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

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


25.04.2007 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

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

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;


25.04.2007 9


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.

Other requirements depend on the intended operation CS AWO (All Weather Operation) for CAT I/II/III

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)


25.04.2007 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.


25.04.2007 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


25.04.2007 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

Overview Rulemaking Process


25.04.2007 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


25.04.2007 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


25.04.2007 17

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

NPA Process: InitiationNotice of Proposed Amendment


25.04.2007 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


25.04.2007 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


25.04.2007 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


25.04.2007 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


25.04.2007 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

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
