ANALYSIS OF AIRPORT RUNWAY ROUGHNESS CRITERIA

The recommended procedure is that a statistical analysis of profile data be used to establish a roughness criterion. This implies that aircraft-vibration-response data need not be considered in establishing roughness criteria, even though these data can provide supporting evidence of the degree of roughness. Hence, the aircraft itself is not a factor in the recommended approach. The statistical analysis of profile-elevation data is possible if the data are filtered to remove the elevation trends that are formed by long wavelengths. A profile can then be rated according to its overall and its detailed roughness properties. The standard deviation of displacement (sigma) is recommended as an overall index, and the standard deviations of the slopes and the slope changes might be considered as detailed indexes (extremal analysis). The detailed roughness properties are necessary because a profile may be generally smooth, yet have a few severe bumps. The statistical approach discussed here addresses only the determination of the standard deviation of displacement as an overall index; additional work is recommended. Finally, when all known indexes are extracted for the profile data, each should be correlated with subjective pilot ratings, and those showing the strongest agreement should be emphasized. /Author/
