What is the weather minimum for a VFR flight in a control zone?

For a VFR flight conducted within a control zone, the minimum visibility requirement is indeed 3 statute miles, along with the requirement to maintain a distance of at least 1 mile horizontally from clouds. These standards ensure that pilots have sufficient visibility to navigate safely and avoid obstacles or other aircraft while remaining in controlled airspace.

Maintaining these weather minimums is crucial as they help prevent flight into situations with reduced visibility, which can lead to hazardous conditions, especially in busy areas where control and separation of aircraft are paramount. Thus, understanding and adhering to these requirements is essential for piloting safely under VFR in controlled airspaces.
