Summary:   "Active   

fl

ying"  

The   pilot   sits   upright   in   his   harness,   his   view   goes   in   the   direction   of   the   

fl

ight.  

He   constantly   responds   to   increasing   and   decreasing   brake   pressures   with   the   aim   of  
maintaining   a   constant   pressure   on   the   brake   lines.  

The   further   in   front   of   you   the   glider   pitches,   the   larger   the   brake   input   required,   but   for   a  
shorter   duration.  

When   brake   pressures   decrease,   brake   

fi

rmly;   when   brake   pressures   increase,   ease   off  

the   brakes.

Rapid   descent   techniques  

a

Many   

fl

ying   situations   call   for   a   very   rapid   descent   to   avoid   a   dangerous   situation,   e.g.   the   up  

current   from   a   cumulus   cloud,   an   approaching   cold   front   or   a   storm   front.  
    Rapid   descent   methods   should   all   be   practised   in   calm   conditions   and   at   su

cient   altitude   so  

that   a   pilot   is   then   able   to   employ   them   effectively   if   extreme   conditions   arise.   Rapid   descent  
techniques   are   divided   into   three   different   manoeuvres   which   increase   the   sink   rate   in   a   safe   and  
controllable   manner.  
    Big   ears   and   spiral   dives   are   generally   the   most   common   methods   of   descent.   Big   ears   can  
achieve   a   moderate   rate   of   descent   with   the   advantage   of   forward   speed   and   manoeuvrability.  
    Spiral   dives   attain   higher   rates   of   descent,   but   the   g-forces   can   be   signi

fi

cant   and   the  

manoeuvre   is   more   technically   demanding.   ‘B-stalls’   have   little   or   no   advantages   compared   to  
the   other   methods   of   descent   and   therefore   are   not   recommended   in   normal   situations.   Always  
try   to   avoid   the   need   to   use   these   descent   techniques.   Thoroughly   check   the   conditions   before  
launch,   and   pay   close   attention   to   how   the   day   develops.  
    All   of   these   options   will   also   strain   your   paraglider   and   should   be   avoided   if   you   want   to  
preserve   your   paraglider.   We   recommend   that   you   practice   the   rapid   descent   techniques   under  
professional   guidance   during   a   safety   training   course.  

 

  

}

The   spiral   dive   is   the   most   effective   method   for   making   a   rapid   descent,   and   can   allow   sink   rates  
of   up   to   20   m/s   to   be   reached.   It   is   suitable   where   there   is   a   high   ascent   rate   and   little   wind.  
    The   Yeti   Tandem   3   ful

fi

ls   the   EN   spiral   dive   requirements   and   has   no   tendency   to   remain   in   a  

stable   spiral   dive   under   normal   conditions.   The   certi

fi

cation   test   

fl

ights   are   carried   out   with   a  

de

fi

ned   carabiner   distance   (see   chapter   "Harness").   Deviations   from   this   setting,   unapproved  

harnesses   or   spirals   with   excessive   sink   can   change   the   maneuver   considerably;   pilot   action   may  
be   required.   In   such   cases,   exit   the   spiral   by   weight   shifting   to   the   outside   and   progressively  
applying   the   outside   brake.  
    Before   entering   a   spiral,   make   sure   you   have   adequate   height   for   recovery.   To   enter   the   spiral  
dive,   weight   shift   and   progressively   apply   the   inside   brake   until   the   glider   enters   the   spiral.   As   the  
glider   accelerates   into   the   spiral,   centre   your   weight   and   control   your   rate   of   descent   with   weight  
shift   and   outer   brake.
