All of these different area restrictions can be confusing to this newbie. To help me understand some of it I have an area I want to fly in and it looks to be a Class D area because of a nearby airport. Looking at the Airmap app it is showing a 400' limit but the warnings are saying I can only get automatic authorization below 200'. Flying a Mini2. Attaching a screenshot of the area. Can someone explain this to me? Thanks!
