What effect does haze have on the ability to see traffic or terrain features during flight?

Haze can significantly distort visual perception during flight, primarily by altering the way objects are perceived at a distance. When haze is present, the scattering of light contributes to an optical illusion where traffic or terrain features appear farther away than they actually are. This phenomenon can be attributed to the reduced contrast that haze creates, making it difficult for pilots to accurately judge distances.

In low-visibility conditions caused by haze, pilots may misinterpret how far away other aircraft or landmarks are, which can affect their situational awareness and decision-making. Such misunderstandings can have serious implications for safety, especially when it comes to maintaining safe separation from other aircraft and navigating terrain. Understanding this aspect of visibility is crucial for pilots, as it underscores the importance of relying on instruments rather than solely visual references when flying in poor visibility conditions.
