A piloted simulation study was conducted to examine the effect of motion cues using a high-fidelity simulation of a commercial airplane during the performance of complex curved approach and landing tasks in the signal environment of the microwave landing system MLS. The data from these tests indicate that in a high-complexity MLS approach task with moderate turbulence and wind, the pilot uses motion cues to improve path tracking performance. No significant differences in tracking accuracy were noted for the low- and medium- complexity tasks, regardless of the presence of motion cues. Higher control- input rates were measured for all the tasks when motion was used. Pilot eye scan, as measured by instrument dwell time, was faster when motion cues were used regardless of the complexity of the approach tasks. A pilot subjective rating, based on time load, mental effort load, and psychological stress load, yielded larger work load ratings with motion than with no motion. Pilot comments indicated that they preferred motion and that motion cues helped them accomplish their task, especially in turbulence and during the landing phase of the approach. With motion cues, pilots appeared to work harder in all levels of task complexity and to improve tracking performance in the most complex approach task.
