This report updates and consolidates the economic analyses of three previous FAA/METREK studies related to future domestic air navigation. Subsequent to the writing of one of these reports, which demonstrated the benefits of VORTAC modernization, the Airway Facilities Service (AAF) made significant revisions to both the F/E and O/M cost estimates for VORTAC modernization. The FAA also updated its estimate of distribution of VOR and DME among the general aviation population. This report documents the impact of these changes. There are no significant changes to both LORAN-C and GPS avionics cost estimates at this time. The study shows that there is no cost advantage in replacing the present VOR/DME system unless more stringent needs, such as area navigation, coverage and accuracy become necessary. Based on the estimated avionics costs the results show that the total cumulative costs (discounted at 10%) to the user plus government, for the various alternatives studied from the year 1985-2010, range from $695 million for VOR/DME, and $865 million for LORAN-C, to $970 million for GPS. It is further shown that if either LORAN or GPS ever become the primary air navigation system, then keeping the VOR for general aviation for a lengthy transition period would be economically attractive.
