### PRESSURE INDICATION <a href="#pressure-indication" id="pressure-indication"></a>

* Digital Pressure
  * Amber indicates cautionary operating range.
* Pressure Scale/Pointer
  * If scale or pointer is amber that indicates the cautionary operating range.

### QUANTITY INDICATION <a href="#quantity-indication" id="quantity-indication"></a>

* Displays the percentage of fluid remaining for each hydraulic system.
  * Green – normal quantity, Cyan – reservoir requires refilling.

### TEMPERATURE INDICATION <a href="#temperature-indication" id="temperature-indication"></a>

* Indicates the hydraulic fluid temperature measured in the reservoir.
* Green – normal operating range, Amber – cautionary operating range, Red – operating limit exceeded.

### ENGINE PUMP SHUTOFF VALVE STATUS <a href="#engine-pump-shutoff-valve-status" id="engine-pump-shutoff-valve-status"></a>

* Depicted as a circle with an internal line representing the valve position.
* IN TRANSIT: white circle and a white line diagonal to the flow line.

### ELECTRIC HYDRAULIC PUMP STATUS <a href="#electric-hydraulic-pump-status" id="electric-hydraulic-pump-status"></a>

* Circle with an internal windmill.
* The icons that represent electrical pumps are smaller than the engine-driven pump and PTU icons.

### ENGINE DRIVEN HYDRAULIC PUMP STATUS <a href="#engine-driven-hydraulic-pump-status" id="engine-driven-hydraulic-pump-status"></a>

* Depicted as a circle with an internal windmill.

### POWER TRANSFER UNIT STATUS <a href="#power-transfer-unit-status" id="power-transfer-unit-status"></a>

* Depicted as a circle with an internal windmill

### HYDRAULIC FLOW LINE <a href="#hydraulic-flow-line" id="hydraulic-flow-line"></a>

* Green – flow line is pressurized, White – not pressurized, White/Amber dashed – pressure is undetermined.

### HYDRAULIC SYSTEM DISTRIBUTION BOX <a href="#hydraulic-system-distribution-box" id="hydraulic-system-distribution-box"></a>

* Each distribution box indicates the airplane’s systems supplied by the respective hydraulic system.
* Green – associated hydraulic system is pressurized, White – not pressurized, White/Amber dashed – pressure is undetermined.
