Abstract : Laboratory and flight tests of an area navigation system designated as the VOR/DME Onbutrac 1A were performed at the National Aviation Facilities Experimental Center (NAFEC), Atlantic City, New Jersey, and in the air traffic control environment. The flight tests in a Federal Aviation Administration Gulfstream aircraft (N-376) were divided into operational tests between Washington, D. C., and Atlanta, Georgia, and engineering tests between Atlantic City, New Jersey, and Washington, D. C. Subjective and engineering data were obtained. Based on the evaluation of the data collected, it was determined that: Enroute area navigation accuracies were within present airway widths; Flight technical error was the major contributing factor to the total navigation error; The total electronics navigation error, which included the errot contribution of the Omnitrac, was small in comparison to the flight technical and total navigation errors; Navigation with the Omnitrac was preferred by the subject pilots over conventional navigation due to the increased operational options associated with area navigation; Control of an aircraft equipped with area navigation equipment minimized the need for radar vectoring, permitted direct and parallel routings, and reduced the communication workload.
