What effect does ice accumulation have on an aircraft's performance?

• A. Increases lift
• B. Decreases drag
• C. Increases fuel consumption
• D. Decreases stalling speed

Answer: (C)

Ice accumulation on an aircraft negatively impacts its performance primarily by increasing fuel consumption. When ice forms on the wings and control surfaces, it alters the aircraft's aerodynamics. This results in a higher drag coefficient, meaning the engines must work harder to maintain speed and altitude, leading to increased fuel consumption. Additionally, ice accumulation disrupts the smooth airflow over the wings, reducing overall efficiency. Pilots may also have to adjust power settings to compensate for the reduced aerodynamic performance, which further contributes to higher fuel usage. This concept highlights the importance of de-icing and anti-icing procedures in aviation to ensure safe operation and optimal performance when flying in conditions that are conducive to ice formation.
