1.2.1.3 Glidepath Description
To shape the glide path signal, ground plane reflection from an area in front of the antenna
array is necessary. The specific requirements to the area are given in the antenna handbook.
The glide path site may be located on either side of the runway, but the most reliable operation
will be obtained if the site is selected on terrain least obstructed by taxiways, aircraft holding
aprons, parking ramps, buildings, power lines etc. The site should offer the widest area of
smooth ground with possibilities of levelling without excessive physical or economical effort, if
indeed levelling is deemed necessary.
The glide path antenna system should be located at a distance of 75-200 m from the runway
center line. The distance from the runway threshold is a function of several factors upon which
establishment of the optimum operational conditions depend. These factors are:
