Contexto
Elevated aeronautical ground lights within the movement area shall be marked so as to be conspicuous by day. Obstacle lights shall not be installed on elevated ground lights or signs in the movement area.
The apparent discrepancy arising from the description of both of these examples as being high-intensity lights can be explained by noting the level of illumination at the eye when the lights are viewed from a typical operational range. Thus in good visibility conditions, a 200 000 cd obstacle light seen from a range of 3 km will provide a similar illuminance at the eye to that provided by a 20 000 cd approach light seen from a range of 1 km. In other words, a pilot will describe both types of lights as being high-intensity.
