🔍 Key Concepts

• Trace the flow of control signal from the wheelhouse/bridge unit down to the pitch-changing mechanism in the hub on illustration GS-0170. • Distinguish between components that drive the hydraulic oil to move the blades and components that only give position feedback/indication. • Note which items in the diagram are air or clutch related versus those that are part of the electro‑hydraulic control loop for CPP pitch.

💭 Think About

• From the symptoms “slow, erratic, or no pitch response,” ask: which part, if it fails, would directly affect how quickly and correctly hydraulic oil is ported to the main servo piston? • Look at the box(es) labeled near the main servo and pitch pump: which device converts an electrical command (desired pitch) into hydraulic movement? • Consider what a feedback device does: if it failed, would the blades stop moving properly, or would you mainly lose accurate indication / fine control while the basic response still occurs?

✅ Before You Answer

• On GS‑0170, positively identify the component that is both electrical AND hydraulic (controls oil flow based on an electrical input). • Confirm which component’s failure would cause the entire system to respond sluggishly or not at all, not just give a wrong reading on a gauge or indicator. • Eliminate any choices that are clearly part of starting air, clutches, or other systems that do not directly port oil to the pitch servo in a CPP system.
