FAA Ground School Practice Test

What is the maximum indicated airspeed allowed for aircraft flown at or below 2500 feet AGL and within 4 nautical miles of the primary airport of Class C airspace?

1. 250 knots

2. 200 knots

3. 220 knots

4. 180 knots

The correct answer is: 200 knots

The maximum indicated airspeed allowed for aircraft operating at or below 2,500 feet AGL (Above Ground Level) and within 4 nautical miles of the primary airport of Class C airspace is 200 knots. This regulation exists to ensure safety and reduce the potential for conflicts with other aircraft, particularly in congested airspace around major airports. Flying at this speed helps maintain better spatial awareness and control, allowing pilots to more effectively manage their aircraft's performance when maneuvering in busy areas. The restriction to 200 knots at lower altitudes and close proximity to airports facilitates smoother traffic flow and promotes compliance with established air traffic control procedures. Understanding this speed limit is critical for pilots, particularly when transitioning through or operating near controlled airspace, as it contributes to overall air traffic safety and efficiency.
