General

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 Title 14, Code of Federal Regulations (14 CFR) parts 23, 25, 27, or 29 (as applicable to the seat type, see Table 1).

Guidance for test procedures, measurements, equipment, and interpretation of results is also presented to promote uniform techniques and to achieve acceptable data.

While this document addresses system performance, responsibility for the seating system is divided between the seat supplier and the installation applicant. The seat supplier's responsibility consists of meeting all the seat system performance requirements and obtaining and supplying to the installation applicant all the data prescribed by this document. The installation applicant has the ultimate system responsibility in assuring that all requirements for safe seat installation have been met.

Applicability

This document addresses the performance criteria for forward and rearward facing seat systems (0 degrees to 18 degrees relative to the aircraft longitudinal axis) requiring static and dynamic testing to be used in civil rotorcraft, transport aircraft, and general aviation aircraft. For Type A-T oblique facing passenger seats greater than 18 degrees and no greater than 45 degrees relative to the aircraft longitudinal axis, additional performance criteria are found in AS6316. For side facing seats, additional performance criteria are found in AS8049/1. Seat systems greater than 45 degrees and less than 80 degrees are not addressed in this document.

Seat Types

This document covers all passenger and crew seats for use in aircraft type-certificated in the following categories shown in Table 1:

Units

In this document, U.S. customary units (in-pound) and International System of Units (SI) are provided. In all cases, the in-pound units take precedence and the SI (metric) units provided are approximate and conservative conversions. Those who routinely use SI units in practice may make the conversions more precise.
