How many chains are required for normal weather tie down?

For normal weather tie down procedures, the standard requirement is to utilize six chains. This is based on established guidelines that ensure aircraft stability and safety during adverse weather conditions. The six chains provide an adequate level of restraint to prevent movement of the aircraft without unduly complicating the tie-down process.

Using six chains balances the need for secure anchoring of the aircraft while also conforming to safety standards that mitigate risks associated with wind and environmental conditions. More chains than necessary may lead to logistical challenges and increased complexity in tie-down procedures, while fewer chains could compromise the necessary security against potential movement. Therefore, the optimal number of chains for normal weather tie down is six, ensuring that aircraft are properly secured in a standard operating environment.
