Review Process

• DODs Reviewed by Experts
• Current Operations in ANSPs, ATFCM, Airlines,
  Military
• SESAR Definition Phase CONOPS (222)
• Some new material added through review
• Early user of Review Room
• Allowing potentially contradictory comments to be
  easily identified
• Hot topics identified debated
• Via Email difficult to record transparency v
  spam effect
• Via Discussion Room good
• Answers by Exercises or escalated to
  Co-ordination Cell
• Development of a Lexicon
• Developed agreed definitions for over 20 SESAR
  terms
• Available as document and on www.episode3.aero

Additional Concept Detail

• Lexicon Definitions
• Paraphrasing text from 222
• Target Time of Arrival, Shared Business
  Trajectory, Revision
• Proposed in Episode 3
• Arrival Management, Constraint, Tolerance Window
• New text in the DODs
• SBT to RBT agreement
• 222 gives time, Episode 3 proposed set of
  conditions
• New Roles and Descriptions of Responsibilities
• Airport driver role, complexity manager
  responsibilities
• Hot Topics deferred for S-JU activities
• Successive authorisation v increased workload
  AUO-0302
• Extent and meaning of CDM in execution phase
  222/D.2

DODs, Scenarios Storyboards

• DODs
• Specifications of main ATM processes
• Operational Scenarios
• Descriptions of how processes work together in an
  operation
• Operational scenarios fundamental to expert
  groups, prototyping and gaming
• Importance increased over time v Use Cases

• Storyboards
• Diagrammatic representation of parts of ATM
  operations
• Developed or reviewed in Expert Groups
• New in Episode 3

• Concept wide view
• now
• Zoom in to the TMA

General Development Process

• Operational Scenarios primarily developed to meet
  Episode 3 Validation Exercise needs
• Update with Episode 3 validation exercise results
  and Episode 3 Expert Group comments where
  available

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)

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

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

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

17
Lessons Learnt

• No Concept Authority
• Same topic discussed repeatedly
• But discussion needed for understanding
• Difficult to integrate exercise results
• Process defined, but difficult to agree
  responsibilities
• Consistency across DODs, Scenarios Storyboards
• In progress at the moment
• Hot Topics identified described
• Difficult, contentious or ambiguous problems
• Resolution, escalation or deferred for SESAR-JU
• Review Room and Discussion Room
• Management of discussion
• Debates recorded

18
Conclusions

• Developed a Concept Detailing Process
• ATM Process Model DODs
• Operational Scenarios Storyboards
• Checks for completeness coherence
• Identification of Hot Topics
• Concept detailing started from SESAR D3
• Input from operational experts (incl airlines)
• DODs, Scenarios and Storyboards available
• Lessons Learnt
