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 Warp 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 Warp 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. Warp is equipped with
an automatically operating TEA line (Torque Effect Adjuster).
Unsymmetrical TEA assembly is an efficient countermeasure against
the turning moment.
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:
<
change the throttle setting and/or
<
use the TEA system by fixing the line on the side opposite to the
torque direction and/or
<
shift yourself to the other side of the harness
The best method is to fasten opposite cross-bracing, or apply some
weight-shift. Such oscillations usually occur at full power - the
climbing
