Does this make sense and can it be done?
By the way vertical nav feature was extremely helpful yesterday. Low and varying cloudbase .. could pick my way through low ground with ease. Great.

Around larger airports, there are abutting airpsaces that have different height restrictions.
If you get appropriate clearance from say Doncaster at 3000', that will inlcude all the airspace around Doncaster.
But you can come in at <1500' and then you are only worried about the airspace that starts further in at ground level.
My point was that if you have permission to cross at 3000' then its effectively all 1 airpsace and you dont need alerts and entry/exit messages as you approach/cross the 2d boundaries.
Any clearer?
