What do the colors green, yellow, and white indicate in a lighted heliport?

The colors green, yellow, and white on a lighted heliport are specifically designated to indicate various aspects of the heliport landing area.

Green typically refers to the area that is safe for landing and takeoff, serving as a visual cue for pilots. Yellow is often used for marking areas that need caution and highlight approach routes or limitations in space. White lights usually mark the edges of the landing area to enhance visibility, especially during low-light conditions.

These color codes are important for ensuring the safety and efficient operation of heliport landings, as they provide clear and standardized visual guidance to pilots approaching the landing zone. This use of color coding is particularly critical in facilitating safe operations and preventing accidents, especially in congested or complex environments.
