What is the maximum speed allowed in Class B airspace?

In Class B airspace, the maximum indicated airspeed for aircraft is primarily set to facilitate safe and orderly traffic flow around busy airports. The designated maximum speed within Class B airspace is 250 knots. This regulation is crucial because Class B airspace surrounds major airports that often see significant air traffic, including both commercial and private aircraft. Maintaining a lower speed helps control the flow of aircraft, reducing the risk of collisions and enhancing overall safety in an environment where pilots are operating in close proximity to one another.

While other airspace classifications impose different speed limits depending on altitude and other factors—such as 200 knots below 2,500 feet in some airspace and 250 knots below 10,000 feet—these limits are either more restrictive in certain areas or do not apply directly to the specific scope of Class B airspace. In summary, the 250-knot maximum speed is established as a necessary operational standard within Class B airspace to ensure safety and efficiency in air traffic management.
