The TR 27 requires active flying in turbulences! This can avoid canopy closings and deformations.

Warning

For best performance during your flight, it is important to be always sensitive to what your

canopy is trying to communicate. The key elements of active flying are the advancements and

tension control. When the canopy moves ahead of you, carefully apply the brakes, so that the

canopy returns to be above you, and if the canopy moves behind you, you must release the

brakes. Flying with the brakes lightly applied (+ - 20 cm) allows the canopy to fly slightly behind.

In turbulent circumstances the internal paraglider tension may change, which you will feel

on the brakes. The idea is to maintain a constant tension, and in case you feel loss of tension,

apply the brake.
Avoid flying excessively with the brakes on because you might brake to the point of stopping

the canopy from flying. Always consider your aerodynamic speed. Your movements can be

symmetric or asymmetric and both or one brake can be applied. We suggest that you do ground

practice runs and advancing simulations. Tension loss can be simulated well on the ground.

By pulling simultaneously the external riser A’ at about 18 cm, the canopy tips will close. The

canopy remains completely maneuverable through the activating of unilateral brakes or the

shifting of weight towards the risers, flying at a fast descending rate (up to approximately

5m/s). In order to recover, the pilot must release the external riser A’ lines. Usually the canopy

re-opens by itself, but the pilot can assist with a long and quick pumping.

Spirals carry a high rate of descent. Therefore, high accelerations (G) make it impossible to

hold them for an extended period of time. The spiral force may cause the pilot to faint and to

lose flying controls, and crash. Furthermore, they will exert a lot of force and affect the pilot

and equipment alike.
The pilot should never exercise this maneuver in turbulences or with wide lateral angles. In

windy conditions, the pilot must be aware of oscillations during the maneuver.
When the pilot activates just one brake, slowly and progressively, the paraglider inclines

sideways in a sharp angle and enters a steep and quick turn, which may become a positive

spiral.
During a spiral the rotation radius can be controlled by the greatest or smallest force applied

to the inside brake.
To come out of it, the pilot must release the brake slowly and shift his/her weight lightly to

the outside of the turn. A sudden exit may result in an exaggerated momentum forward of the

canopy and collapsing it. For this reason, on exiting the last turn, the inside brake of a given

turn must be softly applied again.
In case the canopy collapses during this process, the spiral must be counter-acted, as the

active canopy area will be reduced.

It’s very easy to land with the TR 27. The final approach stage must be done in straight line

upwind. During this final glide, the paraglider must be decelerated slowly and at about 1 m

from the ground the pilot must stall the canopy, according to the conditions.
With a strong nose wind, the pilot should break only slightly or eventually don’t even brake at

all, and utilizing just the risers ‘B’ to de-inflate and overcome the canopy after the landing. By

breaking during a landing in strong wind conditions, you may expose the canopy to the wind,

which could lead to the pilot being dragged backwards.
The final approach must be done always in a straight line. Sharp and alternating turns may

produce a dangerous pendulum movement close to the ground.

The TR 27 has not been designed for motorized flight, or acrobatics. This project is designed

for only one pilot without passenger.

•

Neither pilot nor any paraglider are immune to collapses; therefore active flying will

decrease the chances of happening.
