What is the main result of having a T-Tail configuration?

The main result of having a T-Tail configuration is the decreased downwash effects on the stabilizer. In a T-Tail design, the horizontal stabilizer is positioned well above the airflow disturbance caused by the wings. This positioning minimizes the impact of downwash from the wings, allowing the horizontal stabilizer to maintain more effective lift even in various flight conditions.

This configuration is particularly advantageous during maneuvers that might otherwise cause the tail to experience turbulent airflow, which can degrade its performance. Additionally, by reducing the interaction between the wing and horizontal stabilizer, a T-Tail helps maintain better pitch control and stability.

While the other options highlight potential issues or effects related to aircraft design, they do not accurately reflect the primary benefit of a T-Tail setup, which is its ability to function effectively with minimal interference from wing downwash.
