What is used to secure the MAAS on concrete for unidirectional engagement?

The use of anchor plates is essential for securing the MAAS (Mobile Aircraft Arresting System) on concrete for unidirectional engagement because they provide a stable and strong attachment point that can withstand high tensile and shear forces. Anchor plates distribute the load across a wider area of the concrete, reducing the risk of failure or damage to the concrete substrate. This method is particularly effective in ensuring that the equipment remains securely positioned and performs reliably during operations, especially in situations where there may be high stress or impact.

In contrast, merely using bolts, screws, or concrete adhesive may not provide the same level of stability and load distribution as anchor plates. While these options have their specific applications, they might not ensure the necessary strength and reliability required for the demands of a system like MAAS, which is designed to safely stop aircraft during emergency landings.
