Final answer:
Haze can affect the ability to see traffic or terrain features during flight in several ways. The eyes may focus at infinity, making objects appear blurry, and it can be difficult to detect relative movement. Additionally, haze can make traffic or terrain features appear farther away than they actually are.
Step-by-step explanation:
Haze can have several effects on the ability to see traffic or terrain features during flight. Firstly, haze causes the eyes to focus at infinity, which means that objects at different distances may appear blurry or out of focus. Secondly, the eyes tend to overwork in haze, which makes it difficult to detect relative movement easily. This can make it challenging to perceive the speed and distance of other aircraft or objects. Lastly, haze can cause all traffic or terrain features to appear farther away than their actual distance due to scattering and diffraction of light by the haze particles.
