- Payload drag coefficient of the dropped object
- The drag coefficient (cd) is the typical drag constant for air. It is in general object specific, but the closest primitive shape to the actual object should give good results: http://en.wikipedia.org/wiki/Drag_coefficient

- Drop precision
- If the system is closer than this distance on passing over the drop position, it will release the payload. This is a safeguard to prevent a drop out of the required accuracy.

- Plane turn radius
- The planes known minimal turn radius - use a higher value to make the plane maneuver more distant from the actual drop position. This is to ensure the wings are level during the drop.
