A Note About Slope Soaring 

 

Parachutes  were frequently used for slope soaring or paragliding in the past. While this is an 

acceptable use, it can be very dangerous. The following guidelines will reduce the danger: 

 
 
1)

 

Obtain  competent  instructor  before  atempting  any  slope  soaring.  Many  countries  have 

organization that certify instructors. 

2)

 

Know the site. Never be the first one to launch at a site. Talk to several people who have 

used  the  site  before  under  similar  weather  conditions.  Make  sure  the  site  is  free  of 
turbulence.  Turbulence  may  collapse  your  canopy  and  you  may  fall  all  the  way  to  the 
ground, causing severe injury or death. 
 

3)

 

Know the limitations of your canopy. Glide ratios, minimum sink rate, launch speed, flight 

speed,  tolerance  to  turbulence  and  recovery  characteristics  are  just  some  of  the  things 
you need to know. These all vary according to wing loading, jumper weight, and canopy 
type.  You  must  be  very  familiar  with  this  canopy  before  attempting  any  paragliding. 
Canopies  designed  specifically  for  paragliding  may  perform  much  better  than  this 
canopy. Therefore, do not judge the suitability of a site based on the performance of a 
paraglider. 
 

4)

 

Make sure that you can make the landing area before you launch. Check the flight path or 

obstacles. Don’t launch if there are any dangerous obstacles along your flight path. 
 

5)

 

Inspect your parachute frequently and thoroughly. In skydiving the jumper structurally tests 

his parachute every time he deploys it. If there is any structural deficiency the opening 
shock will normally cause failure at an altitude where he can safely deploy his reserve. A 
slope  soaring  pilot  is  not  so  fortunate.  Turbulence  can  collapse  a  canopy  and  the 
subsequent opening shock can be hard enough to cause a failure. This could happen at an 
altitude that is too low for the reserve to work. 
 

6)

 

We  recommend  you  use  a  reserve  designed  specifically  for  paragliding.  Because 

paragliding  reserves  are  frequently  required  to  work  at  very  low  altitudes,  a skydiving 
reserve is not adequate.
