Obstacle lighting and marking is conducted in order to reduce the risk of accident. Obstacles illuminated and marked according to regulations are disclosed in the form of information to pilots in the Airman’s Information Manual (AIP), who can thus identify them on the ground. The choice of lights depends on the position of the objects in the directions of the air routes, in the area of the airport or the heliport, but also outside these areas. The omnidirectional red lights must be double, since in the case of a light source failure, the back-up light must automatically be switched on, which can be incorporated in the lamp itself. In most cases, for marking of tall obstacles (chimneys, antennas, high-rise buildings, power lines, etc.) double low-intensity LEDs of 10 cd and 32 cd are used.
Medium-intensity lights of more than 2,000 cd with LED technology must emit a flashing light.
High intensity lights of more than 20,000 cd are equipped with xenon bulbs and emit a flashing light.
For the marking of the power lines, special low-intensity lights of more than 10 cd and 32 cd are used, which use the magnetic field energy of the conductor.
Medium or high-intensity flashing lights are used to mark high-rise buildings or terrain elevations in the vicinity of the airport approach corridors.
