The AXIS Tool

Exit Separation Calculator

takes three variables into account to determine the minimum exit separation in seconds between two groups of jumpers:

1) Group size:
Two seconds are added if a group consists of more than 5 jumpers.

2) Ground Speed:
The speed of the aircraft over ground in knots. You should be able to get this information from the pilot.

3) Intended Group Separation:
Enter the intended group separation in feet. Be aware that the calculator uses 1,000 ft as the minimum separation.

Result:
The exit separation in seconds is displayed above the aircraft. Belly formations should jump before freefly formations.

Jumpers should continue to observe basic safety practices such as proper exit order, facing perpendicular to the line of flight when tracking / angle flying, and/or attempting new free-fly maneuvers.

Tracking-off high for an extended period of time may also influence horizontal separation amongst groups.
