|Clean Up Your Turns
|By Brian Germain
"Turn coordination" is a topic that, until recently, has
been mostly unapplied to ram-air parachute aerodynamics. In simplest terms,
this refers to the degree to which a flight vehicle is aligned to the relative
wind during a turn. Another way to look at this is the degree to which a
turning aircraft is pointed at the relative wind with regards to the yaw axis.
A "clean turn",
from an aerodynamic perspective, is one that keeps the nose of the aircraft
pointed at the relative wind throughout the turn. When flying airplanes, this
prevents the passengers from spilling their drinks, as well as saving fuel and
preserving airspeed. In parachutes however, this aspect of turning has mostly
been ignored. As parachutes become faster and faster, the time has come to
begin thinking about this aspect of our canopy flight for several very
The first has to do with the ability
of the pilot to level off at any point during the turn. Lets face it, sometimes
the ground creeps up on us. Flying an aerodynamically sound turn increases the
likelihood that you will be able to convert your airspeed into lift in a timely
manner. If you are sliding sideways through the sky because you are simply
jamming a toggle down, you are not prepared to interface with the planet. The
relative wind is jumping across the bumps on your parachute, creating turbulent
flow, while the suspension line load is getting shifted to one side of your
canopy. When you attempt to stab out of an uncoordinated turn, there is a
hesitation before the parachute begins to change direction and level off. If
the ground gets to you before this happens you may find yourself watching Oprah
in your hospital bed for a while (not that I have anything against Oprah).
The second reason for flying a
coordinated turn has to do with overall parachute stability. In an
uncoordinated turn, the nose of your parachute is not pointed at the oncoming
relative wind. It is sliding sideways. This means that the pressure in your wing
is being compromised, in addition to the wingtip on the outside of the turn
being presented to the relative wind. If you hit turbulence during this kind of
"sloppy" turn, you are much more likely to experience a collapse of this side
of the parachute. In other words, if you are turning right, your left wing more
likely to fold under. Interestingly, when an aggressive, uncoordinated toggle
turn is released, the opposite tends to happen. When the right toggle is
released, the right wing surges forward as the drag is released and it is
presented to the relative wind, opening the door for a collapse on right side
of the parachute. Either way, this can result in way too much daytime TV.
There is a fundamental problem with
the way in which most of us were taught how to turn our parachutes. They said:
"if you want to turn right, pull down the right toggle." Simply pulling on a
toggle increases the drag on the right side of the parachute, retreating that
wing tip. At the beginning of the turn, it is purely "yaw" energy. It is like
the pilot of an airplane stepping on the rudder pedal. As a discrete action,
steering toggles are an incomplete input. We need some "roll" energy.
The harness is more than a way to
attach the jumper to the parachute. It is also a way to manipulate the canopy
itself. If the right leg reaches for the earth as the left hip reaches for the
sky, the parachute will turn to the right. It is true that smaller parachutes
will respond quicker to such inputs than larger ones, with elliptical canopies responding
the quickest, but harness input will have an affect all parachutes. Most
importantly, when used at the initiation of a turn, harness steering converts a
toggle turn into a coordinated maneuver. This is true if you are under a Lotus
190 or a Samurai 95.
When flying an airplane, all turns begin by initiating roll energy with
the ailerons, (rotating the yolk), followed by an application of the rudder to
coordinate the turn. The old airplanes had a string on the cowling (hood) to
show the direction of the wind-flow, while newer ones have slip indicators on
the instrument panel. If only we had such information while we were flying our
canopies. Ah, but we do...
Trailing behind your wing is all the yaw axis coordination data you
will ever need. It is called your pilot-chute. If you are flying a coordinated
turn, your bridle will remain parallel to the ribs of your canopy throughout
the turn. If at any point it goes slack, whips around like a snake or drifts
off to one side, you are not flying a clean turn. You are not carving your wing
through the sky; you are skidding out of control. The relative wind is not
following the valleys of your ribs; it is hopping over the bumps, tumbling into
Try this on your next jump: Look up at your canopy while you are flying
straight and simply yank a steering toggle down to the ½ brake position. You
will immediately see what I am talking about as your pilot-chute swings off to
one side. Next, lean in your harness, lifting one leg-strap to yield direct
roll axis input. It may turn and it may not, depending on the wing. This is not
important. Then, while holding the harness input, pull the steering toggle to
turn toward the direction of your harness input. You will notice that the
pilot-chute is trailing straight back, even in a sharp turn.
