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 European Commission delegated the delivery of the airspace architecture study (AAS) to the SESAR Joint Undertaking (SJU).
In order to improve the ATM operation in the future, Gatwick Airport Ltd. needed to develop, and deliver on, an ATM performance improvement plan. This would present a roadmap of operational improvements that the business should focus on in order to deliver benefits going forward.
European legislation required Member States to redesign their airspace to enable airports to benefit from RNP1. In the UK, the Future Airspace Strategy (FAS) promotes adoption of PBN as the enabler of airspace modernisation for all phases of flight. Moreover, NATS has initiated a process of navigation aid (NAVAID) rationalisation, which includes the removal of VHF Omni-directional Range (VOR) transmitters currently used by aircraft flying RNAV procedures. The combination of these factors has led to many UK airports needing to update their arrival and departure procedures.
