What are speed limits in class B and under class B?

• A. In Class B - 250 knots; Under - 200 knots
• B. In Class B - 300 knots; Under - 250 knots
• C. In Class B - 200 knots; Under - 180 knots
• D. In Class B - 320 knots; Under - 230 knots

Answer: (A)

Speed management in controlled airspace is all about keeping traffic flowing safely and predictably. In Class B, where air traffic is dense and closely sequenced around busy airports, the maximum allowable airspeed is 250 knots to maintain precise maneuvering and timely separation. In the airspace beneath Class B, where surrounding traffic blends and aircraft are transitioning to or from the Class B environment, the limit is lower—200 knots—to reduce wake turbulence effects and give ATC space to manage entry and exit without abrupt changes in speed. This pairing of limits helps balance efficiency with safety as flights move between the busy core of Class B and the surrounding airspace.
