What is the recommended tie down procedure for moderate weather conditions?

The recommended tie down procedure for moderate weather conditions typically involves using 14 chains. This is because moderate weather can include a combination of wind and rain that has the potential to sway and lift the aircraft. The use of 14 chains provides a robust securing method that helps prevent movement or damage to the aircraft, ensuring its stability during such weather conditions.

Each chain plays a critical role in anchoring the aircraft securely to the ground, and using this increased number is a standard practice to accommodate the forces that can act on the aircraft in moderate to adverse weather. It creates a more secure hold that enhances safety by mitigating the risk of damage.

In contrast, fewer chains might not provide sufficient security, leading to possible shifting or displacement in windy or wet conditions, which could jeopardize both the aircraft and ground personnel's safety. Therefore, adhering to the 14-chain standard for moderate weather is essential for effective aircraft tie-down procedures.
