Definition: Coupled yaw–roll oscillation; pronounced with swept wings.
Physics insight: Shaped by lateral stability, wing sweep, and dihedral effects.
Example: Without yaw damper, the oscillation can grow; comfort and handling degrade.
Yaw-damper raises ζ_dr (damping).
Rules of thumb: Operate yaw damper per flight phase procedures.
Common pitfalls: Exceeding speed limits during failures.
