Abstract: This report supplements information previously developed by the authors on interference predictions for VHF/UHF air navigation aids, Included are (a) radiation patterns needed to adapt curves previously developed for the Instrument Landing System (ILS) Localizer and Tactical Air Navigation (TACAN) to new equipment types, (b) comparisons of the propa­gation models used for predictions made from 1962 to the present, (c) propagation information in a different form, i. e., attenuation greater than free space for Distance Measuring Equipment (DME), TACAN and VHF Omnirange (VOR), (d) DME, TACAN and VOR service volume without interference curves for equipment configurations not previously considered, and (e) an errata list for earlier ESSA Technical Reports.

Keywords: interference; propagation; transmission loss; DME; Instrument Landing System (ILS); navigation aids; Tactical Air Navigation (TACAN); VHF Omnirange (VOR)
