Operational Concept for a Complete A-SMGCS

The basic idea of this paper is to identify a comprehensive A-SMGCS (Advanced Surface Movement Guidance and Control System) concept that allows incorporating the full scope of surveillance, guidance, routing and control services as well as new onboard related A-SMGCS services including their air-ground interoperability. This concept approach supports the stepwise implementation of a complete 
A-SMGCS at a specific airport with its specific needs. These results are an output of the European project EMMA (European Airport Movement Management by A-SMGCS), an Integrated Project launched by the European Commission in its sixth framework programme. The paper identifies all A-SMGCS services, their evolutionary implementation steps, and gives recommendation to the composition of implementation packages (IP) to meet the airports’ specific needs.
