What is the standard weather minimum for Class B airspace?

The standard weather minimum for Class B airspace requires pilots to have at least 3 statute miles of visibility and to remain clear of clouds. This regulation is designed to ensure that pilots operating in busy terminal airspace maintain a sufficient level of visual reference to avoid other aircraft and to be aware of their surroundings.

Maintaining this visibility and cloud-clear status is crucial for safety in Class B airspace, where a high density of air traffic exists, particularly around major airports. Pilots need to be able to see and identify other aircraft, navigate effectively, and adhere to the air traffic control instructions that are prevalent in these busy environments. This requirement reflects the need for enhanced situational awareness and the ability to respond quickly to changes in the traffic situation.
