European Aviation Safety Agency Aircraft Certification Principles 1/3 Q 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. Q 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 8

European Aviation Safety Agency Aircraft Certification Principles 1/3 Q 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. 25. 04. 2007 9

European Aviation Safety Agency Aircraft Certification Principles 3/3 Q Other requirements depend on the intended operation ò CS AWO (All Weather Operation) for CAT I/II/III automatic landing ò AMC 20 -4 B-RNAV Navigation ò (AMC 20 -to come) JAA TGL 10 P-RNAV Navigation ò (AMC 20 -to come) ADS-B NRA Use of ADS-B for separation in Non Radar Airspace ò Airspace use (8. 33 k. Hz, Mode S) ò Commercial Operation (2. /3. System) 25. 04. 2007 10

European Aviation Safety Agency Certification Need? Q Any design change to an aircraft model Q needs certification. ò 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 11

European Aviation Safety Agency Certification Requirements for ADS -B NRA as provided from RFG in ED -126 to allow interoperability Q Failure classification for ADS-B NRA application Q Integrity Requirement for the ADS-B NRA application Q Transmitted Data: Position information + quality indicators from GNSS source meeting ETSO or equivalent standard Q Data Quality: Maximum delay time for the position information Q Data Format: Use of ED-102/DO-260 or DO-260 A for ADS-B data computation 25. 04. 2007 12

European Aviation Safety Agency Certification Result Q Documentation that requirements are met Q Statement visible to pilots and inspectors Q Documentation of accepted noncompliances and associated restrictions Q Basis for airborne use of the function 25. 04. 2007 13

European Aviation Safety Agency Overview Rulemaking Process 25. 04. 2007 14

European Aviation Safety Agency Programming (process) Q Executive Director (ED) establishes annual rulemaking program Q He consults SSCC and AGNA Q any person may propose issues Form Q Programme supported by preliminary RIA (Regulatory Impact Assessment) Q ED can adapt the program Q Publication of program Q Regular review of the impact of rules 25. 04. 2007 15

European Aviation Safety Agency Programming in practice Q The general approach for the development of Year N Rulemaking programme and the advance planning is briefly explained here: ò 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 ò 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 16
