During slinging operations, when using a marshaller, how would you direct him/her to stand?

During slinging operations, the correct approach for directing a marshaller is indeed to have them positioned back to the wind and in plain view. This positioning is crucial for several reasons.

First, facing away from the wind allows the marshaller to have a clearer line of sight for the helicopter approaching and can better gauge the helicopter's position and movement. Being in plain view enables effective communication between the helicopter pilot and the marshaller, ensuring that the pilot can see the marshaller's signals without obstruction.

Moreover, this positioning facilitates safer operations, as a marshaller who can communicate effectively with the pilot can help mitigate risks associated with the sling load, including obstacles and potential interference from wind gusts.

The other options may impede communication or create hazardous conditions. For instance, having the marshaller facing directly in front of the helicopter could limit their visibility and ability to give signals effectively. Being positioned too close could also pose a safety risk in case of sudden movements by the helicopter.
