What disadvantage is associated with a T-Tail design in aircraft?

• A. Increased drag at high speeds
• B. Sensitivity to deep stall conditions
• C. Limited maneuverability during turns
• D. Higher chances of engine failure

Answer: (B)

A T-Tail design in aircraft features a horizontal stabilizer mounted at the top of the vertical stabilizer, which can provide benefits in terms of aerodynamic efficiency and improved visibility from the cockpit. However, one significant disadvantage of this design is its sensitivity to deep stall conditions. In a deep stall scenario, the airflow over the horizontal stabilizer can become severely disrupted, which may lead to a loss of control because the stabilizer is positioned far above the airflow that is affected by the wings. This configuration can delay recovery efforts and make it challenging for the pilot to regain control. The lack of aerodynamic effectiveness in such a scenario can turn very critical, making T-Tail aircraft more prone to experiencing difficulties during a stall recovery. Considering the other options, increased drag at high speeds does not specifically relate to the T-Tail design's primary characteristics. Limited maneuverability during turns may be influenced by other factors, such as aircraft size and weight distribution, rather than the T-Tail configuration itself. Lastly, while any aircraft can face risks related to engine failures, a T-Tail design does not inherently increase those chances; engine reliability is often related to maintenance and design choices unrelated to tail configuration.
