Within the framework of the national and international safety plans, aiming at maintaining acceptable aviation
safety levels, researches are conducted to mitigate runway overrun during landing – inability for the aircraft to stop
before the end of the runway – which continues to be the top three risk in commercial air transport (IATA, 2015).
This section illustrates how airport ground-traffic surveillance system data served as a basis to identify pertinent
landings in order to encourage opportunities for dialogue on such a risk.
The data set that was used consists of more than 250,000 landings on a major international French airport over
a period of 13 consecutive months covering a complete aeronautical and meteorological year. Traffic data from
ground surveillance system and weather data had been used.
Choice has been made to open a meaningful discussion by easily providing relevant information about
automatically detected landings of interest with regard to runway overrun risk among the several thousand landings
available on the airport. These selected landings are identified through a number of characteristic criteria for
determining factors of runway overruns. As a first approach, two criteria are used to identify a pertinent landing:
a high runway exit speed and a high speed at 600 m before the end of runway. Other parameters with a lower level
of quality are additionally provided for information (see Table 2).
