The operability valve is designed to work in conjunction with the Variable Guide vanes.

• A. True
• B. False
• C. Not specified
• D. Cannot determine

Answer: (A)

The operability valve is part of the engine’s variable geometry control system. It provides and regulates the pressure that positions the Variable Guide Vanes, enabling the vanes to adjust airflow into the compressor as the engine moves through different operating conditions. This coordination ensures proper airflow, compressor stability, and safe, efficient operation across the flight envelope. Because the valve’s function is to support and control the VGVs, the statement that they are designed to work together is true.
