Abstract:

A simulator facility was built to study the effects of vibration on pilot tracking performance using a rigid control stick. Tests were conducted at frequencies from 5 to 50 hertz and accelerations up to 1.5 gs. Two vibration environments were studied control stick vibration and whole body vibration. Twenty-two different frequencyg-level combinations were tested. The order of the runs was varied for each subject in an attempt to cancel out consistent learning effects. In general, performance scores for whole body vibration were lower than those for control stick only vibration although g-levels were less. All subjects experienced greater discomfort on the whole body vibration tests. All subjects showed a noticeable drop in performance on some runs in the 20-25 Hz frequency range.
