Downloaded from https://www.everyspec.com ADS-79D-HDBK digital source collector to monitor control input rates, flight control actuator loads, blade flapping, swashplate tilt, aircraft longitudinal/lateral CG accelerations, parking brake indication, trim ball indication, ground speed, ground track, and miscellaneous strain measurements. B.5.2.2 Flight state sampling rate. The CBM designer should select the appropriate sampling rate for acquiring flight state parameters. The selected rate should strike a balance between under- sampling with the potential of missing a desired effect and over-sampling which might produce more 54 TABLE B-VII:
