What is the primary visibility requirement for VFR operations in general airspace?

The primary visibility requirement for VFR (Visual Flight Rules) operations in general airspace is indeed 3 statute miles. This standard is set to ensure that pilots can see and avoid obstacles, other aircraft, and terrain while flying. Maintaining a visibility of at least 3 statute miles allows pilots to navigate and operate safely without relying solely on instruments, which is essential for VFR operations where visual cues are crucial. This requirement is part of the regulations stipulated by aviation authorities to ensure safety in flight operations under visual conditions.
