Best Practice – Data Analysis

  • Apply a risk matrix to infringement data. The application of a risk matrix is essential to enable resources to be targeted on initiatives that will produce the most benefit.
  • Use a risk matrix to enable risk reduction initiatives to be measured.
  • Look for hotspots to tackle first and with most effort.

Cost – Some staff costs to provide data analysis


EUROCONTROL analysis shows that whilst the overall number of serious incidents is decreasing, still more than 40% of infringements fall into the significant to serious category. Analysis such as this has resulted in the EUROCONTROL initiative to reduce the risk of infringements; including workshops, risk reduction recommendations and a host of other activities including this guide. In local settings countries have used risk severity data to justify significant expenditure on safety improvement. In the UK it was identified that the most serious risks were associated with a lack of detection of infringing aircraft for two reasons: controller workload and aircraft without transponders. Initiatives to tackle these two areas have resulted in a large reduction in risk even though the number of reported infringements has continued to rise. Identification of hotspots has also led work to be focused on specific areas of the London TMA and to the introduction of a new Lower Airspace Radar Service (LARS) in that area.
