Which of the following describes a potential hazard caused by turbulence?

• A. Increased fuel efficiency
• B. Difficulty in maintaining a steady altitude
• C. Enhanced visibility
• D. Reduced engine noise

Answer: (B)

The selection of difficulty in maintaining a steady altitude accurately highlights a significant impact of turbulence on aircraft performance. Turbulence refers to the irregular and often violent disturbances in airflow that can result from various atmospheric conditions, such as weather fronts, thunderstorms, or even terrain. When an aircraft encounters turbulence, it can experience sudden changes in vertical speed and direction, making it challenging for pilots to keep the aircraft at a constant altitude. This can lead to fluctuations in altitude, which requires constant adjustments by the flight crew to stabilize the aircraft.

The other options do not represent hazards associated with turbulence. For instance, increased fuel efficiency is generally not a consequence of turbulence; in fact, flying through turbulent air can lead to increased drag and potentially lower fuel efficiency. Similarly, enhanced visibility is not a trait of turbulence; in fact, turbulent conditions can often coincide with reduced visibility due to precipitation or cloud developments. Lastly, reduced engine noise is not a relevant factor here; turbulence does not directly influence engine noise levels in a way that would be considered a safety hazard. Therefore, the correct answer emphasizes the challenges pilots face in maintaining stable flight during turbulent conditions.
