What is one of the first actions when preparing to fold the wings?

One of the initial steps when preparing to fold the wings is to ensure the wing fold switch is in the correct position. This action is critical because the wing fold switch controls the hydraulic system responsible for the wing folding mechanism. If the switch is not in the correct position, it could lead to unsafe maneuvering or operational issues while attempting to fold the wings.

Verifying the switch's status ensures that all systems are prepared for the wing folding process and helps prevent any potential accidents or equipment damage. This step is essential for maintaining safety and operational integrity on the aircraft before moving forward with subsequent actions, such as checking for hydraulic leaks or notifying flight operations.
