Carefully inspect the canopy and suspension lines prior to using the four-line release. If any parachute damage is evident or if there are broken suspension lines, do NOT use the four-line release system.
The four-line release system should not be used at night since parachute damage may be difficult to determine.
To operate the four-line release system, you locate the two lanyard pull loops. They are on the inside of the rear risers. Pull the lanyard pull loops sharply downward (fig 5-14). This takes approximately 20 pounds of pull force. This action frees the rear four suspension lines, which allows the canopy to form a lobe in the rear center and permits a steady escape of air, which reduces

oscillation and allows directional control. By pulling down on the right lanyard, you steer your canopy to the right. To steer your canopy to the left, you pull down on the left lanyard.
Parachuting. - Try to determine the wind direction at the surface by watching white caps or smoke from the aircraft wreckage or known surface winds in the vicinity. Winds at the surface may be quite different from those encountered at altitude. When nearing the water, maneuver the parachute so that you are facing into the wind. Begin preparing for water entry as soon as possible after your chute is opened, because judging your altitude over water is difficult in daylight and nearly impossible at night. Grasp the left main sling webbing with your right hand (fig. 5-15). With your left hand, release the chest strap and left leg strap quick-ejector snap (fig. 5-16). Now grasp the right main sling webbing with your left hand. With your right hand, locate the right leg strap quick-ejector snap and release it upon water entry (fig. 5-17). Your
