9.5.2  ASYMMETRIC COLLAPSE 

If one side of the glider partially folds or collapses it is important to keep your flying 
direction by applying weight shift and some brake on the opposite side.  
The wing should re-inflate on its own without any input from the pilot.  
To help re-inflation it is possible to pull some brake on the collapsed side and release 
immediately.  
In the event of a big deflation, i.e. 70%, it is important to apply brake on the inflated side of 
the wing, but care must be taken not to pull too much as you could stall the flying side.  
The glider is very solid and has a strong tendency to re-inflate after collapse.  

9.5.3  FRONT STALL OR SYMMETRIC COLLAPSE 

In the event of a front stall the glider will normally re-inflate on its own immediately without 
any change of direction. To speed up re-inflation briefly apply 30%-40% brake (to pump 
open the leading edge). 

Do not hold the brakes down

 permanently to avoid an unwanted 

stall.  

9.5.4  SPIRAL DIVES 

The LIFT 450 has very good behaviour in spiral and has no tendency to stick in the spiral. 
By progressively applying brake on one side the glider can be put into a spiral dive. Safe 
high sink rates can be achieved like this. The spiral has to be exited slowly by releasing 
the brake over one complete turn or the glider may pitch forward and possibly suffer a 
collapse. 

Care must be taken that the pilot has enough height to exit the spiral safely.  
Sink rates in excess of 19m/s can be obtained. 

 

CAUTION: 

SOME GLIDERS CAN BE NEUTRAL IN SPIRAL AND MAY NOT EXIT WITHOUT PILOT 
INPUT. TO EXIT A NEUTRAL SPIRAL THE PILOT HAS TO APPLY BRAKE INPUT TO 
TURN OUT OF THE SPIRAL (ON THE OUTSIDE WING). AS SOON AS THE GLIDER 
STARTS TO SLOW DOWN IN THE SPIRAL THE OUTSIDE BRAKE MUST BE 
RELEASED. 
 
PILOTS CAN SUFFER BLACK OUTS IN SPIRALS AND THE PILOT HAS TO EXIT THE 
SPIRAL AS SOON AS he/she FEELS ANY ABNORMAL SYMPTOMS (Black dots in field 
of vision or light-headedness).  

9.5.5  STRONG TURBULENCE 

 
NEVER FLY IN STRONG TURBULENCE! 
If you unexpectedly encounter strong turbulence, fly with 

no brakes

 

applied

 to let the 

reflex stabilize the glider try to reach landing without the use of brake instead use the 
throttle to slow the descent (small course correction can be done by shifting the weight of 
pilot and passenger in the required direction).
