An Evaluation Trial of the Navigation Accuracy of the L-1011

The accelerated growth of aircraft operations is causing severe congestion problems at major airports throughout the world and adding heavy burdens on Air Traffic Control which result in traffic delays. Area navigation is regarded as a solution to this problem and a means of more efficient and safe utilization of airspace, both en route and in the terminal area. It is important to evaluate the navigation accuracy of RNAV systems in the Japanese airspace before introducing the concept of Area Navigation technique.
