Document Title: Airborne Software Assurance Topics
Summary: This AC provides guidance to help you comply with the software aspects of the applicable airworthiness regulations and is in addition to the assurance processes described in DO-178C and DO-178B. Most of the guidance contained in this AC has been extracted from FAA Order 8110.49 change 1, Software Approval Guidelines, and from issue papers that have been applied to specific type certification programs. If you are using DO-178C or DO-178B (hereafter referred to as DO-178C/B) for software assurance, you should determine which chapters apply to your project, and use the guidance contained therein.

Document Title: Dynamic Evaluation of Seat Restraint Systems and Occupant Protection on Transport Airplanes
Summary: Change 1 to AC 25.562-1B would remove guidance that allowed certain methods for showing compliance with 14 CFR 25.562(c)(5). These methods were issued in error and have resulted in conditions where the full required range of occupants might not have the same level of head injury protection. They also conflict with existing FAA policy.

Please note that this proposed change affects pages 12, 19, 20, 74, and 75 of AC 25.562-1B. We have posted and are requesting comments on these pages only. For reference, you can find the complete version of AC 25.562-1B (without the changed pages) on the Internet at http://www.faa.gov/regulations_policies/advisory_circulars/.

Please note that as of April 17, we have posted an updated version of the proposed AC. It corrects paragraph numbering errors on pages 20 and 74. No changes were made to the technical content.
