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.

ARINC 834A-1 Internet Protocol Based Aircraft Data Interface Function (ADIF)ARINC834A-1 (Current)7/2/2026
This standard defines the services, the transport layers, and the suggested security mechanisms to enable communication between aircraft systems and an Electronic Flight Bag (EFB). Herein is the definition of a set of protocols and services for the exchange of aircraft avionics data across aircraft networks. The purpose is to define a common set of services to be used to access specific avionics data that will enhance EFB applications. Supplement 1 introduces bi-directional communication between the EFB and FMS. It also enables mutual Transport Layer Security, incorporating client authentication.

Liquid Leak Tightness Evaluation Methodology for EV Battery Packs Informational ReportJ3277_202404 (Current)4/23/2024
This technical information report (IR) presents a methodology to evaluate battery pack liquid leak tightness attributes to be used in a production line to satisfy the functional requirement for IPX7, water ingress requirement, and no sustainable coolant leakage for coolant circuits. The Equivalent Channel Method is used as a suggested production leak tightness requirement for a given battery pack design that will correlate and assure that the battery pack meets or exceeds its functional requirement. Obtaining the specific geometry of the Equivalent Channel (EC) for a given battery pack is done analytically and empirically in consideration of the product design limitations. This document is a precursor to J3277-1, which will present the practices to qualify that product leak tightness is equal or better than the maximum allowed EC for that product using applicable and commercially available leak test technologies. This document may be applied to EV and HEV battery packs as tested during

This SAE Recommended Practice is part of the SAE J2534-2/X_0500 set of documents that extends the SAE J2534-1_0500 API (version 05.00) specification, and defines how to implement ethernet within the SAE J2534 API framework. This document details only the changes from SAE J2534-1_0500 and items not specifically detailed in this document are assumed to have not changed. An SAE J2534-2/13_0500 interface shall be compliant to the ethernet feature only when all the required functionality in this SAE Recommended Practice is implemented. Any functionality not required for compliance will be specifically marked as “optional” in this document. This document must be used in conjunction with the SAE J2534-2/BA_0500 and SAE J2534-2/RE_0500 documents.

Aerospace Operator Self-Verification ProgramsARP9062A (Current)11/14/2006
Operator Self-Verification can apply to a variety of processes. The primary focus is on traditional manufacturing operations, but applications can be made wherever traditional inspection methods are employed. The practices recommended in this document are intended to identify the basic elements for structuring Operator Self-Verification programs within the aerospace industry; applicable to producers of commercial and military aircraft and weapons platforms, space vehicles, and all related hardware, software, electronics, engines and composite components. Operator Self-Verification programs are applied to improve overall efficiency and product quality to processes considered mature, as judged by the organization. Operator Self-Verification programs are not stand-alone processes, but augment existing quality management system standard requirements. The identified program elements are for voluntary organizational application, and are not intended for contractual flow-down unless otherwise
