Class B airspace typically has airspeed restrictions up to what altitude?

Class B airspace is designed to manage high-density traffic around major airports, and it imposes specific airspeed restrictions to maintain safety and orderliness. The airspeed limit for aircraft operating within Class B airspace is typically set to 250 knots indicated airspeed (KIAS) at or below 10,000 feet MSL (Mean Sea Level). This restriction helps to minimize the potential for wake turbulence and allows for better separation of aircraft, particularly in busy terminal areas where operations may include both high-speed jets and slower general aviation aircraft.

Once an aircraft ascends above 10,000 feet, it is subjected to different airspace regulations, including higher allowable speeds, primarily to facilitate efficient en-route flight for jet traffic. Understanding these altitude thresholds and restrictions is crucial for maintaining safety in flight operations, especially in the vicinity of major airport hubs.
