Haze impacts visibility for pilots primarily by scattering light, which leads to a reduction in the clarity and distance at which objects can be seen. This scattering occurs because haze consists of tiny particles and water droplets in the atmosphere that interact with light. When light encounters these particles, it gets diffused in various directions rather than traveling straight to the observer's eye. As a result, distant objects appear blurred or less distinct, making it difficult for pilots to gauge distances accurately and leading to challenges in navigation and situational awareness during flight.

A clear understanding of haze is crucial for pilots, as visibility is a critical factor for safe flying, particularly during takeoff, landing, and in-flight maneuvers. Situational awareness can diminish significantly in hazy conditions, emphasizing the need for pilots to be vigilant and rely on instruments for navigation when visibility is compromised.
