Which of the following is an advantage of an all-moving incidence tailplane?

• A. Reduced drag at low speeds
• B. Higher maximum speed
• C. Larger CG range
• D. Lower maintenance costs

Answer: (C)

An all-moving incidence tailplane, often referred to as a canard or stabilator, contributes significantly to enhancing the aircraft's stability and control characteristics. One of the primary advantages of this design is the ability to achieve a larger center of gravity (CG) range. This advantage arises because the all-moving tailplane can adjust its angle of incidence in relation to the airflow over the aircraft. By doing so, it can provide greater pitch control authority without requiring substantial wing adjustments. Consequently, a larger CG range allows for more flexibility in aircraft design, enabling the positioning of payloads and fuel in a way that optimizes performance and stability. In addition, this feature can improve handling during various flight regimes, such as takeoff, cruising, and landing, making the aircraft more versatile in terms of weight distribution and load management. This adaptability is especially beneficial in ensuring safe and efficient flight operations across different operating conditions.
