What does the acronym "VFR" mean in aviation?

The acronym "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 navigate and control the aircraft by visual reference to the ground and other landmarks, rather than relying solely on instruments and air traffic control guidance.

Visual Flight Rules are crucial for pilots operating in good weather, as they permit flexibility and promote operational efficiency by allowing pilots to operate without the need for instrument navigation or communication with air traffic control, provided they are able to maintain visual separation from other aircraft and obstacles. Understanding VFR is essential for pilots as it helps ensure safety and proper navigation in visual conditions.