Once you have experienced your first real coordinated parachute turn,
it is time to develop new habits. This takes time. I find that when learning a
new skill like this, it is best to have a simple way to remember the process.
In this case, try using the following sequence for every turn you make: 1)
LOOK, 2) LEAN and 3) TURN. This is mnemonic was taught to me by a
great paragliding instructor and skydiver, J.C. Brown. Rather than
thoughtlessly jamming a toggle down, look where you are about to
go, lean in the harness to establish the roll, and finally, pull
the toggle down to flow deeper into the maneuver.
When you play with this kind of turn, you will find
that the parachute simply feels better; that you feel more in control over the
wing. You will also find that you can better bump both brakes down during the
turn in order to reduce your decent rate, or even level off completely. While
practice is necessary to perfect the technique, all parachute have the ability
to transition from a descending turn into a level flight turn, into a soft
beautiful landing. If you know how to carve your way out of a low turn, there
will never be a reason to hook into the ground, ever.
Although many skydivers still think of their parachute simply as a
means to get back down to the ground after a skydive, learning how to use the
system the way it was meant to be used will increase the chances that you will
get back down to the ground safely. Gravity pulls equally on those who love
canopy flight as those who abhor it. From twenty years of teaching parachute
flight I have learned this: you can only become great at something that you
love. The more you understand, the more you will explore. The more you explore,
the more you will feel control. The more in control you feel, the more you will
love it. And that, ladies and gentlemen, is what it is all about.

|Choose Your Focus
Choose Your Focus
by Brian Germain
We have a choice about what we focus our minds upon.
Depending on what we hold in the focal point of our consciousness, we may begin
to feel bad, or good. Regardless of the context, the feeling is ultimately what
When we feel bad, we are not constructive. We see nothing but obstacles. When
we feel good, we can solve anything that life throws at us. It is that simple.
This is the reason why it is so important to monitor what we spend our time
When we focus our minds on things that make us feel bad we loose our connection
to the feeling of confidence that comes as a direct result of feeling happy. We
disconnect from our productive, constructive self. Ultimately, this is who we
are. When we are in a negative mood, everything is difficult. When we linger on
a topic that does not bring us to a place of feeling good, we are unable to
solve whatever life has in store for us.
That is not to say that we should throw the baby out with the bathwater, of course.
The negative emotion is a powerful tool that helps us to discover whatever it
is that we truly believe in. We need our emotions to guide us, but as the sole
contributor to the mental processes that determine our actions, negative
emotion is a terrible master.
Negative emotion, be it fear or anger, is an alarm. It tells us what we do not
want. However, negative emotion leads us toward a destructive path that does
not lead to the most positive possible outcome. It simply guides us away from
something undesirable to us. That does not paint a clear picture of what we do
want. It is simply complaining about the current state of affairs, rather than
constructively modifying the situation to what would be a better reality.
When we begin to feel the effects of a thought that makes us feel bad, it is
essential that we find out what the emotion is trying to tell us. As soon as
the goal is accomplished, and that is usually within a few seconds, we must
immediately turn our attention toward a series of thoughts that help us to feel
good. If we do not, we will be powerless to effect things in a positive
It is important that each person take stock in the things that make them feel
good. This may be a specific activity that brings you back to your happy self,
like skydiving, or hanging out in someplace beautiful. It may however, simply
be the thought of one of these activities. It may be the thought of someone
that you love, or a state of affairs in your life that is very much to your
liking. When you are able to conjure this thing in a moment when you are
feeling scared or angry, you are then reconnecting to the part of you that is
an empowered leader of your experience. This is where we reconnect with our
sense of humor, the human way of finding a higher perspective on our lives that
makes us feel better. This skill, above all others, is how we convert negative
emotion into positive flow of mind that cannot be held back by anything.
We must all make a long list of things that we appreciate. We must do this
because it will help us to create more of these kinds of experiences through
the conjuring of the feeling that is at the core of these things. The way you
feel when you are at your best and happiest is the only place from which you
can manifest your reality to become what it is that you want it to become. You
must picture it, feel it, and then envision more of the same. Knowing what you
want is the first step toward creating it.
