Visual obscuration refers to the phenomenon where an object or area becomes difficult to see due to various factors, such as fog, smoke, or other environmental conditions. This can significantly impact visibility, making it challenging for individuals to perceive their surroundings clearly. In aviation, visual obscuration is a critical concern, as it can affect pilots' ability to navigate safely. Instruments and technology, such as radar and GPS, are often used to compensate for reduced visibility caused by visual obscuration, ensuring safer travel in adverse conditions.
