Which of the following scenarios requires a rear riser turn?

A rear riser turn is used primarily to make immediate heading changes while under canopy, particularly after deployment. This technique involves pulling down on the rear risers of the parachute to initiate a turn that can efficiently redirect the canopy’s heading. It is particularly useful for making quick adjustments in flight, especially when a jumper needs to reposition due to unexpected factors such as wind conditions or obstacles.

In contrast, other scenarios do not call for a rear riser turn. For instance, unstable ground conditions do not necessitate this maneuver, as ground preparation typically occurs once the parachute is under control and stable. Similarly, preparing for a landing often involves flaring and utilizing front risers for descent control, rather than rear riser turns, which are mainly for direction changes. Lastly, during freefall, the concept of turns is irrelevant since these maneuvers are performed while the parachute is deployed and in the air.
