What can pilots expect in terms of visibility when cloud cover is extensive?

• A. Increased visibility for navigation
• B. No effect on visibility
• C. Frequently obscured visibility
• D. Visibility is always enhanced

Answer: (C)

When cloud cover is extensive, pilots can expect frequently obscured visibility. Extensive cloud cover typically means a thick layer of clouds that can restrict how far one can see, especially in lower altitude situations or when flying through cloud layers. This reduction in visibility can pose challenges for navigation and situational awareness, as landmarks and environmental cues become obscured by the clouds.

The phenomenon of obscured visibility is especially critical during approaches and landings when pilots need to see the runway and surrounding area clearly. In addition, clouds can also be accompanied by precipitation, fog, and other atmospheric conditions that further reduce visibility. This makes understanding the effects of extensive cloud cover on visibility crucial for safe flight operations.
