• ED Decision 2020/011/R found in: CS-ETSO Amdt 17 - European Technical Standard Orders (Oct 2026)

#### ETSO-2C176a *ED Decision 2020/011/R* ##### Aircraft Cockpit Image Recorder Systems **1 Applicability** This ETSO provides the requirements that aircraft cockpit image recorder (CIR) systems that are designed and manufactured on or after the date of this ETSO must meet in order to be identified with the applicable ETSO marking. **2 Procedures** 2.1 General The applicable procedures are detailed in CS-ETSO, [Subpart A](#_DxCrossRefBm920220672). 2.2 Specific All the information specified in EUROCAE ED-112A, Section 2-1, 2-1.3.4, excluding item 6, shall be documented in a manual and be made available to the accident investigation authorities on request. In addition, if special tools or recovery techniques are used to retrieve recorded information from any memory device used within the crash-protected memory module removed from a crash-damaged recorder, these tools/recovery techniques shall be also made available to the accident investigation authorities on request. Note: Requests from accident investigation authorities can be independent of any ongoing investigation. **3 Technical Conditions** 3.1 Basic 3.1.1 Minimum Performance Standard The applicable standards are those provided in the applicable sections of EUROCAE ED-112A, MOPS for Crash Protected Airborne Recorder Systems, dated September 2013 that pertain to the Cockpit Image Recorder (CIR) type, except chapters III-1 and III-6, and Sections 2-1.1, 2-1.5, 2-1.6, 2-1.11, 2-1.12, 2-3.1, 2-5, 3, Annex III-A, Annex III-B, and other ED-112A requirements related to aircraft-level equipment installation, flight testing, and aircraft maintenance as amended by Appendix 1 to this ETSO. The table below lists the types of recorder and the ED-112A section or part that contains the MPS for each of them: ***Table 1 — CIR MPS Requirements*** <table bgcolor="#d9d9d9" cellpadding="7" cellspacing="0"> <col/> <col/> <thead> <tr valign="top"> <td bgcolor="#808080"><p align="left"> <b>CIR Type </b> </p> </td> <td bgcolor="#808080"><p align="left"> <b>ED-112 Reference </b> </p> </td> </tr> </thead> <tbody> <tr valign="top"> <td bgcolor="#d9d9d9"><p align="left"> Single CIR in a non-deployable recorder</p> </td> <td bgcolor="#d9d9d9"><p align="left"> Section 2 and Part III. </p> </td> </tr> <tr valign="top"> <td bgcolor="#d9d9d9"><p align="left"> CIR function in a deployable recorder </p> </td> <td bgcolor="#d9d9d9"><p align="left"> Section 2 (except for tests covered by ETSO-2C517) and Part III.</p> <p align="left">The recorder shall also comply with ETSO-2C517.</p> </td> </tr> <tr valign="top"> <td bgcolor="#d9d9d9"><p align="left"> CIR function in a combined non deployable recorder </p> </td> <td bgcolor="#d9d9d9"><p align="left"> Section 2, Section 4 and Part III.</p> </td> </tr> <tr valign="top"> <td bgcolor="#d9d9d9"><p align="left"> CIR function in a <u>combined deployable</u> recorder</p> </td> <td bgcolor="#d9d9d9"><p align="left"> Section 2 (except for the tests covered by ETSO-2C517), Section 4 and Part I.</p> <p align="left">The recorder shall also comply with ETSO-2C517.</p> </td> </tr> </tbody> </table> Note: A CIR article may cover multiple types. A CIR may be a combined CIR and may also be deployable, in which case the applicable MOPS are in Sections 2, 4, Part I and the MOPS of ETSO-2C517, following the table above. 3.1.2 Environmental Standard See CS-ETSO, Subpart A, paragraph 2.1 3.1.3 Software See CS-ETSO, Subpart A, paragraph 2.2 3.1.4 Airborne Electronic Hardware See CS-ETSO, Subpart A, paragraph 2.3 3.2 Specific 3.2.1 Failure Condition Classification See CS-ETSO, Subpart A, paragraph 2.4. A failure of the function defined in paragraph 3.1.1 of this ETSO is a minor failure condition. A loss of the function defined in paragraph 3.1.1 of this ETSO is a minor failure condition. Note: The failure classification requirement is driven by the use of recorders in accident investigations. **4 Marking** 4.1 General See CS-ETSO, Subpart A, paragraph 1.2 4.2 Specific 4.2.1 Lettering Identification The equipment shall comply with the identification requirement in EUROCAE ED-112A, Section 2-1, paragraph 2-1.16.3, if it is fixed, and those of ETSO-2C517, if it is deployable. **5 Availability of Referenced Documents** See CS-ETSO, Subpart A, paragraph 3 [Amdt ETSO/6] [Amdt ETSO/13] [Amdt ETSO/16]
