The primary difference between static line and freefall jumps lies in how the parachute is deployed. In static line jumps, the parachute is deployed automatically as a result of the static line connected to the aircraft. When the jumper exits the plane, the static line extends and pulls a pin that opens the parachute's deployment bag. This ensures that the parachute is deployed shortly after the exit, typically within a few seconds.

In contrast, freefall jumps involve the jumper free falling for a period before manually deploying the parachute. The parachute deployment is not automatic; instead, the jumper has the control to pull the deployment handle at the appropriate altitude, allowing for personal choice regarding the timing of the parachute opening.

Understanding these differences is crucial for skydiving safety and technique, as it impacts both the approach to exiting the aircraft and the way in which parachute deployment is managed during the jump.
