B-Li ne Stal l
This is a fast descent method and is a useful emergency procedure. With both hands through the
brake handles, the pilot takes hold of the top of the B risers, one in each hand, and pulls them down
by around 50 cm. This will stall the canopy and forward speed will drop tp zero. Make sure you have
plenty of ground clearance because the decent rate can be over 10 m/sec. To increase the descent
rate pull harder on the B riser. When you release the B riser the canopy will automatically start flying
again, normally within two seconds. Sometimes the canopy will turn gently when it exits from the B
line stall. It is normally better to release the B riser fairly quickly rather than slowly as this may result
in the canopy entering deep stall. Always release the riser symmetrically as an asymmetric release
from a B line stall may result in the glider entering a spin. This manoeuvre is useful when losing a lot of
height quickly is necessary, perhaps when escaping from a thunderstorm. It should not be performed
with less than 100 m of ground clearance. (see also Chapter V, part 1)
