You already know this, but I just found out about the Notam layer option, in Maps view. (why didn’t you tell me?) screenshots: 1. Only TFRs shown (how I used to always display Maps) 2. Notams layer selected (tons of previously unnoticed sua, mostly UAVs it seems) 3. Quick tap of one of these shows a bit of detail. What is the practical difference of a drone having a tfr vs one having a notam? (A parently atc wants us staying out of both although they gave leniency on one around my destination). AIM reference?
