What should be done for dust control during a landing operation?

For dust control during a landing operation, wetting down the area is the most effective approach. This technique involves using water to dampen the surface, which helps to minimize the potential for dust particles to become airborne. Dust can pose significant visibility issues and respiratory hazards for personnel and may interfere with the safe operation of aircraft during landing procedures. By wetting the area, airborne dust is significantly reduced, providing a clearer and safer environment for the operation.

In contrast, leaving the area dry can lead to increased dust production, which can compromise safety. Covering the area with tarps may not be practical for dust control during an active operation, as it does not directly address airborne dust created by the rotor wash of the aircraft. Similarly, while sandbags can aid in controlling water runoff or protecting specific areas, they do not effectively mitigate dust if the ground remains dry and loose. Therefore, wetting down the area remains the best practice for ensuring a safe landing environment.
