SPORT PARACHUTE MAIN PACKING
TECHNIQUES
The most common packing method used today is the
Proper Ram-air Orientation (PRO) packing. Figures 4-1
thru 4-32 show this technique. There are several variations
to this technique designed for special purposes.
Free fall cameramen may require a slower opening to
reduce the opening shock. Canopy Relative Work
(CRW) parachutists may want faster sub-terminal openings.
The rigger should be able to provide guidance to
the parachutist for the type of opening required.
Figure 4-1. Prepare the slider. If collapsible, make sure the
drawstring(s) is cocked.
Figure 4-2. Grasp the line groups between your fingers.
Figure 4-3. Run your hands up the lines pushing the slider
ahead of them. Spread the line groups and shake out canopy.
Figure 4-4. Make sure the canopy is orientated with the nose
to rear and tail to front.This view is shown from the top of the
canopy looking down and towards the packer.

Figure 4-13. Grasp the center of the tail seam with the same
hand that holds the lines. With the other hand, pull the tail
seam downward. Repeat for the other side.
Figure 4-14. Pull both side seams together at the bottom.
Figure 4-15. Roll both seams together tightly starting at the
bottom.

upper material tightly against the lines.

Figure 4-18. Take the free hand and place it under the rolled
canopy bundle.
Figure 4-19. Keeping the lines taut, lay the canopy bundle on
the floor.
Figure 4-20. Triangular shape on the floor. Make sure the
slider is securely wrapped in the tail.

Figure 4-23. Dress the canopy bundle slightly wider than the
deployment bag.
Figure 4-24. Make a short “S” fold at the slider end of the
bundle.
Figure 4-25. Fold the top of the canopy bundle back towards
the lines for a second “S” fold.
Figure 4-26. Complete the “S” fold.
Figure 4-27. Place one corner of the canopy stack in the bag.

When packing reserves and emergency parachutes, the
rigger must adhere to the manufacturer’s instructions
and is not allowed to deviate from them. When packing
main parachutes, the manufacturer may specify a
certain packing method but then gives guidance and
leeway for alternative methods to use to vary the opening
according to the needs of the parachutist.

DEPLOYMENT AND INFLATION
CHARACTERISTICS
Main canopies have changed dramatically over the last
several years and, consequently, different opening
problems have emerged. One of the most common
problems encountered is hard openings. The most
effective method employed to reduce hard openings is
to roll the nose of the canopy to close off the openings
in the leading edge during the initial inflation process.
This rolling technique varies from a single roll to several
rolls. Figure 4-33 shows this technique. If this does
not solve the opening problem, riggers should contact
the manufacturer for advice. Most manufacturers are
very cooperative and have considerable expertise in
working with their products.
In the event the manufacturer cannot resolve the problem,
it may be necessary for the rigger to modify the
slider size, or deployment brake settings. Of these
options, the easiest to do is to change the brake setting.
Reducing the brake setting results in less pressure on
the canopy during opening, thereby reducing the opening
force. The negative effect of reducing the brake setting
is an increase in opening surge. The new brake
