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.
In response to a U.S. Air Force Executive Weapon Systems Review (EWSR) Task Group (TG) charter, SAE International Common Launch Acceptability Region (LAR) Approach (CLARA) TG produced an Interface Control Document (ICD). The EWSR recognized the expensive nature of the present multiple-LAR development approaches and sought help from the SAE to standardize and document a new common LAR approach that is less expensive and time consuming. The EWSR TG recommended key characteristics upon which to base the new approach. This Rationale Document describes the thoughts and basis behind the decisions and data generated and documented by the SAE AS-1B5 CLARA Task Group in the creation of the CLARA ICD.
