A heliport beacon is essential when long-distance visual guidance is required and no other visual aids are available, or when identifying the heliport is difficult due to surrounding lights. It should be installed above or near the heliport, preferably in an elevated position, to prevent glare to pilots during short-range approach phases.
The beacon emits a flashing light, white, green, or yellow depending on the heliport type, providing a clear and recognizable visual signal for air traffic in night or low-visibility conditions.
