Standardization Potential Across Navigation Systems (SPANS).
Abstract
The objective of the SPANS effort is to assess the potential for standardization across avionic navigation systems by identifying standard hardware and software configurations that minimize life-cycle costs while satisfying Air Force operational requirements. The primary output of the effort is a computerized Standardization Evaluation Program (STEP) that quantifies the impact of standardization in those areas of avionics (such as navigation) defined by the program data base. The methodology uses a life-cycle cost model in an iterative manner over a number of aircraft and their associated mission profiles. The life cycle cost model is sensitive to the cost benefits, obtained by widespread use of standard equipment across several aircraft, through cost learning and reliability improvement functions. The SPANS data base consists of three files, including aircraft/mission data, navigation subsystem data and standard cost factors data, that provide the inputs necessary for operation of the STEP program.
