VFR (Visual Flight Rules) pilots navigate primarily through pilotage and dead reckoning, using their eyes to reference landmarks on the ground. "Pilotage" involves comparing a specialized aeronautical chart (Sectional Chart) to physical features like highways, lakes, mountains, and distinct buildings. "Dead reckoning" involves calculating a flight path based on a known starting point, groundspeed, and compass heading. In 2026, while the "see-and-avoid" principle remains the legal foundation of VFR, almost all pilots supplement traditional skills with Electronic Flight Bags (EFBs) like ForeFlight on an iPad, which provides a "moving map" GPS position overlay. VFR pilots must also adhere to strict "Visual Meteorological Conditions" (VMC), which generally require at least 3 miles of visibility and a minimum distance from clouds (usually 500 feet below, 1,000 feet above, and 2,000 feet horizontally) to ensure they can safely see other aircraft and terrain. If weather conditions drop below these minimums, a VFR pilot is legally required to stay on the ground or land immediately at the nearest suitable airport.
