This study examines the transfer of training for pilots from the simulator to the aircraft for the task of receiver refueling. Receiver refueling requires the receiver pilot to position the aircraft behind the tanker aircraft and maintain the position while taking on fuel. This task is trained in the KC-10 flight simulator (six degree-freedom of motion system and day/dusk/night computer generated image visual system) during Pilot Initial Qualification and Refresher training. The investigation used student performance scores from both the simulator and aircraft for like conditions. Pilots completed critiques containing questions regarding the fidelity and usability of the simulator visual and motion system as compared to the actual aircraft and real-world refueling environment. The results showed a positive transfer of training with implications for the training of air refueling and the configuration of training devices.
