Niviuk LINK 2, User Manual

from one size of wing to another, and even within the same size the 
behaviour and reactions may be different depending on the wing-loading.

In the test report, you will find all the necessary information on how to 
handle your new wing during each of the tested manoeuvres. Having this 
information is crucial to know how to react during these manoeuvres in 
real flight, so you can deal with these situations as safely as possible.

Asymmetric collapse

In spite of the LINK 2’s profile stability, strong turbulent air may cause 
the wing to collapse asymmetrically in very strong turbulence, especially 
if you do not fly actively and prevent the collapse. In this case the glider 
conveys a loss of pressure through the brake lines and the harness. 
To prevent the collapse from happening, pull the brake handle on the 
affected side of the wing. It will increase the incidence of the wing 
(angle of attack). If the collapse does happen, the LINK 2 will not react 
violently, the turning tendency is gradual and easily controlled. Weight-
shift toward the open, flying side (the opposite side of the collapse) to 
keep the wing flying straight, while applying light brake pressure to that 
side if necessary. Normally, the collapsed side of the wing should then 
recover and reopen by itself. If it does not, then pull the brake handle on 
the collapsed side decisively and quickly all the way (100%) down. You 
may have to repeat this pumping action to provoke the re-opening of the 
deflated glider side. Do not over-brake or slow down the flying side of the 
wing (control the turn). Once the collapsed side is open make sure you 
return to normal flying speed.

Frontal collapse

Due to the LINK 2’s design, in normal flying conditions frontal collapses 
are unlikely to take place. The wing’s profile has great buffering abilities 
when dealing with extreme incidence changes. A frontal collapse 
may occur in strong turbulent conditions, entering or exiting powerful 
thermals. Frontal collapses usually re-inflate without the glider turning, 
but a symmetrically applied quick braking action with a quick deep pump 
of both brakes will accelerate the re-inflation if necessary. Release the 

brake lines immediately to return to default glider air speed.

Negative spin

A negative spin does not conform to the LINK 2’s 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 LINK 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 LINK 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 is done. 

When entering a stall, remain clear-headed and ease off the brake lines
