What is the maximum indicated airspeed for operating an aircraft below 10,000 feet MSL unless otherwise authorized?

1. 200 knots

2. 250 knots

3. 220 knots

4. 180 knots

The correct answer is: 250 knots

The maximum indicated airspeed for operating an aircraft below 10,000 feet MSL, unless otherwise authorized, is 250 knots. This regulation is established to maintain a safe operating environment and to minimize the risk of mid-air collisions, particularly in busy airspace around airports and in areas where lower altitude operations are common. In the U.S., the Federal Aviation Administration (FAA) has set this speed limit to ensure that aircraft are operating within a manageable speed range, which is particularly important in the presence of slower-moving general aviation aircraft and during flight operations close to crowded airspace. By adhering to this limit, pilots can contribute to a safer flying environment and easier traffic management for air traffic controllers. Furthermore, operating at or below 250 knots helps prevent the onset of aerodynamic issues that could arise at higher speeds, especially in aircraft that may not be designed for high-speed operations at lower altitudes. Understanding this regulation is crucial for pilots to ensure compliance and safety during their flights.
