What is the maximum airspeed in/under Class B airspace?

• A. No maximum in Class B; below 10,000 ft maximum is 250 knots; below Class B maximum is 200 knots
• B. There is no maximum speed anywhere
• C. The maximum in Class B is 300 knots at all altitudes
• D. The maximum in Class B is 200 knots at all altitudes

Answer: (A)

Within Class B airspace, you must not exceed 200 knots indicated airspeed. This applies regardless of altitude, because Class B is designed for high-density, high-traffic environments around busy airports and requires tighter speed control for safe sequencing of arrivals and departures. Outside Class B, the common limit is 250 knots below 10,000 feet MSL, so that rule still governs most other controlled airspace. The idea that there’s no maximum in Class B isn’t correct, since Class B has a specific speed limit to help manage traffic safely. So the key takeaway is: 200 knots in Class B at all altitudes; 250 knots below 10,000 feet outside Class B.
