The Display and Use of Navigational Intelligence

For future navigation systems the major problems in development will be as much concerned with the presentation and use of data as with its provision. The relationship between a stated operational requirement and the means developed to meet it are discussed on this basis. The nature of different types of navigational intelligence are considered, and a distinction is drawn between control and monitoring functions. The navigational task is analyzed, and different types of associated displays are examined. Safety considerations call for a degree of redundancy in a complete system, and the importance of avoiding dependence on a single navigational technique is emphasized.
