  FORWARD THROW
  6-36. This refers to the effect of inertia on a falling object. An object that leaves an aircraft moves at the
  same speed as the aircraft. The parachutist (or bundle) continues to move in the direction of flight until the
  dynamics of gravity and the parachute take effect. The forward throw distance is the distance along the
  aircraft flight path traveled by a parachutist or cargo container after exiting the aircraft, until the parachute
  fully opens and the load is descending vertically. Forward throw distance for rotary-wing and STOL
  aircraft equals half the aircraft speed (KIAS), expressed in meters. Table 6-9 shows the forward throw
  distance from a fixed-wing aircraft.
  Forward Throw Distances for Fixed-Wing Aircraft
  Load C-5 C-130 C-17
  Personnel or Door Bundle 229 meters (250 yd) 229 meters (250 yd) 229 meters (250 yd)
  Heavy Equipment 668 meters (730 yd) 458 meters (500 yd) 640 meters (700 yd)
  CDS N/A 503 meters (550 yd) 663 meters (725 yd)
  TTB N/A 147 meters (160 yd) 147 meters (160 yd)
  NOTE: To convert yards to meters, multiply yards by 0.9144.
  To convert meters to yards, divide meters by 0.9144.
