Which of the following describes a type of calibration sticker?

The correct answer refers to the white sticker with orange lettering that indicates a "no calibration required" status. Calibration stickers are important in aviation maintenance and operations, as they help personnel quickly identify the calibration status of equipment and tools.

Specifically, the white sticker with orange lettering is used to denote items that do not require calibration. This means that these items have been evaluated and found to be either inherently accurate or are not subject to precision requirements that would necessitate regular calibration. Such clarity ensures that the equipment can be used without unnecessary delays or miscommunication regarding its readiness for precise tasks.

In contrast, the other options describe different scenarios related to calibration. For example, the red sticker commonly indicates that no calibration is required, but it lacks the specificity of detailing whether the item has previously undergone calibration checks. The green sticker often signifies calibrated items, ensuring they are maintained within required specifications. The yellow sticker typically relates to default calibration, which may not apply to items that do not need calibration at all. Each of these sticker types serves a specific function, and understanding their meanings is crucial for effective equipment management in aviation settings.
