    Study Notes

    Vacuum System Components

    • Two engine-driven dry vacuum pumps
    • Two vacuum regulator valves containing filters
    • A check valve
    • Tubing on each engine
    • A vacuum gauge
    • An air filter

    Vacuum System Operation

    • Monitors vacuum levels using a vacuum gauge
    • Check valve closes automatically if vacuum is lost from either pump or other system malfunctions
    • Vacuum is then supplied by a single pump
    • One of two red malfunction buttons will appear on the vacuum gauge if vacuum is not available from either pump

    Vacuum System Function

    • Increased gyro lifespan due to an air filter
