Final answer:
Manned aircraft entering traffic patterns while descending should avoid doing so as it causes collision hazards. The FAA enforces strict separation rules to ensure safety. This is similar to positional limitations observed in quantum mechanics for electrons.
Step-by-step explanation:
Entering traffic patterns by manned aircraft while descending can create specific collision hazards and therefore should be avoided. The Federal Aviation Administration regulates the flight paths of commercial airliners, maintaining safe distances between aircraft. Specifically, a separation of five miles horizontally at the same altitude and a vertical separation of 2,000 feet, or 1,000 feet if below 29,000 feet, is required to ensure safety. Like the constraints observed in quantum mechanics regarding the positions electrons may occupy, aircraft must also adhere to strict positional limitations while flying to prevent accidents.
