Study Notes
Gyro Operation and Vacuum System
- Gyros operate using suction provided by a dry-type, engine-driven vacuum pump.
- The pump is gear-driven and connected through a spline-type coupling for efficient power transfer.
- A suction relief valve regulates system pressure, ensuring optimal performance between the pump inlet and instruments.
Vacuum Line and Instrumentation
- The vacuum line directs suction from gyro instruments to the relief valve, which is strategically placed at the firewall within the cabin.
- This configuration helps maintain the integrity of the vacuum system and protects the instruments.
Central Air Filter
- A disposable central air filter is installed in the system to prevent contaminants from entering gyros and maintain performance.
- The filter is designed for quick replacement, facilitated by straps that allow for easy removal and installation.
Suction Gauge Monitoring
- The suction gauge measures the net difference in suction pressure before and after airflow passes through a gyro.
- As the central air filter collects dirt and debris, the differential pressure decreases, leading to a lower suction gauge reading, indicating the need for filter maintenance.
