EXTREME FLYING MANOEUVRES
WARNING!! All the critical flight conditions described here require thorough
knowledge. They should only be carried out during safety training courses (SIV)
under proper guidance
. Under any circumstances the present descriptions can
not be taken as manual for practising the 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 be
aware of these flight manoeuvres and prepare for them by SIV (safety training over
water). We expect you are an advanced paramotoring pilot and you already have the
proper experience. Mastering these flying conditions significantly improves your active
flight safety. 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.
Asymmetric collapse
A negative angle of attack can cause all or part of the leading-edge of the MacJet to
collapse (e.g. in very turbulent air). The MacJet will re-open spontaneously from
closures of up to 50%. 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. 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 canopy can enter a stable spiral dive.
“Cravat” / Line-over:
In the event of some lines becoming tangled during flight (caused by whatever), the
following action is recommended:
The pilot stabilizes the glider by gently applying the opposite brake. Please be aware
that in this condition the brake pressure can be higher and the brake travel shorter.
Without pilot input a line-over will result in a stable spiral dive.
Here are the various options to untangle a line-over:
- pumping the collapsed side.
- pulling the stabilizer line or a sharp pull on the D riser can solve the problem.
Attention! If these manoeuvres fail or if in any doubt, the pilot should instantly use their
emergency parachute system!
