If there is a leak in the #1 primary servos and no pilot action is taken, what is the final advisory?

• A. Tail rotor is stuck
• B. Yaw hold degraded
• C. Lots of warnings
• D. Electrical fault indicated

Answer: (C)

Hydraulic systems drive the main flight controls, so a leak in the #1 primary servo immediately reduces pressure in that circuit and trips the advisory logic for multiple faults. If the pilot does not take action to isolate or reduce hydraulic demand, the system cascades warnings across several subsystems. The cockpit ends up displaying a broad set of indications, culminating in a general “lots of warnings” advisory. This is why that option best captures the situation: a single specific fault message isn’t enough when the hydraulic degradation affects multiple controls and systems. The other possibilities would reflect a more isolated or different fault condition, not the broad warning state you get from an unmitigated hydraulic leak.
