Final answer:
CAR 602.73 requires pilots to file a VFR flight plan or itinerary for flights beyond a certain distance from the departure aerodrome to ensure safety and prevent collisions, akin to separation rules in quantum mechanics for electrons.
Step-by-step explanation:
The regulation cited, CAR 602.73, concerns the operations of aircraft under Visual Flight Rules (VFR). It requires that a pilot-in-command must file a VFR flight plan or a VFR flight itinerary for flights that are beyond a specific distance from the departure aerodrome. This is part of broader aviation safety regulations ensuring that airplanes do not collide during flight. To prevent collisions, commercial airliners are subject to strict separation standards overseen by the Federal Aviation Administration. These standards include maintaining a minimum horizontal distance of five miles from another airplane at the same altitude, and a vertical separation of 2,000 feet (or 1,000 feet if below 29,000 feet), which gives each aircraft certain positions it can maintain in the airspace. These rules are somewhat analogous to quantum mechanics rules that limit where electrons can be located around an atom.
