What is the minimum visibility requirement for Class C airspace?

In Class C airspace, the minimum visibility requirement is set at 3 statute miles (SM). This requirement ensures that pilots maintain sufficient visual reference to the ground and other aircraft while operating in more congested airspace where air traffic control services are provided. The rationale behind the 3 SM visibility requirement is to enhance safety by ensuring pilots can adequately see and avoid other aircraft as well as navigate effectively.

While other visibility requirements might exist for different airspace classifications, in Class C airspace, the emphasis on maintaining a 3 SM visibility is critical given the increased traffic and potential complexity of operations. This aligns with regulatory standards meant to promote safety and effective communication between pilots and air traffic control.
