Final answer:
The aircraft must maintain a specific distance from other planes to avoid collisions.
Step-by-step explanation:
The aircraft must be able to maintain a specific distance from other planes, as regulated by the Federal Aviation Administration. This includes maintaining a distance of five miles from another plane flying at the same altitude and being 2,000 feet above and below another aircraft (1,000 feet if the altitude is less than 29,000 feet).
For example, if an aircraft is flying at an altitude of 30,000 feet, it must be at least 2,000 feet above or below another aircraft at the same altitude. This ensures that there is enough separation between planes to avoid collisions.
By following these regulations, pilots and air traffic controllers can ensure the safety and efficiency of air travel, allowing multiple planes to fly without running into each other.
