MOTORISED FLIGHT
Yukon is certified for powered flying.
Note!! Although, motorized flight can be a great success due to the gliders very easy take-off
characteristics, stability and good handling, always use a certified combination of engine - harness
and glider. If in doubt check with your federation. Contact the manufacturer or importer for the
current legality of motorized flight.
WARNING!! The Yukon is not suitable for jumps from aircraft.
WARNING!! The Yukon is not designed to be used for aerobatics.
EXTREME FLYING MANOEUVRES
This section describes flying conditions which can be deliberately induced, or which can
develop unintentionally due to turbulence or pilot error. Any pilot who flies through
turbulence is sure to be faced with these special flight conditions at some point. So take
a good look at these flight manoeuvres or prepare for them by SIV (safety training over
water). Mastering these flying conditions significantly improves your active flight safety.
Sufficient height, as well as the carrying of a reserve parachute, is imperative.
WARNING!! All the critical flight conditions described here require thorough knowledge;
otherwise carrying them out may be very dangerous. Sufficient height above the ground
is imperative. Bear in mind that all disturbances of the canopy can increase the sink rate
by 2 - 10 m/sec, depending on the degree of disturbance. Carrying out these
manoeuvres wrongly may lead to a crash.
Remember this is a glider with unspectacular reactions to disturbances in the air.
Whenever in doubt, raise the brakes and let the glider fly. The glider has a high internal
pressure, resistance to tucking and very high degree of passive safety. It is
recommended that at this stage you already practise an active flying style. The key to
active piloting is keeping the glider above your head at all times. We recommend in
principle that you hold the brake handle in your hand whenever possible, or fly with your
hands through the brake handles, to allow you to react immediately to any possible
disturbances. .
WARNING!! If you fly with your hands through the brake handles, you may lose valuable
time in activating the rescue system.
Asymmetric collapse:
A negative angle of attack can cause all or part of the leading-edge of the Yukon to
collapse (e.g. in turbulent air). Basically the Yukon will re-open spontaneously from
closures of up to 70% with a change of direction of up to 90°. The time this takes, and
the associated height loss, can however be noticeably reduced by appropriate action by
the pilot. Apply opposite brake on the inflated side, the outside of the curve, to stop the
turning movement of the canopy. This should be accompanied by appropriate weight-
shift. If you react immediately, 30% brake on the open side should suffice to hold the
canopy on a straight course. In the event of a big collapse, this braking should be
applied very carefully to avoid stalling the remaining inflated wing. The pilot's correction
for direction can be aided by a pumping out the deflation; a slow, long pumping action of
the brake of the deflated side of the wing helps the canopy to re-inflate. If the pilot does
not correct, the Yukon usually self-recovers. However, if it does not self recover and the
pilot does not correct the canopy can enter a stable spiral dive.
