The coefficient of yawing moment is a dimensionless quantity that measures the tendency of an aircraft to rotate about its vertical axis (yaw axis) due to a change in sideslip angle or yaw rate. It is usually denoted by Cn or Cnp
- (rho): The air density.
- : The velocity of the aircraft relative to the air.
- : The wing area.
- : The wingspan of the aircraft.
- N is the yawing moment
- Cn is the yawing moment coefficient
