What does "VFR" stand for in aviation?

"VFR" stands for Visual Flight Rules, which are 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. Under VFR, pilots are responsible for maintaining visual separation from other aircraft and avoiding obstacles, which is essential for safe flight navigation.

This term is critical in aviation because it guides pilots on how to operate in a way that allows them to rely on their own vision for navigation, rather than solely relying on instruments. VFR conditions typically suggest good weather, where the pilot can see and avoid other aircraft and terrain, thus enhancing safety.

The other choices might sound plausible at a glance but do not accurately represent established aviation terminology. Understanding VFR is essential for flight planning and operations, as it delineates the guidelines under which a pilot can fly visually.
