The Horizontal Tail Volume Ratio in flight mechanics refers to the ratio of the horizontal tail volume to the total wing volume. A proper (VH) is essential for ensuring that the horizontal tail surfaces provide sufficient stability to maintain the desired pitch attitude and control the aircraft during various phases of flight, including takeoff, cruise, and landing. The formula to calculate Horizontal tail volume ratio as follows:
Where:
- lt is the Horizontal tail moment arm,
- St is the Horizontal tail area in m2.
- S is the wing area in m2.
- Cma is the Mean aerodynamic chord in m
