OverRun:
Fascinating stuff - that's the first time I have seen any proper analysis of rough runway effects.
A couple of stories:
When the RAF started operating Harriers from field sites, roughness became an issue. A practical test was evolved - if a LandRover could be driven down the strip at 40 mph without excessive discomfort to the driver (hardly an objective test) then it was OK for flying. It seemed to work, though.
The other: a Mediterranean airfield that had better remain anonymous in case the lawyers read this, 1990s. The airline I flew for at the time took B757 & 767 there, and the only runway had a severe bump from subsidence, so bad that a colleague's B767 on take-off was tossed into the air below V1 one day. We got Boeing to do an analysis of the QAR data, and they were seriously concerned about structural loads. After much argument, the runway was improved.
