3. Modernization of the OLS Briefing to ANC 15 Sep 2017

4. Job Card • The 12th Air Navigation Conference and the 38th ICAO Assembly called for a significant review of the Annex 14 Obstacle Limitation Surface (OLS) and for guidelines to be developed for conducting aeronautical studies to assess permissible penetrations; • Job card ADOP003 titled “Obstacle Limitation Surfaces at Aerodromes.” was issued and the OLSTF was set up to undertake the review; • The task force reports to both ADOP and IFPP; • Work to be completed by Sep 2018 to meet the Effective Date of 2020; • The Applicability Date has been set for 2024.

5. Need for Change • Inconsistency between OLS and modern aircraft performance; • Inconsistency between Annex 14, Annex 6 and PANS OPS; • OLS are not updated to protect new flight procedures and operations • Increasing competition between safety and economic considerations at aerodrome and its vicinity; • Lack of guidelines for conducting aeronautical studies.

6. Concepts • Obstacle Free Surfaces (OFS) • Surfaces that are applied within a defined airspace to be maintained free from obstacles; • Obstacle Evaluation Surfaces (OES) • Surfaces that are applied in a defined airspace, below and beyond the OFS, to be evaluated against obstacles;

7. OFS - Characteristics • The OFS shall not be penetrated; • The new surfaces are expected to be less restrictive i.e. narrower, steeper and shorter; • This segment of the airspace is deemed critical to the safety of flight operations and shall be maintained free from obstacles

8. OES - Description • The Obstacle Evaluation Surfaces are additional surfaces that are applied in a defined airspace, below and beyond the OFS, to be evaluated against obstacles. • The purpose of the Obstacle Evaluation Surfaces is to determine the acceptability of obstacles by evaluating their impact to planned or existing operations outside the OFS, both on safety and regularity. • The OES act as a trigger for an aeronautical study which will evaluate the potential impact of obstacles to planned or existing aeroplane operations outside the OFS. The penetration may be acceptable when after the aeronautical study it is determined that the object would not adversely affect the safety or significantly affect the regularity of operations of aeroplanes;

9. Aeronautical Study • An aeronautical study is a process of examining an aeronautical concern in order to assess its impact and identify, if need be, possible mitigations not adversely affecting the safety and regularity of aircraft operations; • The aeronautical study processes, to be described in the PANS-ADR, can be categorized into the following stages: • Identifying the hazards; • Possible mitigations • Impact (cost, efficiency and safety) associated with the mitigations • Recommendation for acceptance of the aeronautical study • The framework and eventually the guidance to be developed by the OLSTF focuses on flight operations. However, we recognised that there are other aspects of aviation that need to be considered in the aeronautical study. These areas include: • Impact to CNS • Impact to ATC Operations e.g. loss of Line of Sight • Aerodrome Operations (Usability, Accessibility and Efficiency) • Environmental

10. Data Analysis • For the design of OFS • FAA tracks (DGAC/STAC, confidential agreement) • 35 US airports equipped with ASDE-X system

11. Data Analysis • 135000 approach trajectories • Evaluate the 10-7 or 10-8 containment surfaces associated with… • Straight-in approaches • With a glide slope of 3° • For all four AAC, on non-instrument and instrument operations => Identify a width, a slope and a divergence

12. Data Analysis • 61268 departure trajectories • Evaluate the 10-7 or 10-8 containment surfaces associated with… • Straight-out departures • For all four AAC, => Identify a width, a slope and a divergence => See if the approach surface could be satisfying

13. Data Analysis • Go-around trajectories • For the design of the transitional surface

14. Implementation – Impact to States • Existing regulations / zoning laws need to be amended; • Workflow changes; • Mindset change; • Increase in workload.

15. Implementation Challenges • Developing a correlation between ARC and AAS; • Developing SARPs; • Developing PANS-ADR provisions; • Coordination with other panels, working group and task force.

16. Implementation Strategy • The changes will bring about a paradigm shift in how airspace protection is understood. Effort is needed to explain, train and mentor States to help them transit to these new surfaces. The group suggests the following tasks to assist States in the implementation:- • Circular to explain the concepts; • Workshops both at global and regional level to socialize these concepts ;and • Training kit to help States develop the new surfaces at the aerodromes.

17. Timeline • Circular by the end of 2018; • SARPs by 2020, effective 2022, applicable 2026; • Update the job card.
