“Landing overruns are normally not caused by one single factor and some factors could be related”
In addition to the report on long landings (#12), the importance of combined factors is also indicated in a recent
analysis of Boeing aircraft overruns. The chart on page 10 has three groupings; each respectively showing long landings associated with higher speeds, fast touchdowns with tailwinds, and use of deceleration devices and timing. A common theme in all data is the reduced braking action, but an important aspect relating what conditions were reported or perceived, vs what the actual braking action was, is not available.
