Scope
This SAE Aerospace Recommended Practice (ARP) defines a means of assessing the credibility of computer models of aircraft seating systems used to simulate dynamic impact conditions set forth in Title 14, Code of Federal Regulations (14 CFR) Parts 23.562, 25.562, 27.562, and 29.562. The ARP is applicable to lumped mass and detailed finite element seat models. This includes specifications and performance criteria for aviation specific virtual anthropomorphic test devices (v-ATDs). This document provides a recommended methodology to evaluate the degree of correlation between a seat model and dynamic impact tests. This ARP also provides best practices for testing and modeling designed to support the implementation of analytical models of aircraft seat systems. Supporting information within this document includes procedures for the quantitative comparison of test and simulation results, as well as test summaries for data generated to support the development of v-ATDs and a sample v-ATD calibration report.
Rationale
The changes in this revision represent the latest agreement obtained by the SAE SEAT Committee to provide the most current information on the topic. This revision adds details on the ES-2re ATD, recommendations on how to document the certification approach, and an analysis checklist. Preexisting sections of the document have been revised to improve clarity and provide additional information or correct errors.

Issuing Committee
The Aerospace Council of SAE established the Aircraft Seat Committee (SEAT) in 1997 to address technical issues related to the design and/or performance of aircraft seating systems. The seating systems include crew, flight attendants, and passenger seats installed in Civil Rotorcraft, Transport Aircraft, and General Aviation Aircraft.
A list of the technical reports developed by the SEAT Committee can be obtained by searching on 'aircraft seat' and selecting 'standards', from the SAE Home Page. SEAT StandardsReference

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
