What does VFR mean?

• A. Visual Flight Rules; Rules that govern the procedures for conducting ground operations.
• B. Visual Flight Rules; Rules that govern the procedures for conducting flight by visual means.
• C. Visual Frames Rules; Rules that govern the procedures for instrument flight.
• D. Visual Flight Rules; Rules that govern the procedures for conducting instrument flight.

Answer: (D)

Visual Flight Rules means operating the aircraft by visual references outside the cockpit. In VFR you fly by sight, use see-and-avoid for other traffic, and rely on weather conditions that allow you to navigate visually. The wording that describes rules for conducting flight by visual means matches this exactly. The idea of conducting flight by instruments corresponds to IFR, not VFR, which is why the other phrasing isn’t correct.
