Friedhelm Runge EASA, Parts & Appliances Section

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

3. From Demonstration of Function into Operation
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

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 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 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: Initiation Notice 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 months although 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
