Document Title: AC 20-146A Methodology for Dynamic Seat Certification by Analysis for Use in Parts 23, 25, 27, and 29 Airplanes and Rotorcraft
Summary: This advisory circular (AC) sets forth an acceptable means, but not the only means, for demonstrating compliance with Title 14, Code of Federal Regulations (14 CFR) 23.562, 25.562, 27.562, and 29.562, as well as Technical Standard Order (TSO) TSO-C127a, and TSO-C127b. This AC includes guidance for certifying seats by computer modeling analysis techniques that are validated by dynamic tests. This AC defines the acceptable applications, limitations, validation processes, and minimum documentation requirements involved when substantiation by computer modeling is used to support a seat certification program.

Document Title: Guidelines for Design Approval of Aircraft Data Link Communication Systems Supporting Air Traffic Services (ATS)
Summary: This AC provides guidance material for applicants seeking an airworthiness approval for aircraft with an installed data link system intended to support air traffic services (ATS) data communication. It identifies specific configurations of aircraft data link systems for applicants seeking approval for type certificates (TC) and supplemental type certificates (STC) in order to facilitate operational approvals. Appendix B of this AC provides a list of related documents. Appendix C of this AC contains a list of applicable acronyms. This AC describes an acceptable means, but not the only means, for you to gain airworthiness approval for aircraft data link system equipment. However, if you use the means described in this AC, you must follow it in all important respects.

Document Title: Onboard Recording of Controller Pilot Data Link Communication In Crash Survivable Memory
Summary: This advisory circular (AC) provides guidance material for applicants seeking an airworthiness approval for aircraft with an installed Data Link Recording (DLR) system that records Controller Pilot Data Link Communications (CPDLC). This AC describes an acceptable means, but not the only means, to gain design approval of your data link communication recording system. However, if you use the means described in the AC, you must follow it in all important respects.
In this AC, we focus on data to be recorded and logical recording point locations for storing CPDLC messages in onboard crash-survivable memory. These logical point locations, also called observation points, are physical locations within airborne avionic architectures deemed ideal for recording system data sources.
