What does the acronym VFR stand for in aviation?

The acronym VFR stands for Visual Flight Rules. This term is essential in aviation as it 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. Under VFR, pilots are responsible for maintaining visual separation from obstacles and other aircraft, navigating by visual references, and adhering to certain altitudes and requirements as dictated by aviation regulations. This contrasts with IFR, or Instrument Flight Rules, where pilots rely on instruments for navigation and control when visibility is limited. Understanding VFR is crucial for pilots as it outlines operational guidelines and safety measures under which they can safely conduct flight operations.
