Final answer:
Aircraft flights are regulated to avoid collisions by maintaining specified distances, akin to the positional restrictions found in quantum mechanics, while rules in aviation can impact opportunity access but aim to serve functional purposes.
Step-by-step explanation:
The flight path of a commercial airliner is strictly controlled by the Federal Aviation Administration (FAA) to prevent collisions in the sky. These regulations ensure that each aircraft maintains a safe distance from other aircraft, both laterally and vertically. Specifically, airplanes are required to keep a distance of five miles from another plane at the same altitude and a vertical separation of 2,000 feet from an aircraft flying at different altitudes (or 1,000 feet if below 29,000 feet). Quantum mechanics similarly restricts the positions of electrons, illustrating a principle of limited availability of states.
Rules in aviation, such as the minimum and maximum height requirements for Air Force pilots, though appearing neutral, can have significant impacts on who can access certain opportunities. However, these rules, just like those governing aircraft separation, serve specific functional purposes, such as fitting pilots properly into their seats.
