How many chains are recommended for heavy weather conditions?

The recommendation for using 20 chains in heavy weather conditions is based on standard practices for ensuring adequate stability and safety in adverse weather. In aviation operations, particularly in areas prone to strong winds or severe turbulence, having a sufficient number of chains helps secure equipment and aircraft, preventing them from being displaced or damaged.

Using 20 chains provides a robust safety margin, allowing for secure anchoring under challenging conditions. This number is often determined based on factors such as the weight of the equipment or aircraft being secured, the expected wind forces, and the overall environmental conditions.

By adhering to these guidelines, personnel can ensure that they are prepared for heavy weather scenarios, mitigating the risks associated with unsecured equipment and enhancing operational safety.
