Pilot’s manual for Montana3 

 

Recovery:  Montana3  recovers  from  a  Spiral  Dive  automatically  as  soon  as  the  brakes  are  released. 
Release them smoothly and always finish a Spiral Dive with safe altitude! 

CAUTION: When exiting the Spiral Dive make sure your position in the harness is neutral. Recovery from a 
Spiral Dive can be delayed if you are weight shifting to the inner side of the turn. 

5.3. SIV manoeuvres 

No matter what category of canopy you fly or what level of certification it has, in turbulence or in strong 
thermals you may experience all kinds of collapses.  

Montana3 behaves comfortably in these situations. Indeed not only does the glider deal with extreme 
flight situations automatically, but it also offers – for its category – an above-average degree of safety. 
Even so, you must follow all safety rules when practising SIV. Always pay attention to your altitude. 

Before performing any SIV manoeuvre remember: 

 

Practise throwing your reserve on the ground, in a simulator, so that reserve deployment is efficient 
and automatic. 

 

Rapid altitude loss and considerable rotational forces may develop during unstable manoeuvres. 
Take account of these factors when throwing your reserve. 

5.3.1. Asymmetric Collapse – one side of the canopy collapses 

Initiation: Grab the outer A-line on one side and pull it down smoothly. The wing tip will collapse to 
form a characteristic Big Ear. The size of the ear depends on the depth to which the lines are pulled. 
You can stop any turn tendency by applying the opposite brake and by weight shifting onto the inflated 
side of the canopy. 

Recovery: Under normal conditions Montana3 will reinflate spontaneously when the pulled lines are 
released. Inflation time and loss of altitude can be reduced by suitable piloting. To stop any tendency 
to turn off course pull the brake on the inflated side (be careful not to overreact and stall the inflated 
side) and weight shift to that side. If the collapse remains then reinflate the collapsed side by ‘pumping’ 
the brake on the collapsed side. 

CAUTION: It is very important to execute this manoeuvre very carefully. Due to the high compactness 
of the leading edge and collapse resistance it is quite difficult to find a right degree of pulling of A-risers 
down. This applies particularly to the asymmetric collapse of 75% at full speed!  

5.3.2. Full Frontal Collapse 

Initiation: Grab both A-risers at the top and pull them down fluently until the leading edge collapses. 

Recovery:  Recovery  time  depends  on  how  much  of  the  canopy  has  collapsed.  In  normal  conditions 
Montana3 will recover into normal flight automatically as soon as the front risers are released. Applying 
the brakes on both sides simultaneously can help reopen the paraglider
.   

CAUTION: It is very important to execute this manoeuvre very carefully. Due to the high compactness 
of the leading edge it is quite difficult to find a right degree of pulling of A-risers down. If you pull them 
down too quickly, a massive collapse could happen!  

5.3.3. Deep stall 

Initiation:  Pull  both  brakes  smoothly  until  the  sink  rate  increases  markedly  and  the  forward  speed 
reaches almost zero. The pull on the brakes should be controlled so that the canopy stays inflated and 
doesn't fall back into a full stall. 

Recovery:  Montana3  cannot  stay  in  deep  stall  flight,  so  after  the  brakes  are  released  the  glider 
automatically returns to normal flight. If you need to, you can accelerate recovery by pulling hard on 
both brakes, followed by a fast release. Or you can pull lightly on the A-risers. 

CAUTION: If you pull too hard on the A-risers you may experience a full frontal collapse.
