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.

This document describes a practical system for a user to determine observer-to-aircraft distances. These observer-toaircraft distances can be either closest point of approach (CPA) distances during field measurements or overhead distances during acoustic certification tests. The system uses a digital camera to record an image of the subject aircraft. A method of using commercial software to obtain the distance from such an image is presented. Potential issues which may affect accuracy are discussed.

This document describes a process that may be used to perform the ongoing safety assessment for (1) GAR aircraft and components (hereafter, aircraft), and (2) commercial operators of GAR aircraft. The process described herein is intended to support an overall safety management program. It is to help a company establish and meet its own internal standards. The process described herein identifies a systematic means, but not the only means, to assess continuing airworthiness. Ongoing safety management is an activity dedicated to assuring that risk is identified and properly eliminated or controlled. The safety management process includes both safety assessment and economic decision-making. While economic decision-making (factors related to scheduling, parts, and cost) is an integral part of the safety management process, this document addresses only the Ongoing Safety Assessment Process.

This document describes a method to calculate noise level adjustments at locations behind an airplane (described by an angular offset or directivity) at the start of takeoff roll (SOTR). This method is derived from empirical data from jet aircraft (circa 2004), most of which are configured with wing-mounted engines with high by-pass ratios (Lau, et al., 2012).

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.

ARP4912C
This SAE Aerospace Recommended Practice (ARP) provides recommendations on cavity design, the installation of elastomer type spare seals in these cavities, and information surrounding elastomer material properties after contact with typical shock absorber hydraulic fluid(s) or grease. This ARP is primarily concerned with the use of spare seals on shock absorbers where only a single dynamic seal is fitted and in contact with the slider/shock absorber piston at any one time. These shock absorbers typically have a spare (dynamic) seal gland located on the outer diameter of the lower seal carrier. This spare seal gland is intended to house a spare elastomer contact seal. Split Polytetrafluoroethylene (PTFE) backup rings can also be installed in the spare seal cavity. During operation, if the fitted dynamic shock absorber standard seal begins to fail/leak, then the aircraft can be jacked up, allowing the lower gland nut of the shock absorber to be dropped down.

ARP1420C
The turbine-engine inlet flow distortion methodology addressed in this document applies only to the effects of inlet total-pressure distortion. Practices employed to quantify these effects continue to develop and, therefore, periodic updates are anticipated. The effects of other forms of distortion on flow stability and performance, and of any distortion on aeroelastic stability are not addressed. The guidelines can be used as necessary to create a development method to minimize the risk of inlet/engine compatibility problems. The degree to which guidelines for descriptor use, assessment techniques, and testing outlined in this document are applied to a specific program should be consistent with the expected severity of the compatibility problem.

The aerospace industry is facing some of its biggest challenges to date. Chief among these are range and endurance limitations, restricted flight envelopes caused by thermal constraints, increasing power demands, and power compatibility issues. Unlike past challenges, these are too complex to solve at just the component level, and a subsystem and/or air vehicle level analysis is necessary. An important tool utilized by aerospace community for this is modeling, simulation, analysis, and testing (MSAT). Unfortunately, there are as many modeling methods as there are model users. Thus, a set of modeling standards and guidelines is necessary in order to facilitate the interconnection and compatibility of electric power system models across industry. This document, the Dynamic Modeling and Simulation (DyMAS) Aerospace Recommended Practice, provides this.

This document provides a review of published methods that have been used to provide estimates of the levels of distortion and/or the concomitant loss of stability pressure ratio that can occur when the recommended full complement of aerodynamic interface plane high-response instrumentation is not used when obtaining inlet data. The methods have been categorized based on the underlying mathematical representation of the aerophysics. Further, the use of maximum value statistics, which has been used to further improve the results where short-duration time records have been employed, is discussed.

This SAE Aerospace Recommended Practice (ARP) provides guidance and interpretation on how to apply the objectives and activities in ARP4754A, “Guidelines for Development of Civil Aircraft and Systems”, to propulsion systems with electronic engine control. As the ARP4754A was developed and written more generally at the aircraft level, guidance will be provided to allocate ARP4754A objectives and activities to each side of the aircraft/engine interface. Using this guidance, certification applicants (aircraft and engine manufacturers) will be able to make proposals to coordinate their activities with their respective authority based on this allocation with the objective of distributing efficiently the compliance demonstration efforts between engine and aircraft certification and of avoiding unnecessary duplication of work.

AIR6387
The development of future more-and full-electric aircraft concepts has significantly impacted aircraft electric power system (EPS) design. Finalizing the EPS architectures involves extensive modeling and simulation activities to ensure the required characteristics of the entire EPS prior to the physical implementation. Hence, the development of accurate, effective and computational time-saving simulation models is of great importance. Correspondingly, there is a need to establish an EPS-specific modeling and simulations common framework to ensure effective and accurate solutions to the problems addressed. The document continues a series of AE-7M documents specific for aircraft electrical systems aiming to establish such a framework (the series has started with AIR 6326 "Aircraft Electrical Power Systems. Modeling and Simulation. Definitions" issued in August, 2015).
