Within Class C and D airspace, what is the minimum altitude and indicated airspeed requirement within 4 NM?

• A. No less than 2,500' AGL and 200 knots
• B. No less than 3,000' AGL and 180 knots
• C. No less than 1,500' AGL and 210 knots
• D. No less than 1,000' AGL and 190 knots

Answer: (A)

In the 4 NM zone around the primary airport in Class C and D airspace, you must stay at or above 2,500 feet above the surface and not exceed 200 knots indicated airspeed. This combination creates a safe, predictable environment near busy approaches and departures. The 2,500' AGL floor keeps you clear of lower traffic and wake turbulence from arriving or departing aircraft, while the 200-knot limit slows down operations to improve ATC sequencing and reduce risk as aircraft merge in the terminal area.
