Clarify the role of the human considerations in Functional Hazard Assessments by identifying the sufficient input information regarding those considerations from the development process, how failure conditions may use that information, and what information the safety assessment process provides to other processes, particularly Human Factors, to assure those aspects of failure conditions are valid.

This AIR would examine the applicability of ARP 4754 and ARP 4761 to UAS and would identify the shortcomings in both recommended practices with regards to the specific technical aspects needed for UAS development.

This Aerospace Informational Report (AIR) provides guidance on using environmental, electrochemical, and electrical resistance measurements to monitor environment spectra and corrosivity of service environments, focusing on parameters of interest, existing measurement platforms, deployment requirements, and data processing techniques. The sensors and monitoring systems provide discrete time-based records of 1) environmental parameters such as temperature, humidity, and contaminants; 2) measures of alloy corrosion in the sensor; and 3) protective coating performance in the sensor. These systems provide measurements of environmental parameters, sensor material corrosion rate, and sensor coating condition for use in assessing the risk of atmospheric corrosion of the structure.

This document provides information on current practices for testing air data probes to 14 CFR Part 33 Appendix D ice crystal and mixed phase icing conditions. This AIR is primarily concerned with techniques for measuring the flow and icing environment in the test facility. While the focus of this report is the testing of air data probes, techniques described may be applicable to Appendix D tests of other aerospace equipment as well.

This document describes the approaches taken to define safe-life limits for the management of fatigue in landing gear structures, and the substantiation of those limits through full-scale fatigue testing. The safe-life scatter factors considered in a range of military and civil regulatory standards are also reviewed.

A review of icing materials that would be educational to a designer of a UAV ice protection system is provided. Additionally, the differences between unmanned and manned ice protection systems are explored along with a discussion on how these differences can be addressed.

The scope of the test method is to provide stakeholders including fluid manufacturers, brake manufacturers, aircraft constructors, aircraft operators and airworthiness authorities with a relative assessment of the effect of deicing chemicals on carbon oxidation. This test is designed to assess the relative effects of runway deicing chemicals by measuring mass change of contaminated and bare carbon samples tested under the same conditions.

This document was requested by the FAA to provide a technical update of TSO-C26d to address Electric Brake Actuation, standardize with TSO-C135a and address any remaining concerns with the current technical requirements in AIR5381.

Aircraft-mounted Closed Circuit Refueling receiver adapter – Definition of standard interface dimensions for adapter which interfaces with MIL-PRF-52747F Nozzle.

This SAE Aerospace Standard defines a bulkhead coupling (with different fitting end styles), which is used in bulkhead cone connection fittings installed in high pressure (3000 psi) oxygen systems for the purpose of mating to applicable oxygen equipment. Dimensions developed from AND10089, Detail Specification Sheet for Fitting End, Design Standard, For Cone Connection.

This SAE Aerospace Standard (AS) prescribes the Minimum Performance Standards (MPS) for environmental conditions that wheel, brake, and wheel and brake assemblies to be used on aircraft certificated under 14 CFR Parts 23, 25, 27, and 29. The environmental requirements in this document shall be used in conjunction with other MPS defined in Technical Standard Orders for the applicable equipment.

This Aerospace Standard will provide the basis for a certification approach and contain the methods or criteria for verification of performance required for Oxygen Dispensing Units to be used by Cabin Crew up to 25,000 ft. cabin altitude.

This SAE Aerospace Standard (AS) establishes the requirements for bulkhead-on-side-tee cone connection fittings, for use in aircraft oxygen systems at nominal operating pressures up to and including 3000 psi.
