AIR TRAFFIC FLOW MANAGEMENT AND FLEXIBLE USE OF AIRSPACE
Contents Concept of ATFM and FUA Timeline of Implementation Why is FUA required ATFM and FUA About ATFM in India CDM Partners involved in processes Benefits of FUA ATFM and FUA- Practical Process
Fundamental principle of FUA The airspace should not be designated as either pure civil or military airspace, but rather be considered as a continuum in which all user requirements have to be accommodated to the extent possible . AIRSPACE RESOURCES BECOME AVAILABLE ON NEED BASIS TO THE STAKEHOLDERS
PROCESS of ATFM Develop Identify strategies to constraints in mitigate • ATFM is a the system constraints collaborative process ATC involving many stakeholders with Multi- Flight diverse goals. national Operators Collaborate (ICAO) TFM Monitor with service • CDM enables the system status providers and and demand stakeholders on solutions stakeholders to share Airport the resources Military Operators optimally. Implement Analyze post- and manage operation actions
ASBU B0-NOPS Requirements • Provide a solid foundation • Improved ATFM and ATFM- for regulating traffic flow AO integration • Predict demand and • Synchronization capacity including • Initial User Driven quantified uncertainty Prioritization Process measures (UDPP) • Full Flexible Use of Airspace (FUA) • Complexity Management

Concept and FUA Timeline The Flexible Use of Airspace (FUA) Concept has been developed at the three Levels of Airspace Management that correspond to Civil/Military co-ordination task. STRATEGIC COMPONENT ( ASM Level 1 ) Long term planning – large scale military exercises, significant changes to airspace and route structure and special events. This includes but is not limited to Airshows, Large Scale Events, Trade Fairs, etc. PRE-TACTICAL COMPONENT ( ASM Level 2) Airspace users engaged in normal operations e.g.: Aerial Surveys, Para Drop, Fly Past ; Activation of SUAs TACTICAL COMPONENT ( ASM Level 3) Day to day flight operation.
ASM LEVELS and ATFM Stages ASM Level 1 Strategic ATFM Strategic Level PLANNING ; Establishment of pre-determined Network airspace structures Operations Plan ASM Level 2 CCC and Local Pre-tactical Level FMP ; Impact Day-today allocation of airspace Analysis and according to users’ requirements DAP ASM Level 3 CCC & Local Tactical Level FMP ; ATFM Real-time use of airspace allowing measures a safe OAT/GAT separation
Why is FUA required? To ensure all stakeholders affected have full understanding of operations and requirements. ATC-Military. To ensure airspace users have sufficient notice of operations via NOTAMs / Supplements. Air traffic planning, efficient flow of air traffic. Equal airspace usage.

ATFM AND FUA • Network Wide View Shared • Both ASM and FUA will focus on : • Enhanced airspace utilisation by civil and between Civil and Military military • Focus areas of cooperation • Airspace Configurations – Inclusion of future civil/military airspace • ASM solutions requirements • Procedures – Enhanced cooperation in crisis and • Enhanced cooperation at pre-tactical and contingency situations tactical level – ASM system support and data • management Getting closer together planning and – operations ASM Post Ops and Performance Monitoring • Integrating ASM/ATFCM • Flexible Route deployment in the Upper Airspace
AAI CENTRAL ATFM STRUCTURE • Objective is to manage and optimize WEB PORTAL traffic flows by actively collaborating ATFM with airlines, airport, defense and other Command stakeholders on daily basis.

FUA Elements • Temporary reserved area (TRA) :An airspace temporarily reserved and allocated for the specific use of a particular user during a determined period of time and through which other traffic may be allowed to transit ATC Clearance. • Temporary segregated area (TSA) :An airspace temporarily segregated and allocated for the exclusive use of a particular user during a determined period of time and through which other traffic will not be allowed to transit. • Conditional Routes : A conditional route is a non-permanent ATS route or portion thereof which can be planned and used under specified conditions
