Final answer:
In most areas, the Class E airspace base is 1,200 feet AGL, whereas in other areas, it can be surface level or 700 feet AGL. Aircraft must maintain specific horizontal and vertical separations for safety, similar to electron position restrictions in quantum mechanics.
Step-by-step explanation:
In most areas, the Class E airspace base is 1,200 feet above ground level (AGL). In many other areas, the Class E airspace base is either the surface or 700 feet AGL.
The airspace system is designed to maintain a safe distance between aircraft; for example, each airplane must maintain a distance of five miles from another plane at the same altitude and a vertical separation of 2,000 feet above and below another aircraft, which changes to 1,000 feet if the altitude is less than 29,000 feet, thereby ensuring aviation safety.
This regulation of airspace is analogous to the restrictions on the locations of electrons as explained by quantum mechanics.
