The Horizontal Tail Area in flight mechanics refers to the total planform area of the horizontal tail surfaces of an aircraft. It includes the area of the horizontal stabilizer and elevator. The horizontal tail plays a crucial role in maintaining the aircraft’s longitudinal stability and control. The size and design of the horizontal tail area are critical factors in ensuring proper balance and control during different flight conditions, such as takeoff, cruise, and landing. The formula to calculate Horizontal Tail Area as follows:
Where:
- VH is the Horizontal Tail Volume Ratio,
- S is the Wing Area in m2,
- Cma is the Mean aerodynamic chord in m,
