This advisory circular (AC) sets forth an acceptable means, but not the only means, for demonstrating compliance with title 14 of the 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.
