Negative spin

A negative spin does not conform to the SKIN 2, normal flight behaviour. 
Certain circumstances however, may provoke a negative spin (such as 
trying to turn when flying at very low air speed whilst applying a lot of 
brake). It is not easy to give any specific recommendation about this 
situation other than quickly restoring the wing’s default air speed and 
angle of attack by progressively reducing the tension on the brake lines. 
The normal wing reaction will be to have a lateral surge on the re-
accelerated side with a rotation not greater than 360º before returning to 
default air speed and a straight flight path trajectory.

Parachutal stall

The possibility of entering or remaining in a parachutal stall have been 
eliminated from the SKIN 2.
A parachutal stall is virtually impossible with this wing.  If it did enter into 
a parachutal stall, the wing loses forward motion, becomes unstable 
and there is a lack of pressure on the brake lines, although the canopy 
appears to be fully inflated. To regain normal air speed, release brake line 
tension symmetrically and manually push on the A-lines or weight-shift 
your body to any side WITHOUT PULLING ON THE BRAKE LINES.

Deep Stall

The possibility of the SKIN 2 stalling during normal flight is very unlikely. 
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 minimum 
air speed by symmetrically pulling the brake lines all the way (100%) 
down until the stall point is reached and held there. The glider will first 
pitch 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 lines 
until reaching the half-way point of the total the brake travel. The wing 
will then surge violently forward and could reach a point below the 

pilot. It is most important to maintain brake pressure until the glider has 
returned to its default overhead flying position.

To resume normal flight conditions, progressively and symmetrically 
release the brake line tension to regain air speed. When the wing reaches 
the overhead position, the brakes must be fully released. The wing will 
then surge forward to regain full air speed. Do not brake excessively at 
this moment as the wing needs to accelerate to pull away from the stall 
configuration. If you have to control a possible frontal collapse, briefly 
pull both break handles down to bring the wing back up and release 
them immediately while the glider is still in transition to reposition itself 
overhead.

Cravat

A cravat may happen after an asymmetric collapse, when the end 
of the wing is trapped between the lines. Depending on the nature 
of the tangle, this situation could rapidly cause the wing to spin. The 
corrective manoeuvres to use are the same as those applied in case of 
an asymmetric collapse:  control the turn/spin by applying tension on 
the opposite brake and weight shift opposite to the turn. Then locate the 
stabilo line (attached to the wing tip) trapped between the other lines. 
This line has a different colour and is located on the outside position of 
the B-riser.

Pull this line until it is taut.  This action will help to release the cravat.  If 
ineffective, fly down to the nearest possible landing spot, controlling the 
direction with both weight-shift and the use of the brake opposite to the 
tangled side. Be cautious when attempting to undo a tangle while flying 
near terrain or other paragliders; it may not be possible to continue on 
the intended flight path.

Over-controlling

Most flying problems are caused by wrong pilot input, which then 
escalates into a cascade of unwanted and unpredicted incidents. We 
should note that the wrong inputs can lead to loss of control of the glider.
