The technical feasibility of providing Air Traffic to a location other than the aerodrome had been proven as technically feasible in the late 2000s.  As part of the SESAR Development programme a consortium of European partners were tasked with creating a brand new operational concept and maturing it to a point where it could be implemented. 

Our client – a large airport with operating under High Intensity Runway Operations on a single runway – wished to investigate the feasibility of dual runway operations prior to making any formal planning or implementation decisions.  Critical to the feasibility of dual runway operations was the safety case for dual runway operations. 

The European Parliament requested the European Commission to conduct a study on the Single European Sky (SES) airspace architecture and more specifically, how changes to the existing airspace architecture could support implementation of the Single European Sky.  The EC delegated the delivery of this study to the SESAR Joint Undertaking (SJU).
