What is the maximum speed allowed below Class Bravo airspace?

The correct answer indicates that the maximum speed allowed below Class Bravo airspace is 250 knots indicated airspeed (KIAS). This speed restriction is in place to enhance safety, reduce noise, and minimize the risk of collision with slower-moving aircraft operating in the vicinity of busy airports. The 250 KIAS rule applies to all aircraft operating below the lateral limits of Class Bravo airspace, which extends from the surface up to a specified altitude, typically 10,000 feet above sea level in most airspace structures.

This regulation aligns with the Federal Aviation Administration (FAA) guidelines, which seek to promote an organized flow of traffic in and out of high-density airport areas. By setting this maximum speed, the FAA ensures that pilots maintain better control and situational awareness when flying in proximity to an airport, where higher traffic levels are common.

While other speed limits may apply in different airspaces or under specific conditions, the 250 KIAS limit is a key parameter for pilots to remember when operating beneath the boundaries of Class Bravo airspace. Understanding these limits is crucial for maintaining compliance with aviation regulations and ensuring the safety of flight operations.
