Publishing information occurences

LVNL publishes a quarterly summary of notable operational incidents. We also will be releasing the results of specific incident investigations that meet certain predetermined criteria and conditions.

Our intention in doing this is to provide interested parties with a greater insight into the safety situation at civil airports in the Netherlands by issuing factual descriptions of potentially serious incidents and explaining how safety in air traffic control (ATC) is managed. After a year we will review this change to our communications policy and, if desirable, modify it based upon our experiences during that initial period.

Publication criteria

LVNL publishes information about incidents which meet the following criteria. The incident must be related to LVNL’s executive task. In other words, it must fall within the domain of air traffic control. This definition excludes technical and operational matters affecting aircraft, airlines and airports. The incident must have been reported to the Dutch Safety Board (DSB). Some examples:

  • Losses of minimum separation between aircraft;
  • Take-offs or attempted take-offs from an out-of-use or occupied runway, or from one not authorised for take-off by air traffic control;
  • Landings or attempted landings on an out-of-use or occupied runway, or from one not authorised for landing by air traffic control;
  • Runway incursions with actual or potential risk of collision.

 

How the system works in practice

Whenever an incident is reported to the DSB, a notification is posted on the LVNL website as quickly as possible (within five working days). This notification is linked to a dossier, which is updated as and when the investigation produces relevant findings. Effectively, the publication of incident information is divided into four steps. 

  1. Initial notification of an ATC-related incident at www.lvnl.nl, within five working days. To qualify for such notification, the incident must be reportable to the DSB and be potentially serious in nature.
  2. Publication of the basic facts about the incident. This occurs at a later stage, but exactly when depends upon the progress of the investigation.
  3. Once the investigation has been completed, publication of a factual description of the incident and relevant findings.
  4. Optionally, LVNL may add more information later if the investigation so dictates.

 

Publication restrictions

By law, LVNL is not permitted to issue any communications concerning serious incidents resulting in death, injury or material damage. The reason for this restriction is that any such communication might compromise independent investigations by other bodies.
