What is the primary focus of VFR weather requirements?

The primary focus of VFR (Visual Flight Rules) weather requirements is on visibility and cloud ceiling. Under VFR, pilots must operate in weather conditions that allow for visual navigation. This includes maintaining a specific visibility level, which ensures that pilots can see other aircraft, the ground, and navigational landmarks to safely operate the aircraft.

The importance of cloud ceiling is also critical, as it determines the minimum altitude at which a pilot can fly while still being considered VFR. A cloud ceiling that is too low can limit visibility and prevent pilots from flying safely and effectively, especially in mountainous or terrain-rich areas. Therefore, the combination of adequate visibility and a high enough cloud ceiling is essential for flying under VFR conditions, ensuring that pilots can navigate visually without reliance on instruments.
