How are propeller blade stations measured?

Explanation:
Blade stations are defined by a fixed radial position measured from the hub centerline—the imaginary axis through the center of the hub where the blade root attaches. Each station is a specific distance along the blade from that hub axis toward the tip, giving a consistent reference point for locating features and taking measurements. This way, regardless of blade length or orientation, you can identify exact locations on every blade for inspection of thickness, camber, and other dimensional checks. Measuring from the hub centerline keeps the reference constant, whereas measuring from the tip or other ends would vary with blade length and mounting.
