What is the altitude range typically associated with Class B airspace?

The correct choice indicates that Class B airspace extends from the surface up to airspace designated limits, which is accurate because Class B airspace typically encompasses a volume of airspace that is tailored for busy airports. The specific upper limit can vary between different Class B airspaces but is generally between 10,000 feet and 12,000 feet above sea level, depending on the airport and surrounding flight operations.

This designation provides safe separation between aircraft operating at lower altitudes and those operating at higher altitudes in busy terminal areas, ensuring that air traffic can flow smoothly in and out of high-traffic airports. The varying vertical limits are also frequently influenced by the surrounding airspace and geographical features, which is why it is critical to refer to sectional charts or the appropriate aeronautical publications for the specific Class B airspace under consideration.

Other choices specify rigid altitudes or ranges that do not accurately represent the true nature of Class B airspace. Class B is not limited to heights like 10,000 feet or set surfaces up to fixed altitudes. The complexity and variability of Class B airspace configurations necessitate a broader range definition that accommodates different airport operational needs.
