The operability valve works in conjunction with which component?

• A. Variable Guide Vanes
• B. N2 Compressor
• C. N1 Fan
• D. Accessory Gear Box

Answer: (A)

The operability valve is part of the engine’s flow-control system and works to adjust how air enters the compressor. It does this by directing hydraulic or other control signals to the Variable Guide Vanes, which are the devices that actually set the angle of the airflow into the compressor. By coordinating with the VGVs, the operability valve helps optimize airflow across different power settings, maintain compressor stability, and support bleed/air system demands. The N1 and N2 spools aren’t directly operated by this valve, and the Accessory Gear Box is simply where engine accessories live, not where airflow control is managed. So, the operability valve works in conjunction with the Variable Guide Vanes.
