The PLL flashing Heliport Locator Light is used as a supplementary marker for local visual acquisition of the heliport site. It is an economical solution to visually assist the pilot who has arrived in the general area of the heliport site. The PLL may be mounted at the heliport or on an adjacent building or remotely
as an outer marker to acquire the preferred approach where lead-in lights are not practical. It is not intended as a substitute for a heliport identification
beacon when long range site acquisition is needed.
