Pilot Profile 

 
Additionally,  the  exceptional  low  speed  flight  characteristics  of  the  wing  are  causing  a 
minimal take-off speed and much control time during the start. The Xcend light is based on 
a  new  layout  and  a  modified  wing  profile  which  combines  gliding  performance  with  a 
remarkable  tolerance  spectrum.  Chief-designer  Ernst  Strobl  equipped  the  Xcend  light  with 
36  cells  and  an  aspect  ratio  of  5  and  fits  the  wing  with  the  latest  technical  features.  In 
addition to the PPN, 3D shaping assures optimized inflow and shape stability of the leading 
edge.  Extensive  calculations  of  the  ballooning  in  combination  with  the  optimized  wing 
preload  ensure  a  balanced  pressure  distribution  and  flow  dynamics  around  the  profile.  On 
the  rear/  trailing  edge  of  the  wing,  mini-ribs  give  the  profile  more  shape  retention  and 
additionally enhancing the aerodynamics, especially when braking.
