Curves that may be useful for establishing preliminary allocation plans were prepared for a fixed combination of antenna heights and assume propagation over a smooth earth. They make no allowance for a wide range of propagation path profiles or atmospheric conditions that may be encountered over particular paths. A method for computing preliminary reference values of transmission loss is described. It is based on a simple model, may readily be programmed, and is especially useful when little is known of the details of terrain.

Desired to undesired signal ratio predictions for the VHF Omnirange (VOR) and Instrument Landing System (ILS) air navigation aids are presented. The parameters involved in these systems are given first. Propagation mechanisms applicable to VHF/UHF and the calculation of transmission loss and its variability are then discussed, and, third, the statistical nature of the desired-to-undesired signal ratio predictions is explained. The results of the study, presented in graphical form, supplement those given by the authors in an earlier ESSA Technical Report on the same subject. In addition to extending the range of variables previously considered, this report considers the glide slope portion of the ILS.
