GLIDE PATH ANTENNA SYSTEM IMPROVEMENTS

Abstract

Efforts were made (1) to construct the necessary hardware required to modify and improve the Glide Slope portion of an ILS installation, by utilizing a different antenna system, at a site where the Null-Reference antenna array was noncommissionable and the Sideband-Reference array yielded marginal results; and (2) to demonstrate the improvement realizable at certain types of FAA sites by actually conducting comparison flight tests at a facility where the terrain forward of the glide slope installation resulted in the situation mentioned. These efforts resulted in the following: (1) the M Array made a substantial improvement in the glide slope at McGhee-Tyson Airport, Knoxville, Tenn.; (2) an improvement can be obtained at other FAA sites which are marginal or uncommissionable due to terrain conditions such as exist at McGhee-Tyson Airport; and (3) optimum antenna height and calibration for width monitor should be investigated at the first permanent installation to determine if a location other than the path edge is desirable.
