29. Last minute runway combination changes
Runway combination changes that take place at the last minute may cause a disruption to the expected flight handling process, both for pilots and air traffic controllers. Air Traffic Control the Netherlands (LVNL) and Schiphol have developed measures to further reduce the number of last-minute runway changes, and the associated risks, in order to prevent air and ground safety incidents. For instance, we maintain landing runways when an aircraft is in the Terminal Maneuvring Area (TMA) Schiphol; in addition, we use two departure runways when needed for a more stable traffic flow. We also use improved planning systems. These measures enable the percentage of last-minute runway combination changes to structurally decrease. We have now completed the investigation into the effect on safety of these and additional measures.
