Abstract	The fidelity required for piloted simulation, especially the need for motion cueing, remains a hotly debated question. The answers are dependent on the objectives of the simulation and the nature of the task. Is the purpose of the simulation to evaluate flight control designs, handling qualities, or vehicle performance or is it to train pilots? Of course, the motion fidelity requirements may differ greatly, for example, between commercial pilot training and fighter and rotorcraft pilot training. While it is beyond the scope of this paper to provide such answers, results from a recent program conducted by Systems Technology, Inc. are presented that compare data collected from an in-flight simulator with a fixed-base simulator. The program featured five test pilots performing five handling qualities demonstration maneuvers with several aircraft configurations over a single test sortie. The sorties were first performed in-flight and were then repeated in the simulator. In this paper, the task performance, pilot ratings, and pilot-vehicle system results focus on the continuous pitch and roll tracking tasks wherein the impact of the “seat-of-the-pants” motion cues present in the pitch axis tracking tempered the pilot inceptor inputs in flight when compared to the fixed-base simulator. Similar results were not observed for the roll axis tracking task.
