Full Stall 

To create a ‘Full Stall’, the pilot must pull both brakes to the end, and hold them tightly 
in this position. In this situation, the

 flies in most times on reverse, in a forward 

horseshoe shaped tie. The canopy must be stabilized before the procedure for normal 
flight re-entry is initiated. Any attempt of recover during the beginning stages of a stall, 
when the  power  glider  reverses  suddenly  can  result  in  a  sudden push  forward  of  the 
canopy. 
When  recovering  from  a  'Full  Stall',  both  brakes  must  be  released  slowly 
simultaneously  and  symmetrically  (>  =  1  second).  The

  will  move  forward 

gradually and begin normal flying. 
An  asymmetric  recovery  (releasing  one  brake  before  the  other)  of  a  'Full  Stall'  is 
utilized only by test pilots to simulate a power glider being expelled out of a thermal 
and must not be attempted by pilots!

Negative Turns 

To  induce  a  fast  Negative  Turn  out  of  normal  velocity  (LTF)  or  starting  from  the 
minimum speed (EN), the pilot must pull tightly and quickly one toggle right to the end 
of it. 
During the negative spiral, the canopy rotates relatively fast around its center, with its 
inner side flying backwards. 
When entering an unintentional Negative Turn, the pilot must recover as soon as it is 
noticed by releasing the brake slightly so that the canopy will accelerate and returns to 
a stable flight, without losing too much altitude. 
When  a  negative  turn  is  intentionally  prolonged,  the

accelerates  forward 

asymmetrically.  A  frontal  asymmetric  closing  should  not  be  under-estimated.  To 
recover from an intentional negative spiral, the pilot must release the pulled brake and 
pay close attention to a strong canopy surge ahead.
