Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 12 Operational Scenario Example OS-35 High density TMA Arrival – Flying CDA Merging Input from SESAR:  Section F3.5 of SESAR ConOps refers to aircraft that "as far as possible, fly their individual optimum … descend profiles" in medium/low complexity TMAs  Section H2.3 of SESAR ConOps refers to high complexity TMAs where a trade-off between throughput, punctuality and environmental performances will be made  The Operational Improvement steps (OI-steps) addressed are - AOM-0701 Continuous Descent Approach (CDA) - AOM-0702 Advanced Continuous Descent Approach (A-CDA)

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 13 Operational Scenario Example Input from early interim DOD G-General:  Contained initial high level CDA scenario “Flying CDA merging without Structured Routes” Input from additional sources used (EUROCONTROL and ICAO documents, European and international studies) Operational Scenario was composed:  The TMA described in this scenario consists of medium/low complexity and high traffic density  Aircraft have ATM Service and Capability Level 2, scenario is set around 2015 time frame

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 14 Operational Scenario Example The CDA scenario is set in a Point Merge airspace structure Scenario describes the processes and interactions between human actors and systems for the following cases:  Nominal CDA procedure  CDA procedure with tactical ATC controller intervention  CDA procedure with wind impact IAF

Brussels, 13 & 14 Oct 2009 Episode 3 - CAATS II Final Dissemination Event 15 Operational Scenario Example Scenario was updated with Episode 3 Validation Exercise results and comments from Episode 3 TMA Expert Group Scenario contains hop topic discussion boxes with open issues. Example from case with tactical intervention:  Hot Topic: How can the CTA and RTA of an aircraft be revised?  Expert discussion: Next generation of AMAN tools should dynamically and continuously compute revised CTA and a place in the arrival sequence Scenarios will be disseminated as an annex of Detailed Operational Descriptions
