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.
