What does the ‘C’ in ‘VFR’ stand for?

The 'C' in 'VFR' stands for 'Visual.' VFR, or Visual Flight Rules, refers to 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 primarily responsible for maintaining visual reference to the ground and avoiding obstacles. This type of flight rules is essential for pilots as it requires them to operate in conditions that allow for visual navigation rather than relying solely on instruments.

In contrast, the other terms do not accurately define what VFR represents. 'Controlled' implies a level of air traffic control oversight that does not specifically describe the visual aspect. 'Cruising' relates more to the flight phase of an aircraft rather than the rules themselves, and 'Clear' does not capture the essence of visual navigation required under VFR. Thus, 'Visual' is the accurate term, highlighting the importance of seeing and navigating based on visual cues during flight.
