Solution for Castricum-Limmen night flights takes longer than expected
Since 28 May 2015, there have been more night flights in the airspace over Castricum and Limmen. This is due to the discontinuation of one of the two regular night-time flight paths for safety reasons. As of this date, all aircraft landing on the Polderbaan at night have a final approach that takes them over the municipality of Castricum. During the Regional Forum of Schiphol Community Council on 26 February 2016, Luchtverkeersleiding Nederland (Air Traffic Control the Netherlands, LVNL) announced that realising the envisioned definite solution for this problem was taking longer than expected. LVNL intended to have implemented a definite solution by mid-2016. Due to the complexity of the required technical adaptations, LVNL currently expects a two-year delay in this programme. In April 2016, LVNL will provide Schiphol Community Council with further details on the performed analysis and the planning, specifics and effects of the intended solution.
Since 28 May 2015, Luchtverkeersleiding Nederland (LVNL) no longer uses the shortened night-time approach (ARTIP2C) due to a safety issue with this route. This route runs from Hoorn to the Polderbaan. This means that night-time air traffic arriving from the east with a final approach on the Polderbaan now takes ARTIP3B: the route that passes over the sea via Castricum and Limmen. As a result, there is more night-time air traffic in the airspace over Castricum and Limmen and neighbouring municipalities like Bergen.
LVNL’s planning system did not prove precise enough to perfectly coordinate the two night-time flight paths for air traffic coming from the west and the east with a final approach on the Polderbaan. As a result, the planning could not guarantee sufficient distance between the aircraft at all times. LVNL was forced to stop using this approach to comply with increasingly stringent security requirements.
