or expired charts, only the 2 demo airports (NZWN and YBBN) will be accessible. This goes for all Charts apps including iPad and Android.
