Runway incursion prevention, an ongoing challenge
Runway incursions are rare events and existing implemented preventive and mitigation measures participate in keeping their numbers and severity as low as they can be. However, they constitute a major and acknowledged safety threat amongst the aviation community. In this respect DSNA has set the reduction of runway incursions as one of its utmost safety improvement objective.
Classification & risk assessment method…
ICAO defines runway incursions as being « any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle or person on the protected area of a surface designated for the landing and take-off of aircraft.”
In order to help DSNA’s safety cells build an accurate risk picture of runway incursions, all occurrences must primarily be thoroughly collected. In this respect, all operational actors (i.e. DSNA’s ATCOs, Aircraft Operators crews and airside drivers) are encouraged to systematically report runway incursions when they occur.
Thereafter, events are classified according to the European severity classification scheme “RAT” (Risk Assessment Tool). Serious and major ATC contributions are particularly looked into even if whatever the severity of the occurrence, all runway incursions are adequately investigated.
…for adjusted and relevant prevention measures
To mitigate the severity of runway incursion events and cut down their numbers, corrective and/or preventive actions are implemented. They address all identified critical areas of concerns : aerodrome lighting, markings & equipment improvements, ongoing ATC training, specific situational awareness information campaigns, simplification of procedures, phraseology, Human Factors, etc…
The establishment of Local Runway Safety Teams has been identified as an additional means to advise all relevant runway operations actors on potential runway incursion issues and recommend mitigation strategies. Airport Operators are responsible for their coordination. LRST meet on a regular basis and concern the following 11 DSNA’s airports : Paris Charles-de-Gaulle, Paris-Orly, Nice-Côte d’Azur, Bâle-Mulhouse, Bordeaux-Mérignac, Martinique-Aimé Césaire, Lyon-Saint Exupéry, Marseille-Provence, Nantes-Atlantique, Strasbourg-Entzheim, Toulouse-Blagnac.
