The present technology relates to a measurement apparatus 200 for determining a bending moment 230 acting on a rotor shaft 210 of a rotary-wing aircraft 100 as well as to a method of operating such a measurement apparatus 200. The measurement apparatus 200 includes a processing system 250 and a sensor arrangement 224 that is mounted to a rotor blade 112 which is attached to the rotor shaft 210. The sensor arrangement 224 includes a sensor 224a that generates a signal 620 in response to a force or moment 320 acting on the rotor blade 112. A cable 222 transmits the signal 620 from the sensor 224a to the processing system 250, and the processing system 250 determines the bending moment 230, 670, 680 acting on the rotor shaft 210 based on the signal 620 from the sensor 224a.
