If the flyers are aloft and cannot release, what is the proper procedure?

When flyers are aloft and unable to release, using the hydraulic bypass valve to lower them is the correct procedure. This method is specifically designed to safely and efficiently lower the flyers back to the ground when they cannot release themselves. The hydraulic bypass valve allows for controlled descent, ensuring that the process is both safe for the flyers and compliant with operational protocols.

Utilizing the manual winch is not advisable in this scenario, as it could lead to an uncontrolled or jerky descent, increasing the risk of injury. Calling for external help would unnecessarily delay the rescue process and could lead to complications if immediate actions can be taken. Waiting for the flyers to release themselves is not a viable option since it may not happen, and the safety of the flyers is the primary concern. Thus, engaging the hydraulic bypass valve ensures a prompt and safe resolution to the situation.
