Horizontal Tail Angle of Attack Calculator

The horizontal tail angle of attack in flight mechanics refers to the angle between the chord line of the horizontal tail surfaces and the oncoming airflow. This angle is critical for the aerodynamic performance and stability of the aircraft. The horizontal tail angle of attack is typically set to contribute to the overall stability and control of the aircraft. It influences the lift generated by the tail surfaces, affecting the balance of forces and moments that determine the aircraft’s pitch motion. The formula to calculate horizontal tail angle of attack as follows:

Where:

  • is the angle of attack of the wing in radian,
  • is the angle of incidence of the wing in radian,
  • is the downwash angle in radian,
  • is the angle of incidence of the tail in radian.
