AAS is at the final stage of having Airport- collaborative decision making (A-CDM) completely implemented. The last step is to connect the network manager and then AAS will be a CDM airport. The network manager is currently not yet connected and, therefore, not taken into account in this study since there is not any data available yet. Local A-CDM is currently implemented at AAS which includes the four other main stakeholders (Airport operator, Aircraft operator, ATC and ground handlers). Local A-CDM should improve the stakeholders’ operational efficiency by improving the predictability and decision making.  It is likely that A-CDM has been beneficial for the operation of each involved stakeholder at AAS. However, for all stakeholders it is still uncertain how much the operational efficiency has improved thanks to the implementation of local A-CDM. The aim of this study is researching how local A-CDM has exactly improved the operation’s efficiency for each involved A-CDM stakeholder at Mainport Schiphol until now, and what the exact benefits are.

ATC controllers are respected for their high-performance jobs, training is consistent and on high quality level, still the individual controller has the opportunity to guide air traffic in the most efficient way for that moment. An analysis of ATC decision making (taxiway, gates, runway usage, approach and take-off routing), finding deviations and variations in the operation, should determine the current way of working and should form the basis to work towards APOC. In APOC, a key difference between the current situation is the way of information sharing and availability, this difference with the current situation should be analyzed, providing the insight how to transition towards the use of APOC. The results must provide how the current decision-making process impacts capacity and to what extent can these deviations and variations be reduced when APOC is used. Furthermore, what are benefits and what are the requirements to transition to this future situation. In addition, also maintaining sufficient flexibility in the operations after the decisions have been made.

Schiphol has the most runways in Europe with respect to major hub airports, this does not automatically translate to the highest ATMs. During the day runway use is changed, primarily because of the noise restrictions surrounding Schiphol. An analysis of the impact on the capacity on the ground and in air, is needed to determine, how this already complex change of runways also increases the complexity in other parts of the system. Included in the analysis the effect on TATs can be determined possibly through A-CDM data, also information from the ORS (Omgevingsraad Schiphol) must be considered as input. The results must provide an effect analysis on specific parts of the system and the reasoning, the related stakeholders need to be covered also the cost and benefits in operational sense need to be addressed.

Air traffic controllers find the most efficient way to align aircraft towards the runway, maintaining separation requirements, trying to prevent delays, choosing the most fuel-efficient routes for airlines from and to the airport. Although in some cases regulations in the airspace are deemed necessary to cope with an increase in demand, on top of that pilots (airlines) tend to defeat the system by asking for directs (deviations), instead of following the rest. In addition, relaxing some airspace constraints did not have the effect of a higher utilisation of the airspace. The analysis should provide insight in the effectiveness of limitation/regulations used in the airspace. Possible input can be an aircraft priority study (KLM), that provides the airline with information which aircraft to speed up or slow down. The results of the research must provide air traffic controller with the impact of certain regulations and also airspace users with the insight on how their decisions impact the whole system. Included should be at least a list of the most used regulations with their impact/effectiveness and deviations by users including their impact as well. The customer wants to get insight in the current effectiveness of Network Manager regulations, and in particular the effect of airline/pilot behaviour on the effectiveness of regulations.
