What does "VFR" stand for in aviation terms?

"VFR" stands for Visual Flight Rules. This term is critical in aviation as it delineates a set of regulations under which a pilot operates an aircraft in visual meteorological conditions (VMC). Under VFR, pilots are required to maintain visual separation from terrain and other aircraft, relying on their ability to see outside the cockpit rather than on instruments.

VFR procedures are crucial for primarily visual navigation and operations, emphasizing the pilot's responsibility to navigate using visual references. This is in contrast to Instrument Flight Rules (IFR), where pilots navigate primarily by instruments due to poor visibility or other factors.

Understanding VFR is essential for pilots, as it impacts flight planning, altitude selection, and overall navigation strategy, especially in busy airspace where maintaining visual separation is key to safety. The other options do not accurately represent established aviation terminology.
