Final answer:
The numbers 2+3 U-folds are reduced by approximately 0.70 feet for a skydiver in a feet first position and 1.0 feet for a skydiver in a horizontal position when stowing the quarter deployment bag and canopy on the automatic back parachute deployment.
Step-by-step explanation:
When stowing the quarter deployment bag and canopy on the automatic back parachute, the numbers 2+3 U-folds are reduced by approximately 0.70 feet for a skydiver in a feet first position and 1.0 feet for a skydiver in a horizontal position. These reductions in length help in securing the equipment properly during the parachute deployment.
