Characteristics Of Aviation Obstruction Lights


The application and classification of aviation obstruction lights

1, medium light A type aviation obstruction light for the white flash, the effective light intensity 20000cd-2000cd, for more than 105 meters of buildings and facilities and background light strong obstacles or with the high light intensity B type light with light use.

2, the light intensity B type aviation obstruction light for the red flash, the effective light intensity 2000cd ± 25% for 105 meters below the buildings and facilities or with the light intensity A type, high light A type of aviation obstruction lights with the use.

3, high light intensity A type of aviation obstruction light for the white flash, and in the day, evening or dawn and night all daylight light flash, the effective light intensity were 200000cd ± 25% day; Aviation Obstruction Light evening or dawn 20000cd ± 25%; night 2000cd ± 25 %; Mainly used for more than 150 meters above the building and its facilities to use, or in the light of aviation obstruction lights with the use.

4, high light intensity B type aviation obstruction light for the white flash, and in the day, dusk or dawn and night all-weather variable light three-layer synchronous flash, the effective light intensity were 100000 cd ± 25% day; evening or dawn 20000cd ± 25%; Night 2000cd ± 25%, mainly used to mark the wire, Aviation Obstruction Light cable tower and high voltage transmission line tower.

1, high light A type aviation obstruction light for the white flash, and in the day, evening or dawn and all-weather nighttime light intensity, the effective light intensity were 200000cd ± 25% day; evening or dawn 20000cd ± 25%; night 2000cd ± 25 %; Mainly used for more than 150 meters above the building and its facilities to use, or in the light of aviation obstruction lights with the use.

2, the solar aviation obstruction light is a bright or flashing red obstruction light, to mark the potential dangerous obstacles to aviation, such as the tower (telecommunications, GSM, microwave & TV), cranes, chimneys, buildings , Open-air large-scale sports field lighting lighthouse, Aviation Obstruction Light high-voltage transmission tower.

3, the aviation obstruction lights are generally divided into low light intensity, light intensity and high light intensity three, the barrier signs of the vertical and horizontal distance of more than 45 meters of buildings and their facilities, you can use the three obstacles lights can be used in conjunction with each other.

According to MH / T60121999 International Civil Aviation Organization issued the "International Standards and Recommended Measures Airport" Annex XIV, aviation obstruction lights sub-low-light aviation obstruction lights, medium light aviation obstruction lights and high light strong aviation obstruction lights three categories:

1, low light strong aviation obstruction light for the constant light, red, peak light intensity greater than 32.5cd, generally not used alone, and must be in the light intensity, Aviation Obstruction Light high light barrier with the use of obstacles.

2, medium light aviation obstruction light according to the requirements of light is divided into three kinds: (a, in the light A type of aviation obstruction lights for the white flash, b, light B-type aviation obstruction lights for the red flash).

3, high light strong aviation obstruction light according to the requirements of light is divided into two kinds: (a, high light A type aviation obstruction light for the white flash, b, high light B type aviation obstruction light for the white flash).

The arrangement of the obstructions of the obstructions: the obstructions of the obstructions shall be marked with the obstructions of the obstructions and the most marginal (ie, as high as the width).
