What should be the color of the strip on the Waste Temperature Sensor for it to be satisfactory?

The color of the strip on the Waste Temperature Sensor indicating a satisfactory status is white or silver. This color coding is used to provide clear visual identification of acceptable operational conditions. When the strip is white or silver, it indicates that the temperature is within the normal range and that the waste system is functioning properly without any risk of overheating or malfunction.

Using white or silver for satisfactory readings helps ensure consistency and clarity in monitoring equipment status, which is important in a high-stakes environment like aviation. Proper identification of sensor readings allows flight attendants and maintenance personnel to quickly assess the condition of the waste system, ensuring safety and efficiency on board. This color is distinct from other options, which represent different operational states or alerts.
