What is the maximum altitude for Class B airspace?

The maximum altitude for Class B airspace is typically from the surface up to 10,000 feet mean sea level (MSL). This classification of airspace is designed to manage high-density flight operations around major airports, ensuring safety and efficient traffic flow. The structure of Class B airspace is tailored to accommodate the significant volume of commercial and general aviation traffic that can occur in urban areas, which often necessitates this altitude limit.

While there can be variations depending on local procedures, the standard maximum altitude for Class B airspace is indeed 10,000 feet MSL. This allows for a buffer between the dense air traffic below and other airspaces above, contributing to overall safety and organization in busy flight environments. Other altitudes provided in the choices do not reflect the commonly accepted limits for Class B airspace under FAA regulations.
