How many static line slack retainer bands must be attached to the static line slack retainer loop?

The correct answer is that two static line slack retainer bands must be attached to the static line slack retainer loop. This requirement ensures that the static line is properly secured and organized during the jump, facilitating a safe exit from the aircraft and minimizing the risk of entanglement or mishaps once deployed. By utilizing two bands, the static line is held in place effectively, allowing for smoother deployment and control of the parachute.

The use of two bands also aligns with safety protocols and standard operating procedures, reinforcing the importance of double-checking equipment and ensuring that everything is in order before a jump. This redundancy serves as an additional safety measure, providing greater assurance during operations.
