Flight tests were conducted at the National Aviation Facilities Experimental Center NAFEC using an Aeronautical Radio Incorporated ARINC Characteristic 582-4, Mark 2 Air Transport Area Navigation System to investigate area navigation RNAV system accuracies and resultant airspace requirements with emphasis being given to the terminal area. The system was operated in various navigational configurations including dual very high frequency omni-directional radio rangedistance measuring equipment VORDME, single VORDME, and dual DME. Statistical data are presented for the various error components making up the RNAV total system error. Various operational capabilities were also investigated and graphical data are presented for parallel offsets, paralleling in turns, and turn anticipation. The most accurate modes were dual DME and dual VORDME with single VORDME being the least accurate. The feasibility of a Flight Technical Error FTE of less than or - 1.0 nmi in the terminal area was also demonstrated. Author
