What is the maximum indicated airspeed authorized in the airspace underlying Class B airspace?

In the airspace underlying Class B airspace, the maximum indicated airspeed authorized is 200 knots. This regulation is designed to ensure safety and orderly operations around busy airports where Class B airspace is established. By limiting the airspeed, the intent is to minimize the risk of wake turbulence and to allow for more controlled traffic flow. The speed limit is particularly important given the high volume of commercial air traffic typically present in and around Class B airspace, which is usually associated with major metropolitan airports.

In addition to safety considerations, this regulatory standard helps maintain a standardized operational environment for both pilots in general aviation and flight operations involving commercial airliners. Being aware of and adhering to these speed limitations is essential for pilots to operate safely within controlled airspace, ensuring both compliance with regulations and the safety of all air traffic.
