What is the tie down requirement for heavy weather conditions?

The tie-down requirement for heavy weather conditions is set at 20. This higher number is designed to ensure that aircraft are secured adequately during extreme weather events, such as storms or high winds. The rationale here is that the forces experienced by an aircraft in severe weather can be significantly greater than in normal conditions, necessitating additional tie-down points to prevent movement or damage. Each tie-down point helps to distribute forces more evenly, providing an extra layer of stability and safety for the aircraft.

In contrast, the lower numbers suggest insufficient tie-downs for such conditions, which would not adequately account for the increased risk of aircraft displacement during heavy weather. Therefore, adhering to the requirement of 20 tie-downs is a crucial part of ensuring the safety of the aircraft and its structural integrity in adverse weather scenarios.
