Abstract : Flight tests were conducted to determine the feasibility of a VORTAC Identification Light. A standard 300-mm 'V' coded beacon, a modified 300-mm 'V' coded beacon and condenser-discharge lights were tested independently to determine the maximum range, under VFR, that positive identification of the VORTAC facility could be obtained. It was concluded that a modified 300-mm 'V' coded beacon or strobeacons mounted on the VORTAC counterpoise, or a standard 300-mm 'V' coded beacon or strobeacons mounted below the 12-foot counterpoise level and 30 feet from the counterpoise edge, provided excellent nighttime identification of the facility. Recommendations were made for additional field tests to determine the actual value of the VORTAC Identification Light to the airways navigation system, the cost to install a complete system at desired VOR facilities, the interference with aircraft and highway traffic, and the nuisance factor to inhabitants near VORTAC facilities.
