Study Notes

Turbulence Damping Function

Dampens structural modes caused by atmospheric turbulence.
Employs Nz accelerometer and two Ny accelerometers.
Computes a turbulence damping command using PRIMs.
Added to elevator and yaw damper commands.
Automatically deactivated upon failure detection.
Manually inhibitied by switching off TURB DAMP pushbutton if comfort is degraded.
Only active under specific conditions:
- Aircraft in flight.
- Aircraft speed exceeding 200 kt.
- Autopilot engaged or normal law active.
- Aircraft within normal flight envelope.
