What is the speed limit in class B airspace?

• A. 200 KIAS
• B. 300 KIAS
• C. 180 KIAS
• D. 250 KIAS

Answer: (D)

In Class B airspace, you must not exceed 250 knots indicated airspeed. This limit applies throughout the Class B from the surface up to its upper boundary, regardless of how high you are within that airspace. Using indicated airspeed keeps the limit consistent across different altitudes and temperatures, since true airspeed can vary a lot with altitude while the structural and maneuvering limits the airspace is designed to accommodate depend on IAS. Keeping below 250 KIAS helps maintain safe separation and predictable handling for the dense traffic around busy airports. The other speeds listed aren’t the standard Class B limit, which is why 250 KIAS is the correct constraint.
