In hazy conditions, how are traffic or terrain features perceived?

• A. As closer than they really are
• B. As farther away than their actual distance
• C. As the same distance as in clear air
• D. As blurred but with accurate distance

Answer: (B)

In hazy conditions, depth cues are reduced because haze scatters light and lowers contrast. Our ability to judge distance relies on cues like sharp edges, texture, shadows, and how objects fade with distance (atmospheric perspective). When those cues are diminished, the brain tends to interpret features as being farther away to account for the lack of detail and contrast.

So traffic or terrain features often appear farther away than they actually are. This misperception can affect timing and spacing, which is important for safe glider operation during approaches or when deciding to turn or descend.

The other options don’t fit because haze doesn’t typically make objects seem closer, nor does it preserve distance as in clear air, nor does it keep distance perception accurate when the scene is blurred.
