What are the tie-down requirements for ashore operations?

The tie-down requirements for ashore operations are defined to ensure the safety and security of aircraft on the ground. In this context, the correct answer specifies the number of tie-downs required in different weather conditions: 3 for intermediate winds, 6 for moderate winds, and 12 for heavy weather. This breakdown helps flight line personnel to adequately secure the aircraft based on anticipated weather conditions, thereby preventing potential damage from wind or other environmental factors.

The rationale for the specified numbers takes into account the strength of wind conditions and the aircraft's susceptibility to movement. Intermediate winds might not require as many tie-downs since the threat of being moved is less significant; however, as winds become moderate and heavy, the risk increases significantly, necessitating more tie-downs to ensure stability and safety.

The other options suggest different requirements that do not align with standard procedures or guidelines for aircraft tie-downs during ashore operations. Adhering to the specified requirement of 3, 6, and 12 tie-downs helps ensure compliance with safety protocols and protects both personnel and equipment.
