In turbulence
Deflations of the canopy can occur in strong turbulence. The Boomerang 4 will recover in most
situations, but it’s recommended to open it in a controlled manner with the brakes. Only if the
wing surges very fast in front of you should you stop it with the brakes. However, it is
recommended that you follow the advice below in order to help the wing recover more rapidly.
Asymmetric deflation
In the event of encountering strong turbulence and suffering an asymmetric deflation (collapse
on one side), the Boomerang 4 will have a tendency to re-inflate by itself, but the wing will turn
towards the collapsed side. This might be unwanted close to the ground or other gliders.
Maintain your course by weightshifting away from the collapsed side. This action can be aided
by applying a little force on the brake opposite to the deflation. This will normally be sufficient
for recovery. However, it is sometimes necessary to pump out the deflated side with a firm and
smooth pumping motion. Let the glider regain its flying speed after it has re-inflated.
If you have a big collapse - especially when flying accelerated - you must observe the following:
When a big collapse happens, due to the difference in weight and inertia of the canopy and pilot,
the pilot will continue to travel forward and the canopy will fall behind the pilot, especially
when flying accelerated. You must wait until you pendulum back below the canopy before
reacting and carefully counter braking the open side of the canopy. If you react too early, you
risk stalling the collapsed canopy completely and the following scenario can become
uncontrollable.
When you have a big collapse in accelerated flight you must first release the speed bar
immediately. Stay neutral with your weight and brake the open side slightly. Let the glider turn,
if you have enough space. This is the optimum action to avoid a spin or stall and help your
glider to recover as fast as possible.
Symmetric deflation
A symmetric (frontal) deflation will normally reopen by itself without strong pilot input. The
glider will regain airspeed with a small surge. If counter braking, be careful not to over-correct
or to brake too early, when the glider is still behind you - danger of a stall!
Cravat / glider wrapped around lines
A cravat occurs after a severe deflation when the wingtip becomes trapped in the glider lines. It
can occur on the Boomerang 4, usually after big deflations or in cascading situations. The pilot
should be familiar with the procedure for correcting it. Counter brake and/or weightshift and
pump the brake on the tangled side. On the Boomerang 4 there is a separate stabilizer/winglet
main line that goes down to the C-riser. This line usually becomes slack in the event of a cravat.
Pull it down completely until it becomes tight and the cravat normally comes out.
