Dangerous situations and 
extreme flying 

Dangerous situations 

Pilot  error,  extreme  wind  conditions  or 
turbulence  which  the  pilot  does  not  notice 
quickly  enough  may  put  the  wing  in  an  unusual 
flying  position,  requiring  special  reaction  and 
skills  on  the  part  of  the  pilot.  The  best  way  to 
learn  how  to  react  calmly  and  correctly  in  a 
serious  situation  is  to  attend  safety  training, 
where  you  will  learn  how  to  manage  extreme 
situations under the guidance of a professional. 
Ground-training  is  another  safe  and  effective 
method  of  familiarising  yourself  with  your 
glider’s  reactions.  Launch  can  be  practised,  as 
can  small  flying  manoeuvres,  such  as  stall, 
asymmetric collapse, front stall etc. 
Any pilot who flies in turbulent conditions or who 
makes  an error  in handling  the glider  is  at  risk 
of  getting  into  an  extreme  situation.  All  of  the 
extreme  flight  figures  and  flight  attitudes 
described  here  are  dangerous  if  they  are 
carried out with  inadequate  knowledge, without 
the right safety altitude or without training. 
Please note that if a harness different from the 
one  used  for  the  type-test  certification  is  used, 
flight behaviour may vary from that described in 
this Manual. 

Safety training 

 

WARNING 

These  instructions  are  not  a  substitute  for 
the  need  for  safety  training.  We  therefore 
recommend  that  you  take  part  in  special 
safety  training  which  will  teach  you  how  to 
handle extreme situations. 

Taking  part  in  safety  training  is  in  principle 
advisable  in  order  to  familiarise  yourself  with 
your glider and the correct reactions in extreme 
situations.  However,  safety  training  also 
subjects your equipment to extreme loads. 

Material stress and damage 

SWING advises against subjecting the materials 
of the TWIN RS 2 to excessive stress  during a 
safety training (SIV) course. 
Uncontrolled  flight  positions  can  occur  during 
safety  training,  which  are  outside  the 
manufacturer’s  limits  for  the  paraglider  and 
which can put the glider under excessive stress. 
Trimming  the  line  lengths  and  canopy  material 
after  safety  training  can  lead  to  a  general 
deterioration in flight characteristics. 
Damage  as  a  result  of  safety  training  is  not 
covered by the warranty. 

Safety training and RAST 

Most  manoeuvres  can  be  practised  with  the 
TWIN  RS  2  during  safety  training  in  the  same 
way as with a glider without RAST. 
Only  those  manoeuvres  for  which  the  glider 
must  be  actively  collapsed  (asymmetric 
collapse, front collapse) require higher forces to 
enter as a rule than would be necessary with a 
glider without RAST. 

 

WARNING 

Refrain from doing wingovers with the glider 
to  make  a  more  large-scale  collapse 
possible. 
A  provoked  collapse  from  a  roll  or  pitch 
movement  can  lead  to  uncontrolled  flight 
positions. Such collapses are unrealistic and 
have no training benefit. 

 

WARNING 

Always keep within the recommended limits. 
Avoid  aerobatics  and  extreme  loading  such 
as  spirals  and  big  ears.  This  will  prevent 
accidents and avoid over-loading the glider. 
In  turbulent  conditions,  always  keep  enough 
distance  from  rock  faces  and  other 
obstacles.  Time  and  sufficient  altitude  are 
needed to recover from extreme situations. 
Deploy  your  reserve  if  the  corrective 
manoeuvres  described  in  the  following 
sections  do  not  return  the  glider  to  a 
controllable  flying  position  or  if  there  is  not 
enough altitude for correction.
