Visual Flight Rules (VFR) navigation relies on visual references, so it depends on visibility adequate for the pilot to identify those references.

### Why this is right Visual Flight Rules (VFR) navigation uses visible features on the ground to help determine position and direction. If visibility prevents the pilot from identifying those features, the central basis of pilotage is unavailable. ### The concept A visual reference may be a town, river, shoreline, road, or other recognizable feature. Visual Meteorological Conditions (VMC) describe weather conditions that permit flight using the applicable visual rules. Instrument Flight Rules (IFR), by contrast, use cockpit instruments as the basis for navigation and can support operations in lower visibility when requirements are met. The flight rules and actual weather conditions are related, but they are not interchangeable terms. ### Terms - **Visual Flight Rules (VFR)**: flight rules under which pilots navigate using visual references and must meet applicable visibility requirements. - **Visual Meteorological Conditions (VMC)**: weather conditions in which required visual flight conditions are met. - **Instrument Flight Rules (IFR)**: flight rules under which navigation relies on cockpit instruments and applicable procedures. ### Remember Pilotage needs identifiable ground features; instrument navigation uses instruments and procedures instead.
