Practical guide for installing obstruction lights on water castles

 

The presence of water towers is a risk for aircraft flying at low altitude. The competent authorities have created rules to signal these obstacles in order to obtain a certain degree of safety. Any object that poses a danger to aircraft flying at low altitudes must be marked with beacons.

The International Civilian Authority (ICAO) legislated in Chapter 6, the rules on the characteristics of beacon lamps and their installation methods.

 

 

Positioning of the beacon lamps Key points, obstruction light selection and installation

 

1. The configuration of the beacon lamps should first take into account the height of the obstacles or buildings, and the total height of the structure in meters shall be calculated from above ground level. <45m low intensity beacon lamps > 46m medium intensity beacon lamps

2. In the case of an object to be light-marked, one or more low- and medium-intensity beacon lamps should be placed above the upper parts of the water tower.

3. For a large object that should be illuminated, obstruction lights must be fitted to indicate the basic contour of the object: the arrangement and quantity should be able to identify obstacles in each azimuth and no part should be covered. of obstacles.

Depending on the diameter of the water tower, the number of obstruction lights required is chosen, so as to mark the upper contour, so that it is visible from any direction, an aircraft is approaching.

 

6 m or less 3 beacon units / per level 

 

6m to 30m 4 Beacon units / per level

 

30 m to 60m 6 Beacon units / per level

 

more than 60m 8 beacon units / per level
