What are the different types of airplane tail fins?

Airplane tail fins, or empennages, come in several types, primarily including the conventional tail, T-tail, and V-tail designs. The conventional tail features a horizontal stabilizer and a vertical fin, while the T-tail has the horizontal stabilizer mounted at the top of the vertical fin, providing better performance at high angles of attack. The V-tail combines both stabilizing surfaces into a single "V" shape, which can reduce weight and drag. Each design has its own aerodynamic advantages and is chosen based on the specific requirements of the aircraft.
