After a lull in traffic due to the COVID-19 pandemic, Schiphol and the surrounding airspace is again reaching peak capacity during its operations, leading to Network Manager (NM) regulations. When a departing flight is regulated its sequencing process by the Pre-Departure Sequencer is different from non-regulated flights, possibly leading to delays stacking and an even later Calculated Take-Off Time being issued by NM. These feedback effects are currently not well understood and some parameters in the process are not well explored in regards to finding an optimum, either local or global. In this research the A-CDM EHAM process and related systems will be modeled in order to reach new insights into the effects of varying communication time horizons and the effects of the varying data streams on the total departure capacity of Schiphol.
