Flight loads measurement is necessary for new type aircraft developing. Control surface hinge moment measurement is an important part of Flight loads measurement for an aircraft. An flight loads measurement technique for short rods was proposed in this paper，the technique in this paper was applied to measure flight load at certain aircraft; The response coefficient of strain-gage bridge differences up 45% when pull & press calibration test for the short rods, so, the opinions of flight loads measurement for short rods need to calibration pull & press two loads case was proposed in this paper.
