21-16. Forward throw is the effect that inertia has on a falling object. When an object leaves an aircraft, it is traveling at a speed equal to the speed of the aircraft. The jumper (or bundle) continues to move in the direction of flight until the dynamics of drag and parachuting takes effect.21-17. To determine the amount of forward throw for rotary-wing aircraft, divide the drop speed of the aircraft in half. This yields the forward throw in meters. (For example, an aircraft flying at 70 knots would have a forward throw of 35 meters.) To determine the forward throw for fixed-wing aircraft, the following distances apply. (See table 21-3.)
