What is the maximum indicated airspeed when operating below Class B airspace?

The maximum indicated airspeed when operating below Class B airspace is 200 knots. This regulation is in place to ensure safety and reduce the risk of conflicts with other aircraft, particularly those transitioning to and from busy airports in Class B airspace. Maintaining this speed limit allows pilots to have better maneuverability and control while navigating near areas with high traffic, where the risk of encountering other aircraft is elevated.

In U.S. airspace regulations, different speed limits are applied depending on the airspace classification, and Class B areas are considered among the busiest. Lowering the speed to 200 knots helps to facilitate a safer environment for both the pilot and other aircraft in the vicinity. This rule is crucial for effective communication and coordination between air traffic control and pilots flying in and around Class B airspace, further highlighting the importance of adhering to indicated speed limits in aviation safety protocols.
