The Relevance Of Obstruction Lighting

By Cherry Mercer


Obstruction lighting is used for warning pilots in case of danger. There are two colors: red and white. A system must have a backup method, because it must function at any time, even when there is a power failure. There are situations in which lights can be hard noticing, such as in bad weather conditions. There are special markings that will help pilots in case of low visibility.

White and red beacons have a main purpose: they are meant to protect pilots from accidents. Usually, the lights are installed on high terrain, on various buildings and towers. The beacons must be placed in such a manner to make them visible in every direction. Nowadays, the technology used for the devices is LED, as it is durable and cost effective. More types of indicators have to be used for offering better visibility if night goggles are used.

In some constructions, various types of markings can ensure a visibility improvement. In order to define the shape of a building, multiple beacons may be positioned on its edges. The structure may be barely seen, but the lights can reveal it. LED devices may not be very bright during daytime. However, the use of additional markings, which are more suitable for daylight, can be helpful.

Among other navigational markings, painted stripes are more common. Aviation dangers are noted on charts. The markings can provide additional warnings in case pilots go off course. Extra safety can be obtained if the indicators are clear and precise. The warning lamps have a standard, which is given by ICAO, or the International Civil Aviation Association.

Manufacturer companies of obstruction lights can give their clients tips for helping them install and use the devices correctly. More help could be received from aviation officials. In general, the items are placed in clusters of minimum two pieces. The best implementations of a beacon may be on wind turbines, tall buildings, cranes and chimneys. Before the use of LED, incandescent filament bulbs were used for guidance.

Obstruction lights are not meant only for planes, but also for helipads, on the ground or on buildings. The visibility can extend for a few miles, especially if the lamps are placed on tall structures. Indicator lamps can have different light intensities, such as low, medium, or high. Red markings can light continuously, or using pulses. Xenon technology can be used for white spot items.

Some companies offer energy efficient LED solutions that are solar powered. For mounting the devices to the ground, there is special attachment hardware. The body of a lamp is made from materials that are highly resistant to environmental agents. Cast aluminum could be one of the best materials for a device body. The visibility could be improved by quality lens and the items can be bought already wired, for rapid installation.

According to the International Civil Aviation Association, obstruction lighting is meant for ensuring guidance and safety for pilots. LED beacons are very intense and they can prevent pilots from entering hazardous situations. If the placement of the devices is made considering the standards in the field, accidents can be avoided.
