How do tie-down procedures for aircraft differ in heavy weather compared to normal conditions?

In heavy weather conditions, the tie-down procedures for aircraft are adjusted to ensure maximum stability and safety. The use of more tie-down chains is crucial to withstand the increased forces exerted by strong winds and turbulent conditions. The added chains provide a greater level of security, anchoring the aircraft more effectively to prevent movement or damage during adverse weather.

In contrast, under normal conditions, a standard number of tie-downs may be sufficient to secure the aircraft. However, during severe weather events, the potential for gusts and shifting winds necessitates a more robust approach, hence the increased number of tie-down chains. This adjustment reflects the understanding that heavy weather poses a heightened risk to aircraft stability, requiring additional measures to mitigate that risk.
