In sling load operations, how far must the signal person be from the helicopter?

In sling load operations, the signal person must maintain a distance of at least 20 meters from the helicopter. This distance is critical for several reasons, primarily related to safety and effective communication during the operation. The area around helicopters can be hazardous due to rotor wash, noise, and the potential for debris to be blown around. Being at least 20 meters away minimizes the risk of injury from these hazards.

Moreover, the distance allows the signal person to have a clear line of sight to the helicopter and the load operation. This positioning is essential for giving correct hand signals and ensuring that the helicopter pilot has a clear view of the situation on the ground, contributing to a successful and safe lifting operation. Maintaining this distance is a standard safety protocol in aviation operations to protect personnel and ensure efficiency in sling load execution.
