Star standard product of obstruction light used in Airport

 

Aviation obstruction lights are usually divided into low intensity, medium intensity and high intensity. The vertical and horizontal distances of greater than 45 meters, and the three types of obstruction lights can be used in conjunction with each other. Aviation obstacle indicator classification. Below 45 meters above the ground, low-intensity obstruction lights should be set up in relatively open surroundings, which is bright red.

 

 

Buildings and facilities 45 meters above the ground and 105 meters below the ground: use medium-intensity aviation obstruction lights as red flashing lights. For buildings and their facilities above 150 meters from the ground, use obstacle signs and must be white flashing lights. The light intensity depends on the brightness of the background.



 

Obstacles should mark the apparent height and width of the obstacle. The distance between the middle layer of obstruction light must be no more than 45 meters, and the height should be more than 100 meters. The vertical and horizontal distances of obstruction lights should not be greater than 45 meters. For chimneys the top obstacle marker light should be located between 1.5-3 meters from the top.

 

 

The obstruction light s indicator should be located 4-6 meters below the chimney mouth.

Ultra-high objects higher than 150 meters should be used in conjunction with medium and high-intensity obstruction lights. For high-voltage power   cables and towers less than 150 meters high, a white light-emitting obstruction light can be installed on the top.

 

 

Regardless of the obstruction lights,the number and arrangement of the aviation obstruction lights at different heights should be able to see the object or the “group outline” of the object from all aspects, and considering the sequential flashing of the obstruction lights to achieve Obvious warning effect.

 

The low-intensity obstruction light is constant light, red, and the peak light is stronger than 32.5cd.Usually, it is not used alone, but must be used in Coexistence with medium-intensity and high-intensity obstruction lights. For example, the buildings and facilities above 45 meters are supplied with multi-layer medium-intensity or high-intensity obstruction lights, and low-intensity obstruction lights can be set between medium-intensity or high-intensity obstruction lights.

Medium intensity obstruction lights are divided into three types requirements:

a. The medium-intensity A-type obstruction light is a white flash with an effective light intensity of 20000cd-2000cd. It is used for buildings and facilities above 105 meters and obstacles with strong background light b. The medium intensity B-type obstruction light is a red flash, and the effective light intensity is 2000cd±25%.

C. Medium intensity C-type aviation obstruction light is red constant light, effective light intensity is 2000cd±25%.

What should you know about Airport wind sock?

The windsock is a cost-effective but useful piece of kit which can indicate wind velocity and direction. Wind socks are often found on airport runways and provide pilots and airport staff with important information about wind directions and speeds. Wind socks can also be found in manufacturing plants where toxic materials or gases are used. The direction of the wind sock can tell staff which way the wind is blowing any chemicals. Windsocks may also be found on motorways or other public areas. When used on a boat, the product can be a useful aid in navigation. A windsock is sometimes known as a wind cone. Contemporary windsocks originate from Japan and China, and are usually manufactured using a high quality silk or paper. A windsock is a conical shaped textile tube, which resembles a giant sock. Hence it’s name: windsock. It’s designed to indicate wind direction and relative wind speed. It’s normally placed next to the runway or a helipad, so that pilots can easily see it afte

Utility of Obstruction Light in Airport

  Obstruction Light Intensity Levels There are three levels of light intensity are utilized to mark aviation obstructions. These are low, medium and high. The objects which are not higher than 45 meters are marked by low-intensity lights. Medium-intensity lights are utilized to mark high buildings, constructions or natural things.

Things to know about Obstruction light

       Aviation lights are usually ided into low intensity, medium intensity and high intensity. The vertical and horizontal distances of aviation lights are greater than 45 meters for buildings. The three types of obstruction marker lights that are used in conjunction with each other. Below 45 meters above the ground, low-intensity aviation obstruction lights is set up in relatively open surroundings, which are always bright red.   Use medium-intensity A aviation obstruction light above 105 meters above the ground and below 150 meters. Obstacles should mark the highest point and the extreme edge of the obstacle. The distance between the middle layer must be within 45 meters, and the height of the city should be within 100 meters. Special consideration must be given to adding aviation obstruction lights to the middle floors of buildings. The obstacle indicator light must be located 4-6 meters below the chimney mouth. Ultra-high objects higher than 150 meters can be used in conjun
