Glide Path Indicator



ICAO recommends the use of a visual approach slope indicator, especially at night,where one or more of the following conditions exists:

• obstacle clearance, noise abatement or traffic control procedures require a particular slope to be followed;

• the environment of the heliport provides few visual surface cues;

• the characteristics of the helicopter require a stabilized approach. The Glide Slope Indicator is a simple and compact equipment that complies with NATO STANAG rules, usually adopted in the Military land and naval applications, and it is therefore familiar with the majority of the Pilots It mainly consists in a projector emitting a three sectors (amber, green, red) light beam (see specific photometric diagram), that can be set to indicates slope angles between 0° to 30°. Its high efficient design allow a 20km visibility in night operations in Visual Meteorological Conditions . It should be located adjacent to the nominal aiming point and aligned in azimuth with the preferred approach direction.
