Impact Characteristics of Seat Back Mounted IFE Monitors - Basis for ARP6330

2018-09-13
CURRENT
AIR6908
This document provides background information, rationale, and data (both physical testing and computer simulations) used in defining the component test methods and similarity criteria described in SAE Aerospace Recommended Practice (ARP) 6330. ARP6330 defines multiple test methods uses to assess the effect of seat back mounted IFE monitor changes on blunt trauma to the head and post-impact sharp edge generation. The data generated is based on seat and IFE components installed on type A-T (transport airplane) certified aircraft. While not within the scope of ARP6330, generated test data for the possible future development of surrogate target evaluation methods is also included.

CURRENT
ARP6330
This SAE Aerospace Recommended Practice (ARP) defines means to assess the effect of changes to seat back mounted IFE monitors on blunt trauma to the head and post-impact sharp edges. The assessment methods described may be used for evaluation of changes to seat back monitor delethalization (blunt trauma and post-test sharp edges) and head injury criterion (HIC) attributes (refer to ARP6448 Appendix A Items 3 and 6, respectively). Application is focused on type A-T (transport airplane) certified seat installations.

Modification or Replacement of Components on Dynamically Certified Seat Systems

2018-02-06
CURRENT
ARP5497A
This document outlines the engineering evaluation appropriate for modifying or replacing components of a previously certified seat when the certification process is based on qualification to the requirements of AS8049, which includes dynamic testing. The engineering evaluation presented in this document may be used to determine if a modification (including replacement of a component) is a minor change with respect to meeting the dynamic testing requirements described in AS8049. Whenever a modification is considered, the ability to meet all requirements of the applicable Federal Aviation Regulation (FAR) must be verified. For example, this would include the capability to meet requirements such as flammability and flotation. Analysis and/or test data supporting the ability of the new materials and/or configuration to meet the applicable requirements must be submitted with the change documentation.

WIP
ARP6448A
This document provides an industry-recommended framework for establishing agreements to ensure that seats with integrated electronic components (e.g., actuation system, reading light, inflatable restraint, IFE, etc.) meet the seat TSO Minimum Performance Standard. These agreements will allow Seat Suppliers to build and ship completed, integrated and approved seat assemblies under TSOA with electronics included. The document presents the roles, responsibilities and accontibilities of the Electronics Manufacturer, the Seat Supplier, and the Seat Installer/Electronics Activator in the context of AC 21-49 Section 7.b ‘ Type Certification using TSO-approved seat with electronic components defined in TSO design’. This document applies to all FAA seat TSOs (C39(), C127()…etc).

Performance Standard for Seat Surrounding Furniture in Transport Aircraft

2017-09-19
WIP
AS6960
Seat surrounding furniture (commonly known as shells) is intended to enhance passenger comfort and privacy. They can offer additional space for reclining the seat into a bed position, additional stowage, amenities, etc. Often some amenities are located on the furniture including the front row monument installed in front of the passenger seat. The units normally attach to the same aircraft floor tracks directly in front or behind passenger seat(s) or to the seat primary structure. The unit structures are not directly integrated into the main fuselage and do not offer main supports for aircraft integrity. This Aerospace Standard (AS) establishes the minimum design, performance and qualification requirements for Seat Surrounding Furniture to be certified for installation in transport category airplanes.

Performance Standards for Oblique Facing Passenger Seats in Transport Aircraft

2017-06-28
CURRENT
AS6316
This SAE Aerospace Standard (AS) documents a common understanding of terms, compliance issues, and occupant injury criteria to facilitate the design and certification of oblique facing passenger seat installations specific to Part 25 aircraft. The applicability of the criteria listed in this current release is limited to seats with an occupant facing direction greater than 18° and no greater than 45° relative to the aircraft longitudinal axis. Seats installed at angles greater than 30° relative to the aircraft longitudinal axis must have an energy absorbing rest or shoulder harness and must satisfy the criteria listed in Table 2. Later revisions are intended to provide criteria for other facing directions. Performance criteria for forward and aft facing seats are provided in AS8049 and for side facing seats in AS8049/1.

ARP6199B

This SAE Aerospace Recommended Practice (ARP) is only applicable to 14 CFR part 25 Transport Airplane passenger seats. This document provides an approach for determining which parts on aircraft seats are required to meet the test requirements of 14 CFR part 25 Appendix F, Parts IV and V. Such materials are referred to as Heat Release Special Conditions (HRSC) compliant]. Additionally, it is recommended to use HRSC compliant materials in applications where not required.

Independent furniture related to seat installations is outside the scope of this document.
