I hold an FAA Part 107 certification, but probably like many who also went through this training, I'm still a bit confused about the complexity of Class B airspaces.
Here's an example...
I was asked to get a few aerial establishing shots of facility near Pittsburgh. Looking at the charts for KPIT, the building is clearly in a Class B airspace. The Airmap app, which I also use as a reference, also shows this.
However, I noticed recently that the Airmap app now show more "sections" of airspace (when you choose FAA Part 107 as a mission rule). Meaning, it just doesn't show one shape for an airspace, but rather multiple shapes that make up the whole. Each of those shapes appears to have it's own set of rules for safe flying height.
Look at figure 1. The red dot is obviously in a no fly zone, and the warning box shows that FAA authorization is required for any flight.
Now in figure 2, the red dot is in an area of the Class B where it appears that safe flying is possible below 100 feet.
And in figure 3, the red dot is in an outer area of the Class B where it appears 400 feet is the limit.
Now I realize that the Airmap app isn't an official source of information, but it can be interpreted that when flying in figure 2 and 3, you are able to fly provided you stay under the area's height limit.
Of course, I don't believe this to be true, but if it's not, why would Airmap assign height limits to the various sections of a Class B airspace? Are these numbers and complex section grids coming from the FAA? Is this the first step to let us fly more freely in such a controlled airspace?
The part I find confusing is if you look at the "official" VFR chart for KPIT, all these areas I pointed out in figures 1, 2, and 3 are in the SFC/80 (surface to 8,000 feet) no fly zone (Class B area A).
