12Parachutal stallThe possibility of entering or remaining in a parachutal stall have beeneliminated from the SKIN 2 P.A parachutal stall is virtually impossible with this wing. If it did enter intoa parachutal stall, the wing loses forward motion, becomes unstableand there is a lack of pressure on the brake lines, although the canopyappears to be fully inflated. To regain normal air speed, release brake linetension symmetrically and manually push on the A-lines or weight-shiftyour body to any side WITHOUT PULLING ON THE BRAKE LINES.Deep StallThe possibility of the SKIN 2 P stalling during normal flight is veryunlikely. It could only happen if you are flying at a very low air speed,whilst over-steering or performing dangerous manoeuvres in turbulent air.To provoke a deep stall, the wing has to be slowed down to its minimumair speed by symmetrically pulling the brake lines all the way (100%)down until the stall point is reached and held there. The glider will firstpitch rearward and then reposition itself overhead, rocking slightly,depending on how the manoeuvre was done.When entering a stall, remain clear-headed and ease off the brake linesuntil reaching the half-way point of the total the brake travel. The wingwill then surge violently forward and could reach a point below thepilot. It is most important to maintain brake pressure until the glider hasreturned to its default overhead flying position.To resume normal flight conditions, progressively and symmetricallyrelease the brake line tension to regain air speed. When the wing reachesthe overhead position, the brakes must be fully released. The wing willthen surge forward to regain full air speed. Do not brake excessively atthis moment as the wing needs to accelerate to pull away from the stallconfiguration. If you have to control a possible frontal collapse, brieflypull both brake handles down to bring the wing back up and releasethem immediately while the glider is still in transition to reposition itselfoverhead.CravatA cravat may happen after an asymmetric collapse, when the endof the wing is trapped between the lines. Depending on the natureof the tangle, this situation could rapidly cause the wing to spin. Thecorrective manoeuvres to use are the same as those applied in case ofan asymmetric collapse: control the turn/spin by applying tension onthe opposite brake and weight shift opposite to the turn. Then locatethe 3STI stabilo line (attached to the wing tip) trapped between theother lines. This line has a different colour and is located on the outsideposition of the B-riser.Pull this line until it is taut. This action will help to release the cravat. Ifineffective, fly down to the nearest possible landing spot, controlling thedirection with both weight-shift and the use of the brake opposite to thetangled side. Be cautious when attempting to undo a tangle while flyingnear terrain or other paragliders; it may not be possible to continue onthe intended flight path.Over-controllingMost flying problems are caused by wrong pilot input, which thenescalates into a cascade of unwanted and unpredicted incidents. Weshould note that the wrong inputs can lead to loss of control of the glider.The SKIN 2 P was designed to recover by itself in most cases. Do not tryto over-correct it!Generally speaking, the reactions of the wing, which are caused by toomuch input, are due to the length of time the pilot continues to over–control the wing. You have to allow the glider to re-establish normal flyingspeed and attitude after any type of incident.4.3 ACCELERATED FLIGHTThe SKIN 2 P profile was designed for stable flight throughout its entire
