Dihedral effect, Roll due to side slip
Directional Stability, Yaw due to side slip
Heading
Side slip
Yaw due to roll rate
A component of ADVERSE YAW (not the same as yaw due to roll control)
p
Roll Rate
r
Yaw Rate
Roll due to yaw rate
ROLL DAMPING, Roll moment due to roll rate
Rolling moment caused by ailerons
Steady state roll rate:
Steady state roll rate, equals:
Roll mode time constant:
Aileron deflection
Yaw damping (yaw moment due to yaw rate)
Spiral root
Given by the sign of: (Dihedral*Yaw Damping - Directional Stability * <roll>)</roll>
