What does the term "VFR" stand for in aviation?

The term "VFR" stands for Visual Flight Rules. This 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. VFR enables pilots to fly by visual reference to the ground and the horizon, rather than relying solely on instruments. It is an important aspect of aviation as it provides the conditions under which VFR pilots can navigate and control their aircraft without needing to rely on air traffic control services as heavily, thus promoting safety in good visibility conditions.

Understanding VFR is crucial for pilots, especially in differentiating it from IFR (Instrument Flight Rules), which is used when visibility is poor and flight must be conducted primarily by reference to instruments.
