6.7

 

Pilot/ Passenger Configuration     

 
There are two ways of starting: one behind the other (passenger in front) or side by side.  
 

6.8

 

Behind Each Other 

 

For the method of starting in succession, it says that the passenger does not swing forward 
after the start and can be pushed in right direction during the acceleration phase. In addition, 
it can be prevented that the passenger sits down in the harness too quickly by an additional 
impulse with the knee.     
 

6.9

 

Juxtaposition 

 

The advantage of starting next to each other is better possibility for running and freedom of 
movement.  Even  with  a  reverse  start,  this  technique  offers  certain  advantages.  Often  a 
disadvantage that is mentioned is that the passenger swings in the starting direction after the 
start.  By  holding  onto  the  passenger  at  the  chest  belt  or  the  cross  bracing  of  the  pilot, 
however, this can be prevented and a synchronicity in the running direction can be achieved. 
This  starting  position  is  more  problematic  in  strong  winds  as  the  passenger  is  less  able  to 
brace himself against the wind. So he cannot exert pressure to the front and take almost no 
influence on the paraglider during the mounting process.  In such a case, therefore, a reverse 
start or help in take-off by two well-versed pilots can be the better choice. At the behind-
each-other  starting  method  the  passenger  best  holds  onto  the  loop  of  the  T-bar  i.e.  short 
above the carabiners. At the Juxtaposition starting method he grabs the pelvis or chest belt 
of the pilot.     
 

  

 

PAY  ATTENTION_

  Immediately  before  take-off,  the  pilot  must  again  check  both 

harnesses, carabiners, suspension (T-bar), lines - including the brakes, and the correct position 
of the paraglider (5-point-check).       
 

6.10

 

Inflating the Paraglider      

 
The paraglider is inflated by the pilot as described in the chapter “Flight Practice / The Start”. 
This process can be facilitated in particular with the starting method “one behind the other” 
in that the passenger grabs the T-bar above the carabiners and thus helps to pull the glider 
up. This has the further advantage that the passenger has something in his hand and is actively 
involved in the starting process.   It is important for the pilot to carefully check whether the 
glider  is  filled  correctly  or  if  it  has  to  be  aborted.  In  case  of  problems  an  immediate  abort 
occurs, otherwise now - with properly filled canopy and untwisted lines - the decision to start 
with the command “run” to the passenger occurs. After the command “run” a fast acceleration 
takes place up to the lifting point. If the passenger runs too timid, the command “run” should 
be repeated aloud and the passenger may be encouraged to accelerate by pressure from the 
pilot.
