Study Notes
Yaw Damping and Turn Coordination
- Three hydraulic servojacks are controlled by a green hydraulic servo-actuator.
- A yellow servo-actuator acts as a backup, maintaining synchronization and taking over if the green one fails.
- Rudder pedals have no feedback from yaw damping and turn coordination systems.
- Backup Yaw Damper Unit (BYDU) is activated if there's a complete loss of electrical power or flight control computers, handling only yaw damping.
- BYDU uses an electro-mechanical actuator, working alongside the two standard yaw dampers.
- The BYDU includes a gyrometer and associated electronics.
- Two dedicated generators power the BYDU: one powered by the blue hydraulic system, the other by the yellow system.
