3.3

POWERED FLIGHT

 

CAUTION: Before each start it is necessary to have a thorough check of the 
wing, harness and power unit (trike).

In powered flight most of the wing characteristics remain as described above 
(chapter 3.2). Still there is additional information needed, concerning power 
output, proper matching of the wing/engine/propeller/trike etc. 

Dudek Paragliders cannot take responsibility for all possible combinations, 
but if you will contact us in doubt, we are always ready to help. 

First flights

In order to get familiar with your wing we recommend flying with trimmers set 
slow, because in this configuration Synthesis Cabrio behaves as a standard 
wing. Flying like that try pulling the brakes until you feel resistance, usually it 
will be at about 1/4 of the range.

Once you feel competent with your wing, you can start experimenting with 
faster trim settings. Learn to use all the additional speed and safety of the 
Synthesis Cabrio .

3.3.1 TAKE OFF

Classic foot launch

Even when it seems that there is no wind at all, it is rarely so. Therefore 
always be careful in determining the conditions, as in PPG flying it is most 
important that the launch and initial climb are performed with a head wind 
(danger of losing your airspeed while crossing the wind gradient is greatly 
reduced). Special attention must be paid to trees, power lines and other 
obstacles, including the possibility of emerging rotors.

Wing preparation

Lay out the paraglider downwind of the power unit, with all suspension lines 
taut and pointing toward center of the power unit. The risers are to be laid on 
the ground. Set the trimmers at “0” (see fig. 2). In strong conditions faster 
settings can be advised. Make sure that you warm up the engine while 
standing windward of the wing. Stop the engine before clipping in the risers. 

Now have a quick check whether:

$

the helmet is on and locked,

$

the risers are clipped in the carabiners,

$

the trimmers are set,

$

nothing will get in propeller's way,
