Fog
Definition
A cloud at ground level that reduces visibility below 1 kilometer. Types include radiation fog (nighttime cooling), advection fog (warm air over cold surface), and upslope fog. A major cause of IFR conditions.
Why Fog Matters for Pilots
Weather concepts like Fog appear frequently on both FAA and EASA knowledge exams. More importantly, understanding Fog helps pilots make sound go/no-go decisions and avoid hazardous conditions in flight. Weather-related accidents remain a leading cause of general aviation incidents.
Exam Tip
This concept is commonly tested in meteorology-related questions on FAA and EASA exams. Make sure you can explain Fog in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
