TL;DR: An automatically adaptive cockpit side task provides a saturating level of pilot workload and allows the sensitive, orderly, and statistically reliable measurement of a pilot's residual attention as a common metric for navigation and control system assessment.
Abstract: : In 1969, by specifically including 'pilotage error' in the error budget for area navigation system certification, the Federal Aviation Administration legally attached economic premiums and penalties to human as well as equipment performance in man-machine system design. To establish the accuracy of use and freedom from pilot blunders associated with systems employing various configurations of displays and controls requires both simulator and flight experimentation. An automatically adaptive cockpit side task provides a saturating level of pilot workload and allows the sensitive, orderly, and statistically reliable measurement of a pilot's residual attention as a common metric for navigation and control system assessment. A simulation experiment employing this measurement system compared pilot performances as a function of the number of waypoints that could be stored in an airborne area navigation (RNAV) computer (1, 2, 4, or 8) and the type of manual flight control system used (normal flight control versus maneuvering performance control).

TL;DR: Air navigation aids vary widely in both complexity and performance capability and these factors have a significant impact upon communications, data processing, and display, both in the air and on the ground.
Abstract: This paper is designed as a survey document to be used as an overview and introduction to the various concepts and levels of complexity of current and future aids to air navigation. Major emphasis will be placed on identifying those technical and operational characteristics of each system concept and/or mechanization that have a significant impact upon both cockpit and ground-based communications and data processing. A representative bibliography is included to provide the reader the ability to pursue the subject further from an operational as well as a technical viewpoint. The object of this paper is to identify the relationship of air navigation aids to the flow and utilization of information in air navigation and air traffic control (ATC). Air navigation aids vary widely in both complexity and performance capability and these factors have a significant impact upon communications, data processing, and display, both in the air and on the ground.

TL;DR: A radio navigation system for use on the high-seas should be adaptable to a high degree of automation such as in a computerized integrated ship conning system.
Abstract: There are segments of the maritime community that seem to imply increasingly stringent requirements in respect to radio navigation systems. There is at this time no general consensus of users or user groups for the requirements of a radio navigation system for the high seas. A radio navigation system for use on the high-seas should be adaptable to a high degree of automation such as in a computerized integrated ship conning system. When manually operated it should be simple and quick. In all fairness to the commercial user, he should be supplied with useful synopsis of systems he would be asked to consider in the fulfillment of his requirements. Each synopsis should include information on: general description of the system; coverage, accuracy in various parts of the coverage area; reliability and availability of the system; time required to obtain data; form of output data; capability for integration with other systems; operator skill required; direct or indirect cost to the user.
