How many people are required when folding the tail pylon?

The correct answer is based on the established safety and operational procedures for folding the tail pylon. Folding the tail pylon of a helicopter is a critical operation that requires a specific number of personnel to ensure safety and proper handling. This process typically involves several steps that necessitate coordination among team members, including guiding the movement of the pylon, monitoring mechanical components, and ensuring overall safety protocols are followed.

In this context, having five people ensures that there are enough hands available for the various tasks involved. One person can operate the folding mechanism, while the others assist in stabilizing the helicopter and communicating during the operation. This setup allows for effective teamwork and reduces the risk of accidents or mishandling of equipment.

It's important to follow this guideline strictly, as it is designed not only to facilitate the operation but also to maintain safety within the work environment. The number of personnel required is specifically determined to prevent unnecessary strain on individuals and to have adequate coverage for all necessary positions during the operation.
