If air-to-ground imaging sensors are mounted to aircraft by different gimbal order systems, the displayed scene will rotate differently, even though the flight paths are identical. Eighteen experienced pilots were tested to investigate the effects of three gimbal orders (roll-pitch, yaw-pitch, and pitch-yaw) on target detection, recognition, and identification performance, and also on operator workload. The pitch-yaw gimbal order was associated with the greatest range-to-target scores and the lightest workloads.
