In which position do jumpers secure their static line in a CH-47?

Jumpers secure their static line at waist level in the left hand when exiting from a CH-47 helicopter. This position allows for optimal control and reach when preparing to jump, ensuring that the static line can effectively deploy the parachute as the jumper exits the aircraft. Securing the line in this manner helps maintain the necessary tension and alignment required for a successful deployment. Holding the static line at waist level provides the jumper with a stable grip while also allowing for free movement of both hands during the jump sequence. This methodology is critical for safety and performance during aerial operations.
