How many cautions are associated with the stabilator?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

Cautions in flight control systems warn you about conditions that can damage equipment or affect safe operation. The stabilator on the UH-60S is driven by two independent hydraulic/servo pathways, so there are two separate caution notes to cover each possible failure path. One caution alerts you to issues that could cause loss of stabilator function or uncommanded movement if a hydraulic or servo problem occurs, while the other addresses problems like binding, leakage, or contamination that could restrict stabilator travel or degrade control. Because two distinct failure modes can affect stabilator performance, there are two cautions rather than just one.
