CF World Record
Big Formations/Fast Formations
(Speed is our friend!)
Canopy Formation record camps in 2002, 2003 and 2005 proved to be far
more successful than we could have imagined, not only from the safe
completion of the planned formations each year but also from the
knowledge that was gained during these events. One of the most
important things that we have learned is quite simply fast flying
formations are typically healthy and therefore safer than a slower
flying formation. The trick is how to engineer and build a fast flying
healthy formation.
In order to keep the formation flying fast we will continue to
implement the prescribed wing loading, line sets, sliders and jumpsuits
that we used at the 2003/2005 event as described at the end of this
article, however we will also be implementing several other items that
will help keep the formation flying fast and help improve our breakdown
and starburst methods. (On and engineering note, we have increased the
size of the people and canopies in our base which will greatly improve
the solidity and glide ratio of the formation.)
Items that will be required of the 2007
world record attendees:
Kill
Cones (or a deployment bag with a #8 grommet)
To continue to decrease drag or
oscillations it will be necessary to
have a kill cone or a deployment bag with a #8 grommet. The kill cone,
which is simply a round piece of fabric with a #8 grommet in the
center, will cover the pilot chute after opening and keep it from
inflating. This inflation causes a slight amount of drag and can also
cause the canopy to slightly oscillate. If this happens to a large
number of canopies the additive effect can have some very serious
adverse effects on the formation. (The deployment bag with a #8 grommet
does the same thing.)
Sliders
In an effort to keep the formation as quiet as possible we will be
requiring mesh or X sliders for this event.
Spider
Sliders (also known as X sliders)
In an effort to speed up the center area
of the formation we will
supply some of the people with a spider slider once their position has
been chosen. (If you have any additional spider sliders please bring
them with you to the event.)
Mesh
Sliders
Everyone else is required to have a mesh slider with the leading edge
folded to reduce vibration. It is an easy 1 minute modification. Fold
the leading edge tape in half at the center and sew at an angle towards
the grommet tapering to no fold then back to the center and on to the
other corner and back to the center. It's that easy and makes the
slider totally quiet.
Radios
Radios for the event will be furnished by
the committee. They also will come with a standard ear bud type
headset. You may bring your own ear piece or headphone mounted inside
your helmet. The plug must be the standard 3.5 millimeter STEREO plug.
(the mono plug will not work at all) You will also want to think about
how to mount the radio to yourself.
Items
that were required of the 2003/2005 world record attendees:
Wing
Loading
This year we will be
using a wing loading of 1.300 - 1.375 lbs/sq ft.
Wing loading is calculated by dividing your total exit weight by the
size of your canopy. The following chart gives the appropriate exit
weights for the given canopy sizes. If you fall between the shown
weights of 2 different canopies then it will be necessary to wear some
weight to get you in the range of the next size up canopy.

Line Sets
Performance Designs has spent many hours
working with us do determine
what line sets work better for building large canopy formations. We are
also currently testing ways in which we can speed up the formation in
order to maintain its health and avoid cupping.
Following are the requirements for line sets:
We will be using PD's Sequential line set trim!
Line lengths for the given sizes are listed in the chart below.

Jumpsuits
In an effort to keep the formation flying
as fast as possible jumpsuits
will be required. The specifications for jumpsuits will be as follows:
1) No grippers or RW booties
2) Nylon front
3) Spandex on sides and back to keep the front pulled tight
4) Spandex arms
5) Reinforced knees and seat (if desired)
In closing I would like to stress that we are continuing to do
everything we can to keep the formation flying as fast as possible, as
this will help keep the formation as healthy as possible. We will
continue to try and minimize our risk while building large canopy
formations as we work towards our goal of a 100-way in the future.

Chris J. Gay
