How many diagonal back strap pads are required for the parachute harness to be serviceable?

The parachute harness requires two diagonal back strap pads to be considered serviceable. These pads are essential for ensuring that the harness fits securely and comfortably on the jumper. They provide cushioning and support, which helps to distribute the load evenly across the jumper's body during the parachute descent. Having only one pad would not provide adequate support and comfort, potentially compromising both safety and performance. The presence of two pads allows for additional reliability and functionality of the harness, making it suitable for safe and effective parachuting operations.
