FEDERAL AUTOMATED WEATHER OBSERVING SYSTEM (AWOS), CURRENT AND FUTURE ATTRIBUTES

Todd C. Harder, TRW Inc, Washington, DC; and J. Dunlap

The installation contract for the Federal AWOS (Automated Weather Observing System) program was let in 1988 to provide aviation weather observations in the National Airspace System (NAS). The 198 Federal AWOSs procured and commissioned contain early 1980's hardware and technology. The systems currently function as designed, but maintenance and other considerations are pertinent in order for the system to remain functional in the NAS for the next 10+ years. The FAA has analyzed the Federal AWOS for compliance with user needs and has investigated factors to reduce costs associated with operations, maintenance, and enhancements. This information assisted in identifying strategies to be implemented by the FAA within the next year. Total replacement is an option, but data indicates other alternatives are viable and more cost-effective. The alternatives to be investigated in more detail are: extension of system life and reduction of maintenance costs by incorporating state-of-the-art sensors/equipment, increasing processor capability, and adding additional sensors. The alternatives may be a variety of combinations depending on criteria currently under development. These factors will be used by the FAA to assess how to continue the reporting of weather information via the Federal AWOS program
