The Panoply of Systems Engaged in Flow Management Tool Name Brief Description Comment Airport – Collaborative Concept and system focused on Concept has milestones that allow networking of Decision Making (A-CDM) Airport efficiency airports. SMAN (see below) functionality a part of the concept. Arrival Manager (AMAN) Delivers a smoothed and Nominally an ACC-based system with TMA optimized traffic flow to the TMA displays. Currently not interfaced to the ATFM solution. Departure Manager (DMAN) Provides efficient flow over Coordinates multiple departure airports congested departure fixes delivering to a common fix – nominally ACC- or TMA-based. Surface Manager (SMAN) Manages aerodrome surface Controls startup/push back on an airport surface queues – nominally a tower cab system. Air Traffic Flow Management Manages airspace and aerodrome Functions in the pre-tactical and tactical (ATFM) Platform (e.g. Metron loading and provides fuel efficient timeframes – network management center based. Harmony) absorption of necessary delay Related Systems Tower Cab Automation Integrates displays and controls Tower cab centric system – tower cab interface to for efficient tower cab functioning GDP/AFP/SMAN/DMAN function. TMA ATM Platform Provides terminal area tactical TMA facility-based – generally no flow control automation management functions. ACC ATM Platform Provides ACC tactical control ACC-based – Can provide CHI for AMAN automation advisories. Page 2
Integration of Flow Management Tools • Maximizing the use of airspace and aerodrome resources and providing for fuel efficient delay absorption requires integration of these capabilities. • The ATFM platform is the right location for the integration functions: • ATFM operates over the full spectrum of operational time phases. • ATFM Dynamic Demand/Capacity Balancing operates with the best available information. • As the day and hour of the operation approaches, the accuracy of flight data improves. • Tactical Decision Support Tools (e.g., A-CDM, DMAN, AMAN) operate in smaller time horizon on the day of operation and with only localized information.

Summary • Maximizing the use of airspace and aerodrome resources and providing for fuel efficient delay absorption requires integration of Traffic Flow Management capabilities. • The ATFM platform provides a vehicle for achieving this integration. Page 5
