What is the visibility requirement for controlled airspace at or below 1,200 feet AGL?

The visibility requirement for controlled airspace at or below 1,200 feet AGL is 3 statute miles. This is established to ensure that pilots have sufficient visual reference to navigate safely and avoid collision with other aircraft and obstacles. In controlled airspace, maintaining this level of visibility is crucial, as it complements the altitude rules and the weather criteria that must be adhered to during flight.

Visibility in this context is especially important for pilots navigating through lower altitudes, where they may encounter increased traffic and other visual obstructions. By requiring 3 statute miles of visibility, regulations help promote safer flying conditions and allow pilots to effectively gauge their surroundings.

Understanding these visibility requirements is essential for pilots operating in controlled airspace, as it directly relates to their ability to safely conduct operations and comply with airspace regulations.
