Visual Flight Rules (VFR) are 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 must maintain visual reference to the ground and other landmarks, ensuring they can navigate safely without relying solely on instruments. Under VFR, pilots are responsible for avoiding obstacles and other aircraft. They must also adhere to specific altitude and distance requirements from clouds. These rules help ensure safety in the skies, especially in good weather conditions, allowing pilots to enjoy the experience of flying visually.
