What are the speed restrictions in Class B airspace above 10,000 feet?

In Class B airspace, the primary objective is to ensure the safety and separation of aircraft, particularly around busy airports. Above 10,000 feet, there are no specific speed restrictions imposed within Class B airspace. This means aircraft operating at or above this altitude can exceed the typical speed limits that apply to driving through lower airspace, such as the 250 knots restriction below 10,000 feet.

While Class B airspace has regulations and requirements primarily focused on managing traffic and maintaining safe distances between aircraft, the absence of speed restrictions above 10,000 feet allows for more flexibility in flight operations. It is important to note that regardless of the lack of specific restrictions in Class B airspace, aircraft must still adhere to overall regulations that apply at higher altitudes, including any applicable maximum speed limits defined in other airspace classifications, as well as the considerations related to the vicinity of other airspace types that may still impose restrictions.
