Keywords: calibration parametric study, loads calibration optimization, loads calibration test, loads test design, strain-gage calibration

Documents a parametric study of various aircraft strain-gage load calibration test features that affect the quality of the resultant derived load equations. The effects of the following are compared: single-point and distributed loading, variation in applied test load magnitude, number of applied load cases, and wing-box-only compared with control-surface loading.
