Medical helipads have been assigned the identification codes EH0001 to EH0031 by the Dutch authorities, but these are not official ICAO indicators and thus these helipads are not included in this list. The Maasvlakte and IJmuiden helipads are restricted to maritime piloting services and are not connected to the AFTN network. Air Operations Control Station Nieuw-Milligen is a military air traffic control centre and has a single helipad for military use.
