Safety 

 

Glider categories and guidelines 

 

WARNING 

The  descriptions  of  flight  characteristics 
contained  in  this  Manual  are  all  based  on 
experiences from the test flights, which were 
carried out under standardised conditions. 
The  classification  is  merely  a  description  of 
the reactions to these standard tests. 
The  complexity  of  the  system  paraglider  - 
harness means that it is not possible to give 
any  more  than  a  partial  description  of  the 
glider’s  flight  behaviour  and  reactions  to 
disturbances.  Even  a  small  alteration  in 
individual  parameters  can  result  in  flight 
behaviour  which  is  markedly  modified  and 
different from the description given.

 

The  German  Hanggliding  and  Paragliding 
Association  (DHV)  and  its  safety  division  have 
developed  guidelines  which  are  based  on  many 
years  of  analysing  paraglider  accidents  and  on 
the  experience  of  flying  schools,  flying 
instructors and safety officers. These guidelines 
should  help  pilots  to  select  the  appropriate 
glider  classification  for  their  particular  level  of 
flying  ability.  The  information  below  relates  to 
the classification in  EN/LTF  certification. There 
is also further information on the website of the 
relevant licensing body. 

EN/LTF certification 

The TWIN RS 2 received  B classification in the 
final classification by the licensing body. 

Description of flight characteristics  
Paragliders  with  good  passive  safety  and 
forgiving  flying  characteristics.  Gliders  with 
some  resistance  to  departures  from  normal 
flight. 

Description of pilot skills required 
For  pilots  who  fly  “actively”  and  regularly  and 
who  are  able  to  stabilise  the  glider  overhead 
even in turbulent conditions. 

Target group and recommended flying 
experience 

The TWIN RS 2 was developed for professional 
tandem pilots. 
With  its  well  balanced,  uncomplicated  inflation 
behaviour,  the  playful  and  fatigue-free  handling 
as well as the excellent flair behaviour even in nil 
wind,  it  is  a  reliable  tool,  but  it  is  also  very 
convenient for private flying fun for two. 
It  offers  absolute  flying  pleasure  at  the  highest 
level of safety and performance. 

Suitability for training 

The TWIN RS 2 is suitable for use as a training 
glider. 
Please respect the national requirements.
