Variables Used
Yawing Moment with Rudder Deflection Angle - Yawing moment with rudder deflection angle is the rate of change of deflection.
Vertical Tail Efficiency Factor - Vertical Tail Efficiency Factor is defined as the ratio of the yawing moment produced by the vertical tail to the product of its surface area and the square of the wingspan.
Velocity at Tail Plane - (Measured in Meter per Second) - The velocity at tail plane of an aircraft refers to the airspeed experienced by the tail surfaces.
Change in Coefficient of Lift Refers to Tail Plane - The Change in Coefficient of Lift Refers to Tail Plane refers to the variation in lift generated by the tailplane of an aircraft.
Change in Rudder Deflection Angle - The change in rudder deflection angle refers to the variation in the angle by which the rudder is deflected from its initial position.
