Objective of Concept Detailing

Supporting validation activities- Concept descriptions for exercises

Process ModelDetailed Operational Descriptions

DODs

Operational Scenarios

Storyboards

• Support implementation of SESAR Target Concept Production of specifications

- Need comprehensive coverage- Sufficient level of detail- Future OSED production

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

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

General Development Process

Operational Scenarios (OS)27 OS developed within Episode 3

SESAR sources e.g. Concept of Operations (SESAR D3),

Operational Improvement Steps (SESAR D5)

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)

• 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

• 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

• 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

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

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
