Quick question (apologies if it's already answered elsewhere, but I couldn't find it....)
For some airfields (E.g. Nottingham) if I zoom in on the chart I get a detailed airfield plate, but for others (e.g. Caernarfon) it's just the runways (and unless I imagined it, the chart zoomed in automatically when I landed at Nottingham, which was nice).  What's the rationale for which airfields have which?  From what I can tell, through the custom data creator I can only create the basic version.

I think it was the latter that I was seeing - a very helpful addition - a bit more elegant that popping open the AIP plate (I've not got Pooley's/AFE subscription).
I assume there's no way to upload my own vector diagram for an unlicenced airfield?
