What is the minimum horizontal visibility requirement in Class C airspace?

In Class C airspace, the minimum horizontal visibility requirement is indeed 3 statute miles. This regulation is in place to ensure that pilots maintain a sufficient visual perspective of their surroundings, which is crucial for safe navigation and collision avoidance. The 3 statute miles of visibility allows pilots to clearly see and identify other aircraft, terrain, and any potential obstacles in their flight path.

This requirement aligns with the need for enhanced safety measures as Class C airspace is usually associated with busy airports where both VFR (Visual Flight Rules) and IFR (Instrument Flight Rules) operations coexist. The standard also ensures that pilots can effectively communicate and collaborate with air traffic control, which is essential in this environment to manage air traffic efficiently. Maintaining 3 miles of visibility is thus an important factor in ensuring the safety and operational integrity of flights in and around Class C airspace.
