In thermals, in addition to the inner brake, we recommend lightly
braking on the outside as well – this helps to control bank and speed
of rotation, i.e. you get better feedback from the wing. Additionally
this increases the stability of the wing tip. Tight, controlled turns and
smooth direction changes need practise but should be a skill all pilots
have mastered.
Please note:
if the paraglider is no longer steerable using the brake
lines (for example if they have become tangled) then the wing has
limited steering capacity through the C-risers.
This, in combination with weight-shift, still allows reasonable turn
correction. Using this technique also permits a safe landing. The
C-risers should not be pulled so hard that they cause the wing to stall.
Landing
Landing the PRION 4 is very simple. In turbulent conditions it is ad-
visable to make your approach whilst pulling a little brake in order to
increase stability and to increase the feeling for the wing‘s movement.
Immediately before touchdown the brakes should be pulled hard –
even to the point of stall.
Rapid descent techniques
To quickly lose height, we recommend three possible manoeuvres. We
have ordered these by degree of difficulty:
1) Big ears
To use big ears, both outer A-lines (fitted on a separate riser – split A-ris-
ers) should be pulled down simultaneously. The brake handles (without
an additional wrap) remain in your hands. As long as the lines are held
down the wingtips remain folded and this increases the sink rate.
If the speed bar is used as well, this increases sink and speed. This
also equalises the higher angle of attack caused by the increased drag
of the ears. With »big« big ears (if the A3 line is pulled further), it is
necessary to use the speed-bar to avoid the angle of attack becoming
critically high.
The correct length adjustment is important. If it is too short, there is
the danger that the wing is constantly accelerated, which should be
avoided at all costs. If the cords are too short there is the risk that the
speed bar is unreachable.
If the cords are set too long, it is not possible to accelerate the wing to
its maximum speed.
We recommend setting the cords a little too long when first fitting the
speed system, so that the free play can be judged during flight. Then
the slack can be taken up if necessary. Brummel hooks with three
holes assist with the simple adjustment of the cord length.
Using the speed system
Before take off or on connecting the risers to the harness, the Brummel
hooks on the speed system must to attached to those on the harness.
Please make it part of your pre-flight routine to connect the speed sys-
tem – it is important for your safety.
The PRION 4 is fitted with a very effective and smooth-running
speed system. Up to the maximum speed, the glide performance
remains very high. Pitch correction, i.e. active flying, in accelerated
flight should not be performed through the brakes, but using the speed
system. Therefore if the wing pitches forward, the pilot should not
brake, but reduce the acceleration.
In accelerated flight, steering should be performed either by weight-
shift or through asymmetrical speed bar use (by increasing the acceler-
ation on the left side, the wing will turn right).
Speed system geometrical data
If the entire range of the speed-system is utilised, in comparison to the
C-risers the A-risers are shortened by approximately 12 cm (all sizes).
Turning
Turning a wing is the combination of inner brake, outer brake and
weight-shift. The key is the correct dose of each element. One of the
features of the PRION 4 is its sensitive handling. To fly precise turns,
small brake inputs are sufficient.
Please note: using
the brakes during ac-
celerated flight is not
only detrimental to
performance, but (in
comparison to non-ac-
celerated flight) it
increased to likelihood
of collapses!
Please note: a full
stall – if initiated
too early – can lead
to heavy landings
or even serious
accidents. Therefore
the brakes should
only be pulled fully
immediately before
touching the ground
(<0.5 meters).
With »big« big ears
(if the A3 line is
pulled further), it is
necessary to use the
speed-bar to avoid
the angle of attack
becoming critically
high.
