I'm a little unclear as to how the new geo-referenced plates function works, exactly. Do you have to have the paid-for Pooleys or AFE plates? At present, all I can get to work is the original very basic inbuilt plate, with no geo-referencing on the national AIP charts that I normally use. Am I missing something?

Yes but there are very few that show circuit and VRP information on a plate. Just having a georeferenced diagram of the airfield layout isn't that much help. The lack of local area detail has always been a limitation for me with Pooleys which is why I have always preferred the Jepperson VFR plates.

Clearly the limitations of Pooleys is not your problem but it would be nice to have access to plates with more local area detail that can be integrated into SD.
