The information presented in this AIR is intended to provide designers of armed unmanned systems with guidelines that may be applied to ensure safe integration and operation of weapons on unmanned platforms. The guidelines have been developed from experiences gained in the design and operation of weapons on manned aircraft that have been accepted by relevant safety authorities in the USA and Europe and proven effective over many years. Whilst the guidelines have been developed from experience with aircraft operations, the concepts are considered equally applicable to non-aircraft systems, such as those used on the surface or undersea environments.

The Loran-C Radionavigation System, managed by the U.S. Coast Guard, is the federally provided radionavigation system for civil marine use in the U.S. coastal waters. It is also designated by the Federal Aviation Administration (FAA) as a supplementary system in the National Airspace System (NAS). This system provides accurate radionavigation and timing services to users in the United States of America and Canada. Loran-C is also being used and developed by several other countries in Europe and Asia. Estimates of Loran-C system accuracy must take into consideration the transmitted signal, signal propagation, signal reception, interference or errors from outside sources such as natural and man-made electromagnetic noise, skywave contamination, geometric dilution of precision, other Loran-C signals, communication information superimposed on the navigation signal, and coordinate conversion.

This ARP provides guidelines for improving the Failure Mode and Effect Analysis process, including alternative or additional methods, for flight critical actuation equipment electronics and software.
This SAE Aerospace Standard (AS) contains requirements for a digital time division command/response multiplex data bus, for use in systems integration, that is functionally equivalent to MIL-STD-1553B with Notice 2. Even with the use of this document, differences may exist between multiplex data buses in different system applications due to particular application requirements and the options allowed in this document. The system designer must recognize this fact and design the multiplex bus controller (BC) hardware and software to accommodate such differences. These designer selected options must exist to allow the necessary flexibility in the design of specific multiplex systems in order to provide for the control mechanism, architectural redundancy, degradation concept, and traffic patterns peculiar to the specific application requirements.
The information presented in this AIR is intended to provide information about current remote identification methods and practical considerations for remotely identifying UAS. Depending on rigor and adherence requirements, Aerospace Standard (AS) and Aerospace Recommended Practice (ARP) documents may be developed. For example, ARPs may provide methods to remotely identify UAS using existing hardware technologies typically available to most consumers. ARPs may also specify the information exchange and message format between unmanned aerial systems and remote interrogation instruments. An AS, however, may highlight the wireless frequency band, message type, message encoding bits, and message contents.

(1) The Behavior Annex document provides a standard sublanguage extension to allow behavior specifications to be attached to AADL components. The aim of the Behavior Annex is to refine the implicit behavior specifications that are specified by the core of the language. The Behavior Annex targets the following goals: • Describe the internal behavior of component implementations as a state transition system with guards and actions. However, the aim is not to replace software programming languages or to express complex subprogram computations. • Extend the default run-time execution semantics that is specified by the core of the standard, such as thread dispatch protocols. • Provide more precise subprogram calls synchronization protocols for client-server architectures.

To fulfill this objective, the FAS must attract the attention of the crew, must state with clarity the nature and location of the problem, and must be highly reliable and thoroughly responsive to the operational requirements and environment. Wherever possible, it should provide guidance as to the corrective action.
