DESIGN AND DEVELOPMENT OF THE MODULAR MONITOR SYSTEM INDICATORS.
BENDIX CORP UTICA N Y
The design and development was continued of a modular system to be used by airport Flight Service Stations for monitoring NAVAID equipment. The design objective has been to create equip ment which can readily be adapted to the needs and growth of any Flight Service Station without waste of parts or space. During the design phase of the project, the contractor made studies of existing monitoring equipment and external wiring configurations. The modular design ap proach has been based upon separation of the functions common to all navigational facilities and the repetitive functions necessary for monitoring and control of each site. The repe titive functions are packaged into plug-in modules, each module representing one monitored equipment at a site. Reductions in equipment size were made possible by the introduction of smaller switch-indicators and semiconductor devices powered by a low voltage power suply. All components have been evaluated for perform ance and maintenance-free operation, and the final product thoroughly tested. Author
