2.1
Motorised operations
The flight behaviour of the Xduo with motor is quite identical to that described in the Xduo
manual chapter “The Flight”. Due to the higher wing and surface loading in the extended
engine weight range, the according reactions are responding more dynamically. Opening the
trimmer reduces the angle of attack and also causes a higher speed and thus more dynamic
behaviour. It is recommended to keep the trimmers closed when flying through turbulent air.
In order to keep the take-off distance and take-off speed low, the trimmers remain closed
during take-off, especially when there is little wind. Although the Xduo has outstanding take-
off properties, attention must be paid that due to the extended engine weight range the take-
off and landing speed changes and alters noticeably.
2.2
E-climbing assistance/ E-ascent aid
Due to its unproblematic handling and high trim speed, the GRAVITY Xduo is ideally suited
for the e-ascent aid.
2.3
Towing winches
The Xduo has no specifics when it comes to winching. But here a few tips that we urge every
pilot to take into consideration. If you are not operating at your usual winch, get acquainted
with the local procedures. Every visitor on unfamiliar flying grounds needs to get a good
briefing by a local pilot. At the start take special care that the glider is completely over the
pilot’s head before the start commando is given. Eventual corrections to the direction with
the brakes should not be applied before the canopy is over the pilot, otherwise the glider
could fall back through too intense braking or the glider is towed away in non-flight-ready
condition. The start commando must not be given before the glider is under absolute control.
Strong direction correction during the start phase and before reaching the safety height are
to be avoided. Attention also needs to be paid to the fact that a shallow angle is kept until
reaching safety height. Do not use a tow line tension over 150 kp with the Xduo.
–
Never tow the GRAVITY Xduo with a load exceeding the approved weight limits
–
All persons and facilities involved in winch operation must have the required
qualifications or approvals for towing paragliders on the winch. This applies to the
pilot, winch operator, towing device, towing pawl and all other devices for which a
certificate of competence is required
