The purpose of this recommended practice is to establish a standard format for the presentation of helicopter mission data, which will provide data required to establish airframe and/or engine component life.

Recommends that Mission data in table form (Figure 1), be supplemented in graphical time histories (Figures 2 through 4) incorrectly marked as mission histograms. Histograms are not provided. Power Y-axis in percent of maximum rated power shows IDLE and shutdown as negative values.
Task: update and relabel the figures, add the corresponding mission histograms (frequency distribution of power values),
