I prefer that all airspace’s are depicted. Say you are flying along and decide to descend to avoid weather, turbulence, etc. If the Class B, C, etc. airspace is not depicted, you may inadvertently pass into it without knowing.
Don, I saw your post on the tripltek. I have an iPad mini 5 now but do not like the visibility in direct sun or it over heating. Seems the tripltek does not have those problems. What do you use to mount it?
