Australian Technical Standard Order C1007b — flight data recorder interface unit
1 Name of instrument
1.1 This instrument is the Australian Technical Standard Order C1007b Instrument 2014.
1.2 This instrument may be referred to as Australian Technical Standard Order C1007b, or ATSO-C1007b.
1.3 In this instrument, the instrument itself is also referred to as “this ATSO”.
This instrument commences on the day after registration.
This instrument prescribes the minimum performance standards (MPS) which a flight data recorder interface unit (FDRIU) must meet to:
(a) obtain an Australian Technical Standard Order (ATSO) authorisation or letter of design approval; and
(b) be identified with the applicable ATSO marking.
4.1 This ATSO is effective for authorisation applications submitted after the commencement of this ATSO.
4.2 For this instrument, the effective date is the commencement of this instrument.
4.3 To avoid doubt, all of the requirements set out in Appendix 1 to this instrument are the MPS for a FDRIU.
Appendix 1 Flight Data Recorder Interface Unit (FDRIU) requirements
The requirements for an FDRIU are as follows
1 Equipment Standards
(a) System requirements
(i) An FDRIU must process Parameters 1 - 6 of Appendix 1 of Civil Aviation Order (CAO) 103.19. An FDRIU may optionally process Parameters 7 – 20 of Appendix 1 of CAO 103.19.
(ii) All processed parameters of the FDRIU must meet the ranges, accuracy and maximum recording intervals specified in Appendix 1 of CAO 103.19.
(iii) All parameters of the FDRIU must be sampled, conditioned, and digitised or reformatted in such a manner as to meet ARINC 717-15 standard signal characteristic.
The standards set out in this ATSO apply to an FDRIU that is:
(i) airframe mounted; and
(ii) functioning as an interface between analogue aircraft systems and digital flight data recorders (DFDR).
(c) Failure condition classification
The applicant must ensure the FDRIU has a design assurance level commensurate with the failure condition classification of “Minor”.
Note 1: Failure condition classification “Minor” is in alignment with the failure classification of TSO-C124b - Flight Data Recorder System, dated 10 April 2007.
Note 2: For a definition of failure condition categories refer to United States Federal Aviation Administration (FAA) Advisory Circular (AC), System Design and Analysis AC 25.1309-1A, Equipment, Systems and Installations in Part 23 Airplanes AC 23.1309-1D or later amendments; or European Aviation Safety Authority (EASA) System Design and Analysis Acceptable Means of Compliance (AMC) 25.1309 or later amendments.

(e) Software qualification
FDRIU software must be developed in accordance with RTCA Document RTCA/DO-178C - Software Considerations in Airborne Systems and Equipment Certification, dated 13 December 2011,or later version in force at the time of development. Software implementing the functions defined in
this ATSO must be developed to Level D, categorised as minor failure condition specified in Section 2.3.3 of RTCA/DO-178C.
(f) Electronic Hardware Qualification
FDRIU complex hardware must be developed in accordance with RTCA/DO-254 - Design Assurance Guidance for Airborne Electronic Hardware, dated 19 April 2000, or later version in force at the time of development.

(g) Fire Protection
All materials used in the manufacture of an FDRIU must be self-extinguishing in the event of fire, other than small parts that would not contribute significantly to the propagation of fire. For this purpose, any materials used in the FDRIU must meet the requirements of Category C of Section 26 as defined in RTCA Document RTCA/DO-160F - Environmental Conditions and Test Procedures for Airborne Equipment dated 6 December 2007 or later version in force at the time of manufacture.
For subregulation 21.609 of CASR 1998, CASA may, on request, issue an approval for a deviation from any performance standard mentioned in this ATSO.
Note: CASA may approve use of alternative or equivalent means of compliance to the Equipment Standards set out in this Appendix. Applicants must demonstrate that an equivalent level of safety is maintained. Requests and approval must be in accordance with regulation 21.609 of CASR1998.
2 Marking requirements
(a) An FDRIU manufactured in accordance with this ATSO must be marked in accordance with paragraph 21.607 (1) (c) of CASR 1998.
(b) Each separate component of an FDRIU must be permanently and legibly marked with at least the following:
(i) the name of the manufacturer; and
(ii) the number “ATSO-C1007b”.
3 Data requirements — application data
