The main purpose of tie-down assemblies is to secure aircraft and support equipment. These assemblies are critical in ensuring that aircraft remain stable and stationary when not in operation, particularly in environments where wind or other conditions could cause movement. By using appropriate tie-down assemblies, the risk of damage to both the aircraft and surrounding equipment is minimized, thus maintaining safety and operational integrity.

Choosing tie-down assemblies is particularly important during maintenance periods or when an aircraft is parked for an extended duration. While other options may relate to the broader context of aircraft operation or maintenance, they do not specifically address the primary function of tie-down assemblies, which is focused on securing and stabilizing the aircraft and its support equipment against external forces.
