Why is it important to track perpendicular to the jump run when making tracking jumps from a large plane?

When conducting tracking jumps from a large aircraft, tracking perpendicular to the jump run is crucial for maintaining safety and ensuring that the jumpers are spaced properly in the air. By tracking perpendicular, jumpers can effectively manage their horizontal separation from other groups that may have exited the aircraft either ahead or behind them. This helps minimize the risks of collision or interference during freefall, since groups that track parallel to the jump run are likely to close in on one another, increasing the chances of accidents.

Tracking in this manner allows jumpers to maintain a safe distance from one another, which is essential for the integrity of the jump and the safety of all participants involved. This practice not only enhances safety but also improves the overall execution of the jump, making for a more successful and enjoyable experience.
