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

The term 'VFR' stands for Visual Flight Rules, which 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. In VFR conditions, pilots rely on visual references outside the cockpit, rather than instruments, to navigate. This is crucial for maintaining situational awareness and ensuring safe aircraft operation.

Understanding VFR is essential for pilots since these conditions dictate the way they plan and execute flight navigations. They must be aware of visibility requirements and cloud clearance to legally fly under VFR. This concept contrasts with Instrument Flight Rules (IFR), where pilots primarily depend on instruments to fly in less favorable weather conditions.

While the other options contain terms that may seem plausible in an aviation context, they do not accurately represent the established terminology used within the field.
