Procedure to Evaluate Changes to the FM Broadcasting Table of Assignments to Determine if Interference to Aeronautical Radio Facilities Could Result.
Abstract
For several years the FAA has been receiving complaints of interference to ILS Localizer facilities in the 108 - 112 MHz band, VOR facilities in the 108 - 118 MHz band, and ATC communication facilities in the 118 - 136 MHz band from FM broadcasting stations in the 88 - 108 MHz bands. In 1978, the FAA published a report documenting a test program performed by the National Aviation Facilities Experimental Center (NAFEC) that investigated the problem of FM interference to avionic receivers. At the request of the FAA, the Radio Technical Commission for Aeronautics established Special Committee, SC-141, to study the problem and recommend methods to reduce the potential for interference to avionic receivers. One of RTCA's recommendations was that changes to the Table of FLM Assignments administered by the FCC should be evaluated during the rulemaking process necessary to make such changes, to determine whether interference to aeronautical radio facilities could result. The purpose of this report is to describe a procedure for evaluating changes to the Table of FM Assignments using methods described in the NAFEC report. (Author)
