During the proning process on a scissor lift, what should the ac and the controller do for safety?

In the context of the proning process on a scissor lift, gripping the outside shoulder strap of the flyers' flight suits is crucial for safety. This approach allows the AC (Assistant Controller) and the controller to maintain control and provide support to the flyers without compromising their balance or safety during the process.

Gripping the outside strap ensures that the individuals being supported have the necessary assistance while also minimizing the risk of accidentally pulling or tugging too hard, which could disrupt the flyers' stability. It provides a secure grip that allows for better control during the transition phase, ensuring the flyers are safely positioned before any flight activity begins.

While other options might suggest alternative forms of involvement, they either do not offer direct support or may place individuals too far from the necessary interaction with the flyers, which can diminish the safety protocols in place during this critical phase of the process.
