What is the visibility requirement in Class C airspace?

In Class C airspace, the visibility requirement is indeed 3 statute miles. This is important for ensuring that pilots can navigate and maintain visual separation from other aircraft effectively. In Class C airspace, which typically surrounds busy airports with a significant amount of air traffic, maintaining this level of visibility allows pilots to see and avoid other aircraft, as well as terrain and obstacles.

The overarching purpose of the visibility requirement is to promote safety by ensuring that flight operations occur in an environment where pilots can adequately see and respond to changing conditions. This is especially crucial given that Class C airspace is characterized by a mix of commercial and private air traffic.

The other visibility options do not align with the regulations governing Class C airspace. Lower visibility requirements, such as 1 mile, may apply to certain other airspace classifications but are not sufficient for the more complex traffic environment found in Class C. Higher visibility requirements, like 5 or 10 miles, exceed what is necessary for Class C operations. The regulation effectively balances safety and efficiency in busy airspace.
