A new roughness evaluation procedure is needed, especially, when dealing with modern fighter jets. To this end, a comprehensive pilot attitude survey was conducted in Israel in order to gain reliable subjective runway roughness ratings. These ratings were to provide predicted roughness index values using objective measurements of a newly adopted geometric numeric, also capable of detecting critical rough segments along the entire runway. Additionally, some braking distance tests were included in the study and found to be important inputs for the development of the required criteria, along with various TAXI computer runs carried out on some pre-defined theoretical surfaces. All of the above led to the final criteria for the 'should be repaired' level, the 'must be repaired level' and the structural safety level for the fighters' landing gears.
