4. Airspace geometry

5. Airspace Altitudes
The airspaces are defined with horizontal boundaries and altitudes for upper limits, lower limits and minimum altitudes.

6. Derived Airspace Geometry
The airspace model includes two geometrical constructs:
Airspaces can be related by sharing the same horizontal borders.
Airspaces can be created by combining component airspaces through union ( addition), intersection and subtraction.
2+ airspace with same horizontal border
Airspace derived from aggregation of parts
