In aviation, what does VFR stand for?

VFR stands for Visual Flight Rules, which is a set of regulations under which a pilot operates an aircraft in weather conditions generally clear enough to allow the pilot to see where the aircraft is going. Pilots flying under VFR are responsible for maintaining separation from obstacles and other aircraft, as they rely on visual references rather than instruments for navigation. This is crucial for safety and situational awareness, allowing pilots to navigate and manage their flight without solely relying on instruments. Understanding VFR is essential for pilots as it affects their planning and decision-making processes during flight operations.
