Abstract : A low cost system called VORLOC was designed to be used in a manner similar to a standard localizer but operates on VOR frequencies with the standard VOR receiver and instrumentation. The equipment was subjected to severe siting conditions to examine the degree to which course quality would be derogated. Jamestown, New York was selected as a typical small airport with reasonably difficult terrain features. The results of the tests performed at Jamestown were comparable to those obtained at NAFEC. The course line had course path bend amplitude of 0.46 degrees on a 95% probability basis with extremes of 0.23 and 0.90 degrees. Both front and back courses had a range of more than 25 miles at an altitude of 1,500 feet. The characteristics of the VOR TO-FROM Indicator reversed sensing outside plus or minus 30 degrees of arc (approximately) from the on-course line were observed; however, the operational significance of this flag behavior was not established.
