Helicopter Engine-Rotor System CompatibilityARP704A (Current)7/2/2026
This SAE Aerospace Recommended Practice (ARP) recommends a methodology to be used for the design, analysis and test evaluation of modern helicopter gas turbine propulsion system stability and transient response characteristics. This methodology utilizes the computational power of modern digital computers to more thoroughly analyze, simulate and bench-test the helicopter engine/rotor system speed control loop over the flight envelope. This up-front work results in significantly less effort expended during flight test and delivers a more effective system into service. The methodology presented herein is recommended for modern digital electronic propulsion control systems and also for traditional analog and hydromechanical systems.

658 Internet Protocol Suite (IPS) for Aeronautical Safety Services - Roadmap DocumentARINC658 (Current)12/18/2017
ARINC 658 was prepared to recognize the expanding role of data communication technology and the evolutionary path forward starting from ACARS protocols, to ATN/OSI protocols, and eventually ATN/IPS protocols using highly secure networks. The ATN/IPS network will be implemented onboard an aircraft and in the ground infrastructure to support safety services, including Air Traffic Services (ATS) and Aeronautical Operational Control (AOC). As such it provides a so-called "roadmap" for the development of the aviation standards for ATN/IPS services.

446 Guidance for Flight Training Device Documentation Structure, Content, and MaintenanceARINC446 (Current)1/1/2016
The intent of this standard is to provide guidance so the documentation provided with the Flight Simulation Training Device (FSTD) reflects and describes the delivered FSTD, including the description and definition of third party equipment and content. In the context of documentation guidance found in this report, the term FSTD is meant to include all levels of flight simulation devices. The documentation described herein is required for the operator to independently support the FSTD in the maintenance, operation, and update of the device throughout the lifetime of the device. This report describes a superset of a possible range of documentation involved in the initial delivery or an update of a FSTD. The deliverable documentation set for a particular FSTD may vary depending on the level of device (e.g., flat panel trainer versus a full flight simulator) as well as issues related to intellectual property, export compliance, technical requirements, and/or contractual agreements.

Dynamic Modeling of Aerospace Systems (DyMAS)ARP6538 (Current)5/24/2018
The objective of this document is to provide a recommended practice for the development of aerospace EPS dynamic models so that models developed by different companies/industries/governments/etc. will have a basic level of compatibility and interconnectivity. This will be crucial as the aerospace industry looks to solve the challenges of the 21st century through integrated vehicle optimization. This document focuses on model interfaces and their interconnection. Other than these boundary characteristics, this document does not attempt to describe or regulate the inner workings of individual component models. AIR6326 defines the four-level paradigm for aircraft EPS MSAT studies. Of the four levels, Device Physical, Behavioral, Functional, and Architectural, only the first three are dynamic models. Further, the Device Physical level is too detailed and not intended to be interconnected to other EPS models. Thus, only the middle two levels – Behavioral and Functional – will be covered by
