Final answer:
Recreational drone flying is limited to 400 feet above ground level in uncontrolled airspace, as regulated by the Federal Aviation Administration to prevent possible collisions with manned aircraft.
Step-by-step explanation:
The flight path of a commercial airliner is meticulously controlled by the Federal Aviation Administration (FAA). To ensure safety and prevent collisions, the FAA mandates that airplanes maintain a minimum distance from each other, that is, five miles horizontally at the same altitude and 2,000 feet vertically above and below another aircraft, or 1,000 feet if flying below 29,000 feet altitude.
But the student's question pertains to recreational drone flying, which is governed by a different set of rules. For recreational drone flying, the FAA restricts flights to 400 feet above ground level in uncontrolled airspace unless you have specific authorization to fly higher. This limitation is part of the regulations to ensure the safety of both manned aircraft and unmanned aircraft systems by preventing the possibility of collisions.
