Which statement triggers the amber PTU reservoir indicator?

Which statement triggers the amber PTU reservoir indicator?

• A. Reservoir level in Green or Yellow is low
• B. Reservoir level in Blue is low
• C. Pressure in Yellow is high
• D. Pressure in Green is high

Answer: (D)

The amber PTU reservoir indicator is tied to the status of the Green hydraulic circuit and the PTU’s reservoir charge. When the Green system pressure is high, it shows that the PTU reservoir is being charged and that PTU-related support is available if Green pressure were to drop. That’s why the statement about Green pressure being high triggers the amber indicator—it signals PTU involvement or readiness rather than a fault. The other options refer to reservoir levels in other colors or to pressure changes in Yellow, which aren’t what this particular amber indicator monitors.
