What is the recommended method to approach cargo helicopters like CH-53?

Approaching cargo helicopters such as the CH-53 from the rear at a 45-degree angle while crouching after they have landed is the recommended method because it minimizes the risk associated with the helicopter's rotor wash and potential obstruction from the rotor blades and tail. This approach position allows personnel to maintain a safe distance from the main rotor area while still being able to easily communicate with the crew.

Approaching from the rear at an angle also provides a clear line of sight to the helicopter's crew, which is crucial for ensuring that they are aware of your presence. Crouching reduces your silhouette against the backdrop, making it less likely for you to be struck by the tail rotor or inadvertently enter a hazardous area. This technique is particularly effective in ensuring that both the individual approaching the helicopter and the crew maintain safety throughout the landing and unloading processes.
