Why should damper valves be kept closed during a maximum rate climb to altitude?

• A. To improve fuel efficiency
• B. To prevent excess air from being exhausted
• C. To increase the rate of ascent
• D. To avoid a higher rate of ascent

Answer: (D)

During a maximum rate climb to altitude, damper valves should be kept closed primarily to avoid a higher rate of ascent than desired. When damper valves are open, they allow for greater airflow, which can lead to increased lift and a faster rate of ascend that may not be controllable or optimal for the flight conditions. By keeping these valves closed, the aircraft maintains better control over the ascent rate, ensuring that it remains within safe operational limits. This control is crucial, particularly during climbing phases when the aircraft's performance and structural integrity are under greater stress. Additionally, managing the rate of ascent helps in maintaining proper engine performance and can prevent situations where the aircraft might exceed its design specifications. Maintaining a stable and controllable ascent is vital for safe flight operations, making the rationale for keeping the damper valves closed essential in this context.
