What is the effect of exceeding the moderate wind restriction on tie down chains?

Exceeding the moderate wind restriction can lead to the chains not holding properly. In windy conditions, the forces exerted on tie down chains can increase significantly, which may exceed the design capability of the chains and their connections to the aircraft. This improper holding can result from either the chains slipping or the aircraft moving against the restraints, leading to an inadequate hold on the aircraft.

Understanding the limitations of tie down systems in relation to wind conditions is important for maintaining aircraft safety. Inadequate tie-down can create risks of damage not only to the aircraft itself but also to other items and personnel in the vicinity. The other choices do not accurately represent the safety concerns and mechanics involved in the failure of tie-down chains under excessive wind, as they either imply complete failure or incorrect conditions regarding aircraft movement.
