1. EASA Airborne Separation Assistance Systems (ASAS)Certification Friedhelm Runge EASA, Parts & Appliances Section friedhelm.runge@easa.europa.eu

2. Overview • From Demonstration of Function into Operation • Involved Parties • EASA Certification Principles • EASA Rulemaking process

3. Test Phase Installation is optional and the function is “testing” No or limited interaction with other aircraft or ATM, standard procedures stay in place Interaction limited to test participants Operational Phase Even optional the function is used for a safety critical function e.g. separation and must meet defined requirements Defined interaction with ATM Aircraft is eligible if certified for the defined function Certification can be demonstrated e.g. through AFM statement From Demonstration of Function into Operation

4. Involved Parties 1/2 • Requirement Focus Group: Define Function e.g. Separation in Non Radar Airspace using ADS-B. Assign Requirements to parties • Airspace Regulator (States coordinated through EUROCONTROL in future European Commission within Single European Sky Air Traffic Management SESAM) defines framework for Air Traffic Service Provider and airspace users • ATS offers service

5. Involved Parties 2/2 • Aircraft / Equipment manufactures to design airborne system • Standardised function through certification (EASA, FAA,… - State of Registry) • Operational Procedures implemented through Operational requirements e.g. EU-OPS and implemented through National home Authority of the operator • Pilot Training and Licensing under overview of National home authority

6. EASA responsibilities as defined today • “Rulemaking” for European Member States + Norway, Iceland, Bulgaria, Romania, Switzerland as defined in Basic Regulation EC 1592/2002 and related implementation regulations EC 1702/2003 and 2042/2003 in the area of aircraft design, production and maintenance • Certification of Aircraft and Design Organisations • Standardisation of National Authorities and coordination of SAFETY ASSESSMENT OF FOREIGN AIRCRAFT (SAFA) program

8. Aircraft Certification Principles 1/3 • Requirements defined per aircraft (CS 25, CS 23, CS VLA) or rotorcraft (CS 29, CS 27, CS VLR) weight and passenger capacity. Requirements cover minimum needed for safe flight. • CS 25.1301 Function and installation:Each item of installed equipment must –(a) Be of a kind and design appropriate to its intended function;

9. Aircraft Certification Principles 1/3 • CS 25.1309 Equipment, systems and installations(a) The aeroplane equipment and systems must be designed and installed so that:(1) Those required for type certification or by operating rules, or whose improper functioning would reduce safety, perform as intended under the aeroplane operating and environmental conditions.(2) Other equipment and systems are not a source of danger in themselves and do not adversely affect the proper functioning of those covered by sub-paragraph (a)(1) of this paragraph.(b) The aeroplane systems and associated components, considered separately and in relation to other systems, must be designed so that –(1) Any catastrophic failure condition (i) is extremely improbable; and (ii) does not result from a single failure; and(2) Any hazardous failure condition is extremely remote; and(3) Any major failure condition is remote.

10. Aircraft Certification Principles 3/3 • Other requirements depend on the intended operation • CS AWO (All Weather Operation) for CAT I/II/III automatic landing • AMC 20-4 B-RNAV Navigation • (AMC 20-to come) JAA TGL 10 P-RNAV Navigation • (AMC 20-to come) ADS-B NRA Use of ADS-B for separation in Non Radar Airspace • Airspace use (8.33 kHz, Mode S) • Commercial Operation (2./3. System)

11. Certification Need? • Any design change to an aircraft model needs certification. • Example for Design Change: New software, additional interface, new functionality • Use of ADS-B for ATC separation in a Non Radar Area is a new functionality having specific requirements => Airworthiness certification approval is needed for the installation design on the specific aircraft model.

12. Certification Requirements for ADS-B NRA as provided from RFG in ED-126 to allow interoperability • Failure classification for ADS-B NRA application • Integrity Requirement for the ADS-B NRA application • Transmitted Data: Position information + quality indicators from GNSS source meeting ETSO or equivalent standard • Data Quality: Maximum delay time for the position information • Data Format: Use of ED-102/DO-260 or DO-260A for ADS-B data computation

13. Certification Result • Documentation that requirements are met • Statement visible to pilots and inspectors • Documentation of accepted non-compliances and associated restrictions • Basis for airborne use of the function

14. Overview Rulemaking Process

15. Programming (process) • Executive Director (ED) establishes annual rulemaking program • He consults SSCC and AGNA • any person may propose issues Form • Programme supported by preliminary RIA (Regulatory Impact Assessment) • ED can adapt the program • Publication of program • Regular review of the impact of rules

16. Programming in practice • The general approach for the development of Year N Rulemaking programme and the advance planning is briefly explained here: • 1.The inventory of all rulemaking tasks is presented/ • At the AGNA (Advisory Group of National Authorities) and SSCC (Safety Standards Consultative Committee) meeting in November Year N-2 requesting their comments for March Year N-1 • In parallel to the FAA to establish a list of subjects for joint action • 2. The Year N programme is adopted in July of Year N-1 and two documents are produced: • the Year N Rulemaking programme: • Contain deliverables that commit the Agency • Year N Advance Planning: • Give an indication of the task that are either on-going or will start in the year but will not be finished in that year

17. NPA Process: InitiationNotice of Proposed Amendment Draw up Terms of Reference after consulting SSCC and AGNA • definition of task • timetable • format of deliverable • Choose between drafting group or Agency resources • If drafting group: ED decides composition after consulting SSCC and AGNA • Agency to provide support to groups

18. NPA Process: Drafting • ED may amend ToR • ED to verify that drafting result satisfies ToR • Assign unique NPA reference code • Publish NPA, including • proposed rule • explanatory note • significant, contentious or interface issues • situation with respect to ICAO and non-EU AA • full RIA

19. Regulatory Impact Assessment • What: decision support process • Why: improve quality of regulation • How: clarify positive and negative impacts • Safety, • Economic, • Environmental • Social • Other aviation requirements • form not prescribed • model provided • RIA proportionate to the likely impact

20. NPA Process: Consultation • Any person may comment • Consultation period: 3 monthsalthough ED may decide on different period • extensions can be granted only in exceptional cases • Comments shall contain: • identification of the comment provider • NPA reference code • position with justification

21. NPA Process: Review of comments • Comments review by original drafter(s) AND experts not involved in the drafting • Comment response document (CRD) to be published 3 months after consultation for 2 month • above period can be amended • if significant differences: ED may decide to re-circulate • if major objections from NAA’s (for rules to be applied by MS), ED shall consult AGNA

22. NPA Process: Adoption and publication • ED will issue decision not earlier than 2 months after publication of CRD • Rules + explanatory memorandum to be published in Agency’s Official publication

23. Flow - Chart

24. Summary • EASA is only one partner with limited tasks • The Intended Function has to be well defined • The assignment of responsibilities between the involved partners must be clear • Interfaces must be defined properly • Rulemaking is not a short term action
