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 approx-
imately 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
