This paper focuses on the prediction of disturbance effects of the vertical acceleration of an aircraft in atmospheric turbulence. To this end, 5-hole probes with high-dynamic differential pressure sensors are installed in front of a fixed-wing unmanned aircraft system (UAS) to measure the local airspeed and angle of attack of the airflow. Test flights are performed in moderate and severe turbulence to assess the anticipating character and the accuracy of the predicted acceleration. Thereby, depending on the flown airspeed, anticipation times up to 0.1s are observed. The prediction accuracy is assessed to be 93.65% for moderate turbulence and 87.78% for severe turbulence, where vertical acceleration disturbances higher than 30m/s2 are measured.
