the same side. The collapse will normally open by itself but if that does 
not happen, pull completely on the brake line on the side, which has 
collapsed (100%). do this with a firm movement. You may have to repeat 
this operation to provoke the re-opening. Take care not to over-brake on 
the side that is still flying (turn control) and when the collapse has been 
solved; remember to let the wing recover its flying speed.

symmetric collapse
In normal flying conditions the design of the ICepeaK 8 ensures that a 
symmetric collapse is quite improbable. The profile of the wing has been 
designed to widely tolerate extreme changes in the angle of incidence. a 
symmetric collapse may occur in heavy turbulent conditions, on entry or 
exit of strong thermals or lack of adapting the use of the accelerator to the 
prevailing air conditions. symmetrical collapses usually re-inflate without 
the glider turning but you can symmetrically apply the brake lines with 
a quick deep pump to quicken the re-inflation. release the brake lines 
immediately to recover optimum flight speed.

Negative spin
This configuration is out of the normal flight behaviour of the ICepeaK 
8. Certain circumstances however, may provoke this configuration such 
as trying to turn when the wing is flying at very low speed (while heavily 
braking). It is not easy to give any recommendations about this situation 
since it varies depending on the circumstances. remember that you 
should restore the relative air speed over the wing. To achieve this, 
progressively reduce the pressure on the brake lines and let the wing gain 
speed. The normal reaction would be a lateral surge with a turn tendency 
no greater than 360º before restoring to normal flight conditions.

parachutal stall
If it does happen, the feeling would be that the wing would not be 
advancing; you would feel a kind of instability and a lack of pressure 
on the brake lines, although the canopy would appear to be correctly 
inflated. The correct reaction would be to release the pressure on the 
brake lines and push the a lines forward or rather lean your body to any

deep stall
The possibility of the ICepeaK 8 falling into this configuration during 
normal flight is very unlikely. This could happen if you are flying at a 
very low speed, whilst over steering in a number of manoeuvres and in 
turbulent conditions. To provoke a deep stall you have to take the wing to 
minimum flight speed by symmetrically pulling the brake lines, when you 
reach this point, continue pulling until you reach 100% and then hold. The 
glider will first fall behind you and then situate itself above you, rocking 
slightly, depending on how the manoeuvre was carried out. When you 
start to provoke a stall, be positive and do not doubt an instant. do not 
release the brake lines when half way through the manoeuvre. This would 
cause the glider to surge violently forward with great energy and may 
result in the wing below the pilot. It is very important that the pressure 
on the brake lines is maintained until the wing is well established vertical 
above.

To regain normal flight conditions, progressively and symmetrically 
release the brake lines, letting the speed be re-established. When the 
wing reaches the maximum advanced position ensure that the brakes 
are fully released. The wing will now surge forward, this is necessary so 
that air speed is completely restored over the wing. do not over brake 
at this point because the wing needs to recover speed to quit the stall 
configuration. If you have to control a possible symmetrical front stall, 
briefly and symmetrically pull on the brake lines and let go even when the 
wing is still ahead of you.

Wing tangle
a wing tangle may happen after an asymmetric collapse, the end of the 
wing is trapped between the lines (Cravat). This situation could rapidly 
cause the wing to turn, although it depends on the nature of the tangle. 

The correction manoeuvres are the same as those applied in the case 
of an asymmetrical collapse, control the turn tendency by applying the
