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.

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).

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 Federal Regulations §14 CFR Part 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). A methodology to evaluate the degree of correlation between a seat model and dynamic impact tests is recommended. This ARP also provides testing and modeling best practices specific to support the implementation of analytical models of aircraft seat systems. Supporting information within this document includes procedures for the quantitative comparison of test and simulation results, as well as test reports for data generated to support the development of v-ATDs and a sample v-ATD calibration report.

J2969_201701
This SAE Recommended Practice provides guidelines for procedures and practices used to obtain and record measurements and to analyze the results of the critical speed method. It is for use at accident sites using manual or electronic measurements. The method allows for many unique factors and the recommended procedure will permit a consistent use of the method in order to reduce errors and uncertainty in the results. The results from the critical speed formula should always, when possible, be compared to other accident reconstruction methodologies. When different accident reconstruction methods are used, the uncertainty of each method should be analyzed and presented.

An effective GSS is vital to the successful implementation of an EMS and is a fundamental part of the total monitoring system design, including asset management. Unlike the on-board part of the EMS which principally uses real time data to indicate when engine maintenance is required, a GSS can offer much greater processing power to comprehensively analyze and manipulate EMS data for both maintenance and logistics purposes. This document reviews the main EMS functions and discusses the operating requirements used to determine the basis design of a GSS, including the interfaces with other maintenance or logistic systems. A brief discussion is also included on some of the more recent advances in GSS technology that have been specifically developed to provide more effective diagnostic capabilities for gas turbine engines.

The objective of any organization, as part of continual improvement, is to reduce the number of issues (i.e., undesirable conditions, defects, failures) and to minimize their impact on quality, delivery performance, and cost. This includes having processes in place to detect and eradicate significant and recurrent issues, which implies having well identified problems, a common understanding of their impact and associated root causes, and having defined and implemented adequate actions so that these problems, including similar issues will not happen again.

ARP7998
This is a recommended practice for an interface to supplier simulations that utilize traditional interprocess communication (IPC) methods of shared memory and semaphore communications. These IPC methods are fairly standard practice in the computer science world, that allow for communication by separate processes running on a computer without any common runtime requirements of each process being run. So 32bit applications can talk with 64 bit applications as well as any other compiler or runtime dependency being needed by the calling program to interface with the called system. This also allows the calling program and the called program to be run on separate CPUs to allow parallel execution of the called program as well as multiple instances of the called program to execute all on separate processors.
