FAA Aircraft Dispatcher Practice Exam

What defines the visibility conditions for VFR pilots?

1. At least 3 miles visibility

2. Less than 3 miles visibility

3. Intermediate visibility of 2 miles

4. Only allowable during daylight hours

The correct answer is: At least 3 miles visibility

The visibility conditions that define VFR (Visual Flight Rules) pilots are primarily based on the requirement of maintaining a minimum visibility of at least 3 statute miles. This regulation ensures that pilots have sufficient visual references to navigate and avoid obstacles, other aircraft, and to maintain safe separation from the terrain. Under VFR, pilots are expected to operate in conditions where they can see and avoid other traffic and obstacles. Having a visibility of at least 3 miles allows pilots to maintain situational awareness and evaluate weather conditions effectively, providing a margin of safety necessary for flight operations under visual rules. Conditions less than 3 miles can present challenges for VFR operations, making it difficult for pilots to maintain adequate visual references. Furthermore, limiting operations to daylight hours is not a requirement solely defined by visibility but encompasses additional regulations regarding lighting and flight operations at night, which are separate from the visibility criteria. The mention of "intermediate visibility of 2 miles" does not align with the foundational requirements for VFR as defined by FAA regulations.
