How can jumpers assure adequate separation between groups exiting the aircraft?

The correct method to ensure adequate separation between groups exiting the aircraft involves gauging separation according to position over the ground. This technique is crucial because it allows jumpers to monitor the distance between groups as they fall relative to a fixed point on the ground. By using this approach, jumpers can better account for the speed and trajectory of free fall, ensuring that different groups do not converge during descent. Maintaining awareness of their position over the ground helps jumpers manage their fall rate and spacing, significantly reducing the risk of collisions.

While other methods like timing exits based on altitude or using visual signals can offer some level of coordination, these may not account for environmental factors, such as wind, which can affect descent rates and distances. Similarly, using a predetermined exit order can be useful but does not directly ensure that groups maintain adequate separation during free fall. Hence, focusing on ground position provides a more dynamic and responsive way to adjust spacing as needed.
