Climbing
Once you took off safely, continue heading against the wind, using
brakes to correct rate of climb.
Do not try to climb too steeply - attempts to increase climb rate by
pulling the brakes will have an adverse effect, as due to additional
drag the actual rate of climb will worsen and with the throttle fully
opened even a stall can occur.
In powered flight the Universal 1.1 behaves more like an aeroplane
than a paraglider, and it is good idea to regard it as such.If there
are no obstacles present, it is by far safer (and more impressive for
the spectators) to level for a while after take-off and gain some
speed before converting it to height with a brief pull on the brakes.
Another reason not to try climbing too steeply is the risk connected
with engine failure at low altitude. Even as the Universal 1.1 in a
steep climb does not stay behind as much as conventional
paragliders do, the low speed is more likely to cause a stall.
Besides, you should always be able to land safely in case of engine
malfunction, so it’s better not to take unnecessary chances and
always fly with a safe margin of speed.
Depending on the power unit geometry, it is possible that after
take-off you will notice a propeller torque (turning moment). It will
try to turn you around, so counteract with a brake or harness'
cross-bracing.
The risers of the Universal 1.1 feature double main carabiner loops
(upper and lower). Asymmetrical suspension (placing the risers a
different heights) is an effective countermeasure agains the torque
in case when harness lacks the cross-bracings.
When climbing steeply with slow trim settings and high power
output keep in mind the risk of stalling!
Due to typical PPG feature - considerable vertical distance between
thrust axis and wing chord - the range of safe power operation is
closely connected to your skills and equipment.
Power-unit induced oscillations
Certain configurations of engine weight, output and propeller
diameter can cause serious oscillations, during which the pilot is
being lifted to one side by the torque effect, swings down due to
his weight, then is lifted again and so on.
To avoid this you can:
