List of air lubrication system power values in kilowatt (kW), summed over all compressors.

Propeller pitch angle in degrees (°). A pitch angle of 0° indicates the neutral position. Positive values correspond to forward thrust (blades angled to push water aft), negative values to reverse thrust (blades angled to push water forward).

Propeller pitch as a percentage of maximum ahead pitch. 0% corresponds to zero blade angle (no thrust), 100% corresponds to maximum ahead blade angle (maximum thrust). Negative values indicate astern pitch if supported by the vessel. Values are accepted from -200% to +200% to allow sensor or vessel-specific scaling beyond the nominal range.
