TL;DR: In this paper, a simulation study analyzed selected controller workload and system performance measures for two route configurations representing two time frames and various percentage mixes of area navigation (RNAV) and non-RNAV operations, referred to in this report as participation levels.
Abstract: : The simulation study analyzed selected controller workload and system performance measures for two route configurations representing two time frames and various percentage mixes of area navigation (RNAV) and non-RNAV operations, referred to in this report as participation levels. Results indicated that controllers could use RNAV maneuvers in the control of traffic in lieu of radar vector techniques and that controller workload decreased as the RNAV participation level increased. Controller acceptance of RNAV principles and techniques in terminal ATC increased as familiarity and experience with the various RNAV functions were gained. Subjective results pointed out that in order that RNAV be an effective tool within the terminal air traffic system, adequate training and a thorough familiarization with RNAV procedures, capabilities, and limitations would be a requirement for both controllers and pilots.

TL;DR: In this article, the authors compared the expected cost and performance of Differential Omega with that of Loran-C and VORTAC for general aviation area navigation and found that the latter system offers the highest performance with respect to accuracy.
Abstract: this paper reports on a study which compared the expected cost and performance of Differential Omega with that of Loran-C and VORTAC for general aviation area navigation. Analysis is directed toward a comparison of the systems with respect to specified performance parameters and the cost-effectiveness of each system in relation to the specifications. Loran-C offers the highest performance with respect to accuracy. Differential Omega requires the least expenditure. It was found cost ineffective to attempt to obtain complete coverage by expanding the existing VORTAC system.

TL;DR: The method of approach in this analysis is to use a coordinated concept of data collection and experiment design in order to maintain a strict discipline concerning commonality of acquired data such that from one experiment complements and cross correlates with data from other FTE experiments.
Abstract: : The primary objective of this effort is to determine whether a one mile flight technical error is achievable in enroute and terminal area operations using various types of airborne RNAV equipment. Flight technical error (FTE) is evaluated using both controlled cockpit simulator and flight test experiments, as well as operational flight test experiments in the existing airspace environment. Due to the scope and magnitude of this particular component of the area navigation error budget, the method of approach in this analysis is to use a coordinated concept of data collection and experiment design in order to maintain a strict discipline concerning commonality of acquired data such that from one experiment complements and cross correlates with data from other FTE experiments. One primary element of the coordinated experimental investigations is to determine RNAV procedural and operational requirements and capabilities. FTE magnitude and its impact on airspace planning, RNAV system manufacturers, RNAV users and air traffic controllers is analyzed in the main text taking into account the following: RNAV equipment and display factors, FTE performance in turns, performance in parallel offset, delay fan and direct to maneuvers, effects of workload and airspace utilization. RNAV error budget element combination is also analyzed. The currently used RSS technique is compared to a modified version of this computation which is more accurate in predicting the total system cross track error. Appendices A,B, C and D present detailed analyses of the controlled cockpit simulator tests, airline type RNAV system tests and operational flight tests using general aviation quality RNAV systems.
