What is the minimum required visibility for VFR operations in controlled airspace?

The minimum required visibility for Visual Flight Rules (VFR) operations in controlled airspace is 3 statute miles. This requirement ensures that pilots have enough visibility to see and avoid other aircraft, as well as obstacles on the ground, while navigating and operating their aircraft. The 3 statute miles visibility helps maintain safety standards in controlled airspace, where more traffic can be present and maintaining visual reference to the surroundings is crucial for flight operations.

This visibility threshold is established according to aviation regulations, which are aimed at promoting safe flying conditions. In controlled airspace, where air traffic is managed more tightly, maintaining this level of visibility supports both pilot situational awareness and overall air traffic management.
