Cost/Benefit Analysis of Televised Radar for General Aviation

J. E. Erickson

An economic evaluation of the costs and potential benefits of broadcasting radar information to general aviation aircraft via TV relay was performed. Benefits were equated to costs of general aviation accidents that might be prevented by broadcasting weather data, area route information or positions of other aircraft. Over 90 percent of general aviation accidents which might be prevented by the use of TV radar indicate weather as the primary benefit area. Therefore it was determined that the most promising area for improvement is in properly presenting weather data. It was determined that benefits of TV radar would exceed costs if at least 50 percent of all general aviation aircraft installed equipment and also that at least 50 percent of general aviation accident costs would be eliminated as a result. However, due to the probability of too few participating general aviation aircraft, the study concludes that no justification exists for pursuing the TV radar concept further at this time. Future improvements in radar, transmission capability, frequency availability and availability of suitable equipment for general aviation aircraft may indicate a need for further reassessment at that time.
