Within what approximate radius of an aerodrome does the guidance consider that high-intensity obstacle lights may dazzle pilots?

Within approximately 10 000 m radius of an aerodrome.

For fixed objects with a height of 150 m or more above ground level, which two alternative lighting configurations are recommended when high-intensity Type A lights are unsuitable due to dazzle or environmental impact?

Medium-intensity obstacle lights, Type C, used alone, or medium-intensity obstacle lights, Type B, used either alone or in combination with low-intensity obstacle lights, Type B.

Q: What should be used instead of high-intensity Type A obstacle lights at night if they could dazzle pilots near an aerodrome or cause environmental concerns?

Medium-intensity obstacle lights, Type C, should be used alone, or medium-intensity obstacle lights, Type B should be used either alone or in combination with low-intensity obstacle lights, Type B.

ED Decision 2016/027/R

Where, the use of high-intensity obstacle lights, Type A, at night may dazzle pilots in the vicinity of an aerodrome (within approximately 10 000 m radius) or cause significant environmental concerns, medium-intensity obstacle lights, Type C, should be used alone, whereas medium-intensity obstacle lights, Type B, should be used either alone or in combination with low-intensity obstacle lights, Type B.
