What is the standard method for marking a HLS for helicopter landings?

Using colored smoke or panels is the standard method for marking a helicopter landing site (HLS) because it provides a highly visible and easily recognizable signal to pilots. Colored smoke, in particular, can be utilized to mark the landing zone effectively, even in various weather conditions, and it helps distinguish the site from its surroundings. This visual cue is crucial for ensuring a safe and efficient approach for helicopters, allowing for quick identification of the designated landing area.

Colored panels can also be used effectively, as they can be placed on the ground to create a clear and easily understandable symbol indicating the landing site. The visibility of these colors against the natural terrain aids pilots in safely navigating and landing in the correct location.

Other methods, such as deploying flares or using reflective tape, can be useful in specific scenarios but are not considered standard for primary HLS marking. Flares may provide temporary visibility but do not offer a continuous signal; reflective tape is often less visible from the air in certain conditions. Handheld lights can guide pilots but generally serve more as a secondary aid rather than a primary marking method.
