Final answer:
In aviation, three portions of the aircraft must be avoided: planes at the same altitude, planes 2,000 feet above, and planes 2,000 feet below. These regulations ensure safety and prevent collisions between aircraft. The restrictions on aircraft locations in aviation are similar to those on electron locations in quantum mechanics.
Step-by-step explanation:
In aviation, there are three portions of the aircraft that must be avoided to ensure safety: other planes flying at the same altitude, planes flying 2,000 feet above, and planes flying 2,000 feet below.
These regulations are set by the Federal Aviation Administration to maintain a safe distance between aircraft to prevent collisions. For example, planes are required to maintain a distance of five miles from each other when flying at the same altitude.
These regulations are similar to the restrictions on electron locations in quantum mechanics, where electrons are restricted to certain positions within an atom.
