and your lines.
IMPORTANT SATEFY NOTICE: A pilot who is dehydrated and/or not accustomed to spiralling
can lose consciousness during a steep spiral dive!
Due to the 2-line construction it is not possible to make a B-line stall. If it happens that the B-
risers are pulled too much (via B-riser control) and the glider enters a deep stall, the B-risers
have to be released immediately. The glider will recover itself from the deep-stall then.
Making Big-Ears can cause cravats on the tips. To reduce the tendency of a cravat we
recommend to take the AR3 and the stabile-line (BR4) at same time for making big ears.
We recommend making Big-Ears with the most outer B-line instead. See next point...
By pulling down the most outer B-line the tips make a partial B-stall, which gives a very similar
result compared to doing it with the A-lines. To release, just put the B-lines up again. The
advantage by doing so is that the ears are more stable and have no tendency to shake. A
disadvantage would be that the ears cannot be alternated in size. This manoeuvre works in
trim speed as well when accelerated. It takes some practice to achieve this manoeuvre.
ALL RAPID DESCENT MANOEUVRES SHOULD BE FIRST PRACTICED IN CALM AIR, WITH
SUFFICIENT ALTITUDE AND WITH QUALIFIED SUPERVISION.
REMEMBER:
A wrong manoeuvre at the wrong time may change a straightforward situation into a
dangerous problem. Extreme manoeuvres also expose your glider to forces which may damage
it.

Practice these techniques under qualified supervision preferably during a safety
training course.

Before initiating a manoeuvre, make sure that the airspace below is clear of
obstructions or other pilots.

During manoeuvres, watch both the glider and altitude above the ground.
Use of reserve:
If you lose control or if you are not absolutely sure that you have enough height for further
attempts to recover, immediately use your reserve!

Maintenance and Repairs

The materials used to construct your PURE3 have been carefully chosen for maximum
durability. If you treat your glider carefully and follow these guidelines, it will last you a long
time. Excessive wear can occur by bad ground-handling, careless packing, unnecessary
exposure to UV light, exposure to chemicals, heat and moisture.
