HLSR—Yaw Axis Response Criteria
Bandwidth criterion: The BW criterion of yaw axis response (YAR) is similar to the PAR BW criterion; however, the minimum limits imposed are higher than those for the pitch axis.
Dynamic stability criterion: Here, more relaxed limits are placed on the damping ratio than pitch – and roll-axis oscillations. For Level 1, the minimum value of 0.19 is specified for yaw damping ratio for all oscillations with a frequency of more than 0.5 rad/s.
Attitude quickness criterion: The parameters are the heading quickness and the minimum heading change Dcmin required.
Large amplitude criterion: The large amplitude heading changes is for yaw control power in terms of the maximum achievable yaw rate: the limit for moderate agility MTE is ±22°/s for Level 1 HQ.
