How might carburetor icing impact engine performance?

• A. Decreased oil pressure
• B. Increased fuel efficiency
• C. Rough engine operation
• D. Improved throttle response

Answer: (C)

Carburetor icing occurs when moisture in the air freezes within the carburetor, restricting airflow and disrupting the proper mixing of air and fuel. This interference leads to an improper fuel-to-air ratio, which can cause the engine to run roughly. The rough engine operation manifests as fluctuations in power output, potential stumbling or hesitation during acceleration, and overall instability in the engine's performance. When conditions are right for carburetor icing, typically in cold, humid weather, pilots need to be aware that their aircraft may not perform as expected, and addressing this issue becomes crucial to maintaining engine reliability and safety.
