What do Visual Flight Rules (VFR) govern?

Visual Flight Rules (VFR) govern the operation of aircraft in weather conditions generally clear enough for pilots to see where the aircraft is going and avoid other obstacles or aircraft. Under VFR, pilots are responsible for maintaining visual separation and ensuring that they fly within certain visibility and cloud clearance criteria, which allows for safe navigation and flying primarily by visual reference.

The focus of VFR is on conditions that do not require reliance solely on instruments for navigation and control. Therefore, stating that VFR pertains to aircraft operations in clear weather is accurate, as it emphasizes the need for visual references that are only available when weather conditions are favorable.
