As the pilot-in-command of an aircraft, what speed should you adjust to before entering Class B airspace?

Before entering Class B airspace, the appropriate action is to adjust your speed to not exceed 250 knots. This is a specific regulation outlined in the Federal Aviation Administration (FAA) guidelines to ensure safety and maintain orderly flow of air traffic within busy terminal areas. Class B airspace encompasses areas around major airports where air traffic is typically high, and maintaining a maximum speed helps reduce the risk of mid-air collisions and enhances communications with air traffic control.

The imposition of a 250-knot speed limit below 10,000 feet MSL (Mean Sea Level) is designed to manage the complexity that comes with increased traffic density and varied types of aircraft operating in that space. Knowing to adjust your speed accordingly is essential for compliance with FAA regulations and promotes a safer operating environment.
