The Single European Sky ATM Research (SESAR) initiative aims to design and validate a future operational concept which enables all categories of airspace users to conduct their operations with minimum restrictions and maximum flexibility while meeting or exceeding a number of key performance targets.The SESAR initiative must also take into account the global nature of air transport and therefore be compatible, notably from a technology perspective, with similar initiatives such as NEXTGEN in the United States.The SESAR operational concept [8] is a trajectory based system with the trajectory being sourced by the airspace user and executed in so far as possible according to the user requirements. At each stage of the planning and execution phases of a flight, the trajectory information will be shared between relevant actors via a System Wide Information Management (SWIM) network. The Network Operational Plan (NOP) will ensure a flexible and continuous balancing of capacity and demand through dynamic airspace management in order to adapt available resources to the required demand.At the heart of the airport elements of the SESAR concept is an evolution toward a more collaborative, performance based process of airport planning. In particular, SESAR calls for the identification and definition of those processes necessary for ensuring common planning, common situational awareness and a common performance framework for airport operations planning. In parallel the necessary decision support tools and procedures in support of these processes are required to be developed.The future SESAR Collaborative Airport Planning (CAP) approach will build on the Airport Collaborative Decision Making (A-CDM) [4], framework which is currently being implemented at a number of major European airports. A-CDM enables collaborative work between all airport partners through the sharing of relevant information notably relating to aircraft turnround milestones. The sharing of airborne flight progress information and departure planning information between the network and CDM equipped airports ensures a more accurate planning of network and airport resources due to timely and more accurate information. During implementation trails it has been found that an environment which ensures the availability of accurate data at the right time in the right place to airport partners who needs this information leads to improved predictability and thereby to improved resource allocation.Nevertheless, despite the improved data sharing, there still remains today the reality that operational decisions within an airport are implemented in such a way that the "solution" is limited to maximising the immediate interests of those making the decision. The aim of Total Airport Management (TAM) is to create an environment where operational decisions taken by any principal airport actor may be made in the full knowledge of the operational constraints and/or priorities of other actors who may be impacted by the decision. The management of degraded situations will be improved, coupled with a faster recovery to normal operations. The decision making process in this environment will be centered around an agreed performance framework as prescribed by SESAR.
