CRD 2013-11

Regular update of CS-25

The specific objective of Notice of Proposed Amendment (NPA) 2013-11 (published on 10.7.2013) was to propose an amendment to CS-25 based on the selection of non-complex, non-controversial, and mature subjects. The ultimate objective is to increase safety.

NPA 2013-11 proposed amendments to existing and the creation of several new cabin safety-related Acceptable Means of Compliance (AMC), the creation of new security specifications and AMC for chemical oxygen generators, and the creation of two new appendices to AMC 25-11 ‘Electronic Flight Deck Displays’.

This Comment-Response Document (CRD) contains the comments received on NPA 2013-11 and the responses provided thereto by the Agency.

Based on the comments and the responses, Decision 2015/019/R was developed.


Cabin safety: Only one comment was received which did not lead to changes to the proposed text. Two slight changes were made by the Agency to the proposed AMC 25.793 and AMC 25.809.

Chemical oxygen generators: No comments received. Some changes were made by the Agency to the proposed text in order to achieve harmonisation with the FAA final rule and Advisory Circular.

Avionics: The proposed new appendices to AMC 25-11 (Appendix 6 ‘Head-Up Display’ and Appendix 7 ‘Weather Display’) attracted most of the comments. These comments, together with the consideration of the final FAA AC 25-11B, were used to bring some clarifications and improvements to the proposed text. Few differences still remain compared to the FAA AC, which reflect some rule differences.
