This study reviews several methods for describing the intensity of a vibration of ride-quality environment and its effect and comfort, proficiency and fatigue. These methods are applied to vibration environments encountered during B-1 low-altitude, high-speed flight tests. The resulting vibration environmentride qualtiy descriptions are correlated with qualitative assessments of turbulence levels and impact on performance and discomfort obtained from the crew. This correlation provides an evaluation of the sensitivity of the methods in predicting the effects of variation in the vibration in the vibratoin environment. To evaluate the precision of the methods in predicting ride quality ratings for a high-speed low-altitude environment, the qualitative assessments of the crew are compared to ratings, boundaries or limits established by the different methods.
