The goal of this SAE Aerospace Recommended Practice (ARP) is to promote a common understanding of terms, compliance issues and design criteria in order to facilitate certification of seat installations in an aircraft. This document does not specify specific designs or design methods for such certification.

This SAE Aerospace Recommended Practice (ARP) documents a common understanding of terms, compliance issues, and design criteria to facilitate certification of seat installations specific to Part 25 aircraft. This ARP provides general guidance for seats to be installed in Part 23 aircraft and Parts 27 and 29 rotorcraft and does not specify specific designs or design methods for such certification.

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.

Part I of this document relates to the restraint systems for the flight deck crew. Part II considers restraint systems for other crew members, including cabin attendants. The recommendations herein include coverage of such items as harness reels, shoulder harnesses, and safety belts. However, the intention is not to limit the design of restraint devices to these particular system components only. These recommendations apply primarily to forward-facing seats. However, the design must take into account the fact that loads may be applied from any direction and be of a magnitude at least as great as those specified in current FAR's.

Part I of this document relates to the restraint systems for the flight deck crew. Part II considers restraint systems for flight attendants and other crew members. As applicable, the same criteria should be incorporated in both Part I and Part II installations. The recommendations herein include coverage of such items as harness reels, shoulder harnesses, and safety belts. However, the intention is not to limit the design of restraint devices to these particular system components only. These recommendations apply primarily to forward-facing and aft-facing seats. However, the design should take into account the fact that loads may be applied from any direction and be of a magnitude at least as great as those specified in current FAR's.

This SAE Aerospace Recommended Practice (ARP) defines additional documentation, environmental considerations, in-service damage limits, test and evaluation criteria necessary to support certification of aircraft seats manufactured using composite materials, in addition to requirements in AS8049 and ARP5526. This document is limited to aircraft seat composite parts in the seat primary load path from the occupant to the attachments of the seat to the aircraft. The term “composite” is inclusive of any fiber-reinforced polymer matrix materials such as carbon fiber-reinforced plastics, sandwich panels and bonded structure.

This SAE Aerospace Recommended Practice (ARP) provides a framework for establishing methods and stakeholder responsibilities to ensure that seats with integrated electronic components (e.g., actuation system, reading light, inflatable restraint, inflight entertainment equipment, etc.) meet the seat TSO minimum performance standard. These agreements will allow seat suppliers to build and ship TSO-approved seats with integrated electronic components. The document presents the roles and accountabilities of the electronics manufacturer (EM), the seat supplier, and the TC/ATC/STC applicant/holder 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. The document defines the roles and responsibilities of each party involved in the procurement of electronics, their integration on a TSO-approved seat, and the seat’s installation on an aircraft.

This document provides an industry recommended framework for establishing a multi-party agreement to support approval of electronic components (e.g., actuation system, reading light, inflatable restraint, IFE, etc.) integrated in aircraft seats and provide a framework that allows seat manufacturers to build and ship completed, integrated, and approved seat assemblies with electronics included. The primary purpose of this document is to provide roles, responsibilities and accountabilities to meet AC 21-49 Section 7.b ‘Type Certification using TSO-approved seat with electronic components defined in TSO design’. This document may be applied to all applicable seat TSOs (C39(), C127()…etc). The approval for the integration of the electronics will fall, in part or in full, under the type design authority of the Seat Installer rather than the Seat Supplier shipping the integrated seat.

This document provides informational background, rationale and a technical case to allow consideration of the removal of the magnesium alloy restriction in aircraft seat construction as contained in AS8049B. The foundation of this argument is flammability characterization work performed by the FAA at the William J. Hughes Technical Center (FAATC), Fire Safety Branch in Atlantic City, New Jersey, USA. The rationale and detailed testing results are presented along with flammability reports that have concluded that the use of specific types of magnesium alloys in aircraft seat construction does not increase the hazard level potential in the passenger cabin in a post-crash fire scenario. Further, the FAA has developed a lab scale test method, reference DOT/FAA/TC-13/52, to be used as a certification test, or method of compliance (MOC) to allow acceptability of the use of magnesium in the governing TSO-C127 and TSO-C39C.

This SAE Aerospace Recommended Practice (ARP) is only applicable to 14 CFR Part 25 transport airplane passenger and flight attendant 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. Additionally, it is recommended to use materials that meets the requirements of 14 CFR Part 25 Appendix F, Parts IV and V in applications where not required. Independent furniture installations related to seat installations are outside the scope of this document.

This SAE Aerospace Recommended Practice (ARP) defines acceptable methods for determining the effect of disinfectants application to passenger and crew seating products in transport aircraft. This ARP selected a standard application process for all disinfectants in order to remove one variable from the investigation, which, at the time, was more concerned with the unknown effect of disinfectant chemicals on seat materials. The SAE Aircraft Seat Committee noted that most disinfectant manufacturers have their own application regimens to ensure the effectiveness of their product and that these differ from those defined in the ARP. Consequently, the standard application methodology defined in the ARP is not suitable for qualifying disinfectants, but is rather a standard method to compare the disinfectant’s behavior across a range of seat materials. Acceptance of individual disinfectants for specific application regimens is outside the scope of this ARP.

This Aerospace Recommended Practice (ARP) defines acceptable methods for determining the seat reference point (SRP), and the documentation requirements for that determination, for passenger and crew seats in Transport Aircraft, Civil Rotorcraft, and General Aviation Aircraft.

In addition to those aspects of a passenger seat as comfort and appearance, the passenger seat, whether aft, forward or side facing, is the basic link that supports and ties the occupant to the aircraft structure. It is essential that the support and tie down functions be accomplished in a manner that will provide maximum safety during all normal conditions of flight, emergency flight maneuvers and crash landings, whether on land or water, and that these functions are not compromised to attain the comfort and appearance features.

Seat furnishings are installed around seats and are intended to enhance passenger privacy and comfort. They may have provisions for additional occupants to be seated when the aircraft is in-flight, but would not be occupied during taxi, take-off, and landing (TTL). This Aerospace Standard (AS) establishes the minimum design, performance and qualification requirements for seat furnishings with and without upper attachments (see Figures 1 and 2) to be installed in large transport category airplanes. This standard excludes seat furnishing designs that are directly attached to the seat assembly, for which AS8049 is the applicable standard. Integrated items (desk tops, cabinets, shelves, stowage areas, closeouts, dividers, etc.) connected to seat furnishings shall comply with the requirements of this AS as part of the seat furnishings.

This SAE Aerospace Standard (AS) defines minimum performance standards, qualification requirements, and minimum documentation requirements for passenger and crew seats in civil rotorcraft, transport aircraft, and general aviation aircraft. The goal is to achieve comfort, durability, and occupant protection under normal operational loads and to define test and evaluation criteria to demonstrate occupant protection when a seat/occupant/restraint system is subjected to statically applied ultimate loads and to dynamic impact test conditions set forth in the applicable Federal Regulations 14 CFR Part 23, Part 25, Part 27, or Part 29. This document also provides guidance for design by enumerating certain design goals to enhance comfort, serviceability, and safety. Guidance for test procedures, measurements, equipment, and interpretation of results is presented to promote uniform techniques and to achieve acceptable data.
