5.2.4 CRAVAT
In case a cravat should occur from an asymmetric collapse or other manoeuvres, it is
important to keep your flying direction by applying some brake on the opposite side and then
it can usually be opened by pulling down on the stabilo line of the affected side while
countering the turn with the opposite brake and weight shift.
5.2.5 FRONT STALL OR SYMMETRIC COLLAPSE
In the event of a front stall the glider will normally re-inflate on its own immediately without
any change of direction. To speed up re-inflation briefly apply 30%-40% brake (to pump
open the leading edge).
Do not hold the brakes down permanently to avoid an unwanted
stall.
5.2.6 B-STALL
The NRG PRO II/NRG XC II has a very clean, stable B stall.
To enter the B stall the pilot has to pull the first 20-cm slowly until the glider loses forward
speed and starts to descend vertically.
Then the pilot can pull more on the B until he/she attains a stable 7 to 9 m/s descent rate.
The Glider has no tendency to front rosette or become pitch unstable. To exit the B stall the
pilot releases the B slowly until the glider has regained its shape and then the
last 15 cm
fast to prevent the glider from entering deep stall.
The NRG PRO II/NRG XC II can be controlled directionally in the B stall by pulling more on
one B riser than on the other to create a turn in any direction. The B-stall is a safe controlled
way of losing altitude fast without any forward speed.
5.2.7 BIG EARS
Big ears manoeuvre is not available using the NRG PRO II/NRG XC II.
5.2.8 DEEP STALL OR PARACHUTAL STALL
Under normal flying conditions the NRG PRO II/NRG XC II will have no tendency to enter
deep stall. All gliders can however under certain conditions enter and stay in deep stall
configuration (as a result of ageing of materials, improper maintenance or pilot induced).
5.2.8.1 Signs of parachutal stall
• The pilot has very little or no forward airspeed and no wind in his face.
• The glider will be fully open but the cells will be bulging in and not out on the bottom
surface.
• The glider might have a very slow turning sensation.
• You will have an increased vertical descent.
5.2.8.2 Exit from parachutal stall
It is important to recognize this situation. Most accidents involving parachutal stall happen
because the pilot did not realize that he was in deep stall.
The best way to exit a parachutal stall is to pull all the A risers down to get the wing flying
again. The pilot can pull the riser down until the wing starts to fly again. The moment the
