What is the speed limit below 3,000 feet AGL within 10 nautical miles of a controlled airport?

The correct answer is based on the regulatory framework that governs airspace and vehicles operating in proximity to controlled airports. Under the Federal Aviation Regulations (FAR), the speed limit below 3,000 feet above ground level (AGL) within 10 nautical miles of a controlled airport is set at 200 knots indicated airspeed (IAS).

This regulation is in place to ensure safe and orderly operations in high-traffic areas around airports. These limits help to maintain a manageable flow of incoming and outgoing aircraft, reducing the risk of mid-air collisions and enhancing the safety of both IFR and VFR operations in congested environments. The choice of 200 knots IAS is a specific measure taken by aviation authorities to balance operational needs with safety concerns.

Understanding these regulations is crucial for pilots, as adherence not only promotes safety but also compliance with national and international aviation standards.
