A degraded visual environment (DVE) is characterized by reduced visibility, which can occur due to various factors, such as fog, rain, snow, dust, smoke, or any other phenomenon that obscures visual reference points. In such conditions, pilots may struggle to maintain spatial orientation and navigate effectively, resulting in an increased risk of accidents.

When visibility is reduced, pilots rely heavily on their instruments and may face challenges with depth perception, object recognition, and situational awareness. Understanding the conditions that create a DVE is critical for ensuring safety in aviation operations, particularly in approaches and landings.

Visibility conditions that are high, normal visual cues, or clear atmospheric conditions do not contribute to a DVE; instead, they support safe flight operations and enhance situational awareness. Hence, recognizing reduced visibility as the defining characteristic of a degraded visual environment is essential for effective aeromedical practice and flight safety.
