An area navigation capability can be of considerable benefit to users as well as providers of ground facilities. A.T.C. radar terminal service and area navigation utilizing cockpit pictorial displays are complementary from a total system viewpoint. Pictorial displays, coupled with digital computers capable of storing navigation information, will greatly reduce pilot workload. Optimum usage of A.T.C. radar service and cockpit navigation will provide maximum redundancy at least total cost and reduce controller workload.
Pictorial computer procedures will have many applications of benefit to high density terminal areas, such as (1) departure paths from a satellite airport, (2) descent paths from high altitude to a terminal area, (3) missed approach patterns, (4) approaches to satellite airports, (5) simplified holding procedures, and (6) discrete paths for descent corridors. Procedures are expected to be developed as a result of a full-scale Federal Aviation Administration operational programme for selected en-route and terminal areas permitting use of area navigation facilities, using F.A.A., airline and general aviation aircraft in a live A.T.C. environment.
