Canopy
Skills Drills
By Brian Germain
Learning to fly our parachutes is
absolutely necessary for long-term survival in this
sport. The philosophy that the canopy is simply
a means to get down from a skydive is gradually
becoming a thing of the past. This may be as a result
of individuals with such an attitude dropping out
of the sport due to canopy-related injuries, or
from the insurmountable fear that comes as a result
of a lack of control over their experience. Regardless,
many jumpers have been taking an increased interest
in flying their parachutes better.
Reading and talking about canopies is the beginning
of this process. We must understand the principles
that allow our canopies to fly. To make a real difference
in our capabilities, however, we need to physically
experiment with our parachutes in flight. We must
practice in the real world.
Here are a few exercises that will increase your
abilities to save your own life, and enhance your
feeling of control while under canopy:
Pitch Control Exercises
- Manipulate the canopy on the pitch axis using
the brakes.
- Look at canopy to notice the amount of pitch
axis change.
- Notice the difference between “soft”
and “sharp” inputs:
{slow application vs. quick}
Why?
Controlling the pitch angle is how we manipulate
the angle of attack of the wing. Without a dynamic
change to the angle of attack, we will be unable
to increase the lift of the parachute enough to
change the direction of flight from its normal full
flight glide to level flight. This maneuver is essential
for safe landings.
Pitch Control With Bank Angle
- Begin a turn using a single steering toggle
- Apply the opposite toggle while still in the
turn
- Experiment with soft versus sharp inputs to
negate decent.
- Look at canopy to notice pitch changes.
Why?
Having the ability to control the pitch axis while
in a bank is what gives the pilot the ability to
control the decent rate while in a turn. The natural
tendency is to loose altitude in a turn, but this
is not necessarily the result of turning with bank
angle. By increasing the angle of attack while in
a bank, we can increase the amount of lift that
the parachute is producing, and even alter the flight
path to level flight despite significant bank angle.
Dive Arrest: Toggle Turns
- Place the canopy in a spiral dive using a single
steering toggle
- Arrest the dive as quickly as possible by sharply
applying the opposite toggle as well as the inside
toggle; the inside toggle is not applied until
the two are matched in the degree of input. When
the toggles are matched, a short stab of collective
brake pressure is usually all that is needed to
achieve level flight.
- Exercise both banked recovery and wings level
recovery.
Why?
Turning too low is the preliminary cause of many
injuries in our sport. Unfortunately, most canopy
pilots assume that bank angle must be eradicated
before arresting the dive. This leads many to waste
valuable altitude in the process of leveling the
wing. In situations with very little altitude remaining,
this may delay the collective brake application
until it is too late. By rehearsing a transition
to zero decent while still in a bank, the pilot
becomes accustomed to applying the toggle on the
outside of the turn as a learned instinct, reducing
the chances of a turn leading to serious injury.
Dive Arrest: Front Riser Dive
- Place the canopy in a dive using the front risers.
- Rehearse dropping the front risers and quickly
stabbing the brakes.
- Rehearse both straight front riser dive recovery
as well as turning dives.
Why?
While acceleration on final approach can be great
fun and usually leads to longer swoops, the acquisition
of speed is not really the hard part. What keeps
us alive is the judgment and skills necessary to
save us when we dive the canopy too close to the
ground. If we rehearse the solutions to the dangers,
the likelihood of a dive resulting in serious injury
is reduced. Letting the front risers up slowly may
be the best way to get a long swoop when the dive
is rounded up slowly and with ample altitude. Unfortunately,
this muscle memory may not serve us when we are
really low. In the time it takes to smoothly let
up on the front risers we may find ourselves planted
in the ground like a shrubbery. Dropping the front
risers allows the pilot to keep their hands down,
ready to stab the brakes aggressively to arrest
a mortal dive. A short, sharp, shock on the brakes
may be all that is necessary to place the jumper
back under the wing, and to the higher angle of
attack that saves their life.
Slow-Flight Practice
- Place the canopy in 90% brakes and hold for
60-90 seconds.
- Make controlled heading changes of 45-90 degrees.
- Notice the difference in responsiveness as compared
to full flight turns.
- Notice that lifting a toggle on the outside
of the turn reduces the risk of stalling the wing
on the inside of the turn.
Why?
Most pilots spend the majority of their canopy ride
in full flight. This means that the feeling of the
canopy in this mode is most comfortable to most
people. It also means that flying in deep brakes
places many out of their comfort zone. This means
that most people are feeling somewhat uncomfortable
just prior to putting their feet on the ground every
single jump. In fact, this anxiety often causes
people to hold their breath, and then offset their
steering toggles toward the end of the landing in
order to get to the ground sooner. They simply want
this part to be over. In order to land with great
consistency, we must become intimately aware of
the flight performance of our parachutes in very
deep brakes. The more time we spend in this flight
mode, the more comfortable we will be. If we are
to land well, we must be as comfortable with deep
brakes as we are with full flight.
