Runway roughness as it affects aircraft response and human comfort was analyzed, and two human failure criteria approaches were investigated. Although generally unsatisfactory, human-absorbed power as a criterion for roughness was found to be informative for locating severe rough areas. A third-octave band approach to establish human criteria acceleration levels was more accurate. However, this approach revealed that aircraft response data was usually far below the criteria levels for human comfort, even on runways known to be rough. Because of the lack of suitable criteria, statistical analysis of both the roughness and the aircraft response data was performed. In this manner, profile roughness was placed on a relative basis. Statistical techniques were then described whereby both overall and detailed profile roughness properties could be classified. The establishment of detailed roughness statistics was considered incomplete, and additional work was recommended in this respect. /FAA/
