A Comparison of Air Radionavigation Systems (For Helicopters in Off-Shore Areas).

摘要

This paper examines the technical potential of ten navigation systems that may meet specific IFR en route navigation requirements for helicopters operating in off-shore areas. Technical factors considered essential for navigation are: (1) operational range, (2) operational altitude, (3) accuracy, and (4) reliability. Not addressed in this paper are such operational factors as pilot workload, number of way points, type of display, etc. Estimated user equipment cost will be included because of its importance in system selection.
