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. This document does not attempt to define or describe a comprehensive safety program for unmanned systems. System Safety is a system characteristic and a non-functional requirement. It has to be addressed at each level of system design, system integration and during each phase of system operation.

This document specifies the CLARA interfaces of the CLAR Truth Data Generator as shown in Figure 1. The solid bold arrows are defined in Table 1 and Table 2. The dashed arrows from the CLAR Coefficient Generator and Truth Database to the CLAR Data Space Generator indicate a feedback loop and are defined in the CLAR Data Space Generator ICD (Reference 1). The dashed arrow from the Truth Database to the CLAR Coefficient Generator is defined in the CLAR Coefficient Generator ICD (Reference 2). The objective for the CLAR Truth Data Generator is to produce impact data sets to be used in the CLAR Coefficient Generator first to score and form LAR boundaries, and then to generate coefficients. A model of the weapon system that predicts weapon delivery performance to a predefined accuracy is to be used for this purpose. The model can be the Six-Degree-Of-Freedom (6DOF) equations of motion or another mathematical representation that meets the objective for the weapon system LAR.

This document was developed by the SAE AS-1B5 CLARA Task Group to explain and document background information and decisions with associated rationale made in development of the CLARA Interface Control Document (ICD), AIR5682. This rationale document is published separately to preserve information that is not required or provided in the ICD but may be important to users.

CLARA identifies four functions: Data Space Generator, Truth Data Generator, Coefficient Generator, and Reconstructor. Together these four functions standardize the solution to the LAR problem. This ICD defines the logical interfaces of the four functions.

This SAE Aerospace Information Report (AIR) defines a Generic Aircraft-Store Interface Framework (GASIF). This is a common framework for modeling and specifying aircraft-store logical interfaces. GASIF complies with the OSI Basic Reference Model (ITU-T Rec. X.200 | ISO/IEC 7498-1) in that it describes operations and mechanisms which are assignable to layers as specified in the OSI Basic Reference Model. This AIR provides a mapping of the Interface Standard for Aircraft-store Electrical Interconnection System (AEIS), MIL-STD-1760, in Appendix C.
